Sandhill Plastic

The word plastic is derived from the Latin word plasticus which means “capable of being molded.” Indeed, plastics are moldable synthetic materials made up of a large organic molecule that can be formed into a variety of products. Depending on its purpose, plastics can be made as hard as stone or as pliable and elastic as rubber. Plastic can also be made to be as strong as steel, impact-resistant and heat-resistant. The processes involved in manufacturing the different kinds of plastic varies, and like metals, may be alloyed, or even combined with other materials. The other qualities that make plastics more distinct are being lightweight, waterproof and chemical resistant; they may also be produced in almost any color. More and more types of plastic are being studied and developed daily to further enhance the quintessential product that everybody benefits from.

Plastics also come in a variety of kinds, although all share the common characteristic of malleability or plasticity, they differ in properties, production costs, and the process of making them. Although plastics may be classified in many ways, they are commonly categorized based on the polymer element that is used as the basis in their production.

Common Plastics and How We Use Them

Inevitably, plastics have become a part of our lives. Life would certainly be very difficult without them. The countless kinds of plastics have found their way into industries and our homes and have gained permanency in both settings. The most commonly used plastics are: polyethylene, which has a wide range of uses and is very inexpensive; polypropylene used for the production of food containers and appliances; polystyrene (or Styrofoam) commonly used for disposable food containers; polyamide or nylon for toothbrush bristles and fishing lines; polyester for textiles. There are also special purpose plastics such as Teflon used in frying pans and water slides; polyurethane for insulation and upholstery foams; Bakelite insulation for electrical fixtures.

Despite all the advantages of using plastics, its threat on the environment has become increasingly intense since it degrades very slowly and when burned produces toxic fumes. Also, plastic production creates chemical pollutants which affect both the air and water and uses up the limited supply of fuel fossils. In order to alleviate the losses of the environment, it is always best to recycle plastics to either be used again to be re-processed into other products.

Building your own kennel unit is a very feasible project. By constructing one on your own, you can easily incorporate the necessary specifications that your pets need.  If you have the tools and armed with the right instructions, you can get started….

A dog kennel can be designed to follow the principles of convenience for you and comfort for your pets. These considerations will guide you to choosing the right materials, layout and design of the kennels.

With convenience in cleaning and maintaining the kennel in mind, you will be able to design the unit that will allow for ease in carrying out sanitation procedures. For example, plastic instead of wood for flooring. Steel is expensive and wood can splinter.  Plastic is affordable and easy to maintain and clean.  Also allows comfort for your pet.

Concrete may also be used for the base of multi-units, however lining with plastic sheets will allow for a cleaner kennel and easier maintenance, avoiding dealing with the cracks that can form from concrete and cause parasites to fester over time.

You can also customize the kennel to slope for better drainage. You can conveniently hose down dirt from the kennel compartments and not have to wipe or mop them clean. You can eliminate odor or keep it at minimum with more frequent disinfection.  The plastic isn’t porous and allows a slick surface to properly remove all feces and dirt.

Call us and talk about your options if you are interested!  We offer colors, too if you would like a little more flair in your kennel for your dog.

Plastic plays a crucial part in our current society. It’s everywhere – the most common material used to make products for our convenience – containers, cell phone casing, plastic bags, etc. Have you ever thought, for a moment, about the meaning of those symbols found in your plastic-made items?

Plastic recycling symbols show the forms of resin used to create the material. These representations are established following the international Plastic Coding System, and are customarily delineated as a number (from 1 through 7) enclosed by a triangle or a plain triangular loop (also known as the Mobius loop), with an acronym of the specific material used, right underneath the loop.

Here are succinct descriptions of each of the 7 recycling symbols frequently used, today:

1 – PET or PETE (Polyethylene Terephalate Ethylene)

Light weight, low-priced, and easy to fabricate, Polyethylene Terephalate Ethylene is the most prevalent plastic material in use today. PET is primarily used in beverage bottles, food receptacles, and peanut butter containers. It can be remade into polar fleece, fiber, carpet, etc. The requirement for this plastic among recyclers is relatively strong, but at present, the recycling rate for this material has remained low at 20%.

2 – HDPE (High Density Polyethylene)

High Density Polyethylene is more durable and more impervious to chemical degeneration, this material poses a relatively low chance of spreading chemicals when used as container for food and drinks. It is largely used as containers for everyday household chemicals (shampoos, degreasers, etc.), juice bottles, milk jugs, etc. This can be reused into floor tile, drainage, new HDPE bottles, pipes, etc.

3 – PVC (Polyvinyl Chloride)

PVC has been tagged as a health hazard – it has been noted to typically drain chemicals when used as containers. PVC is mainly used for piping, window cleaner bottles, siding, etc. It has chlorine and will dispense toxins if burned. PVC should not be used in food preparation or food packaging. It can be reprocessed into mudflaps, panels, mats, etc.

4 – LDPE (Low Density Polyethylene )

LDPE is the material present in plastic bags, clothing, furnitures, etc. Resilient and flexible, it is perfect for packaging, insulation, and sealing. LDPE, through many curbside recycling programs, can be reconstituted into cans, compost bins, and landscaping tiles.

5 – PP (Polypropylene)

Polypropylene is most suited for boiling fluid receptacles and is likewise made into brooms, straws, ketchup bottles, etc. PP can be reprocessed into rakes, brooms, trays, etc.

6 – PS (Polystyrene)

PS is the top component for insulation and is used in foam products like expanded polystyrene (EPS), commonly known as styrofoam. It is found in carry-out food containers, meat trays, CD cases. PS contains benzene, a cancer-causing substance and should not be burned. It is reprocessed into insulation, packaging, plant beds, etc.

7 – OTHER (Polycarbonate)

Recycling symbol 7 – OTHER signifies materials not belonging to any of the other 6 resin categories. OTHER may also signify a hybrid resin made up of a mishmash of those materials. It is mainly found in children feeding bottles, flak jackets, business signages, five-gallon water jugs, etc. It can be recycled into plastic planks and other tailor-made objects.

Not all number 7 plastics are polycarbonate, a handful are even plant-based. Polycarbonate has become the axis of dispute in recent years, as it is discovered to leach BPA (bisphenol A), a hormonal disruptor that may disastrously influence gestation and fetal growth.

Plastic recycling symbols are designed essentially to help the staff in recycling plants in properly segregating materials for processing. A rudimentary knowledge of these icons can also help us in ascertaining if the plastic item were handling at home are risk-free for us and our children.

In its simplest terms, the main difference between the different types of plastic is the way their cellular structure, or molecules bond with each other, and how tightly they are formed.

1) Low Density Polyethylene (LDPE), most common type of plastic sheeting, very flexible, most often from 0.5 mil thick to about 40 mil in flexible sheeting forms. Good conformability to surfaces. Because the cell structure is not as strong or dense as some other types of plastic sheeting, it is not typically as strong or puncture resistant as other forms or blends, but has thousands of common uses. Widely used for everything from construction and agricultural sheeting (often called Visqueen), Engineered Plastic Sheeting of countless types for such things as Vapor Retarders (also called Vapor Barriers by many), Surface Protection films, Pond and Canal Liners, Covers, Tarps, Abatement Plastic, Containment, packaging, and the list goes on.

2) Linear Low Density Polyethylene (LLDPE), blended form of LDPE where the film has much more flexibility, tensile strength, and more conformability. LLDPE is “softer” and more pliable, so is an excellent choice for such things as pond liners, or blended into other films to give them extra strength and flexibility. This is perfect for an application like a self-adhesive carpet protection film, where the film needs to have an amazing amount of strength in a very thin film to absorb impacts, but not tear or puncture. In this form of poly, the molecules all line up and strongly hold together as the film is stretched to give the structure much more strength and elongation than LDPE. Most common in thicknesses ranging from 0.5 mil to 40 mil in flexible plastic sheeting.

3) Medium Density Polyethylene (MDPE), the least commonly used form of polyethylene for flexible plastic sheeting. Has more strength than LDPE, a little more chemical resistance, tighter cell structure, more puncture and tear resistance. Often blended with LDPE and or LLDPE to give the attributes one is looking for in a particular type of film. For instance, many pond liners have MDPE to add some strength and toughness, without adding too much stiffness.

4) High Density Polyethylene (HDPE, aka HD), widely used for many applications. HDPE is the strongest, toughest, most chemical resistant, and least flexible of these four types of polyethylene. It also has the most UV resistance of the bunch without additive packages to increase this attribute. HDPE has a very tight cell structure, making it very difficult for other molecules to pass through its structure on a microscopic level. HDPE is the most easily field seamed of these products, and is generally used on an industrial level in thicknesses from about 12 mil to 100 mil thick. Most golf course ponds are lined with HDPE, most industrial ponds and canal liners, secondary containment liners, root barriers, many applications where chemical resistance is needed. This is also used in thousands or maybe millions of applications in thinner forms, especially in blends with the other types of polyethylene, because the HDPE adds much strength and toughness with its very tight bonds with other molecules.

The density of polyethylene is measured in a column of water, and they are all classified depending on ranges of density. LDPE (and LLDPE) are generally within the range of 0.919-0.924 g/cm³. MDPE are generally within the range of 0.926-0.940 g/cm³. HDPE are generally within the range of 0.941-0.965 g/cm³. These numbers can vary slightly depending on your source, and are not set in stone, just general guidelines.
