Chemical Classification of Plastic Materials

Plastic material is one the most used industrial products that has its application in the multiple areas. In this article some of the major types of Plastic is discussed in terms of Chemical Classifications.

Also for each chemical formulae and its application is also described.  Plastic material provide the advantage that it can be recycled making it material whose stock pile should not be compiled .

1- PETE – Polyethylene Terephthalate :

Polyethylene Terephthalate (PET, PETE) is transparent, rough, has good quality provides feature of damped barrier which make it to be ideally be used for those areas where there is a need for  dirt free environment. Are you looking  acrylic plastics in Adelaide? You can contact Not only new PETE material is used but in the market recycled PET flakes and pellet are in vast demand which are used for spiraling fiber for carpet yarns, Manufacturing fiberfill & geo-textiles. One interesting application is that Fiber prepared by PETE is known as polyester.


Disposable bottle for soft drinks, water, fruit juice, sports diet drinks, mouthwash, catsup and ready to eat vegetable dressing, foodstuff jars for peanut butter, jelly, jam and pickles. Oven heat proof plastic films & microwavable foodstuff trays. In adding to wrapping, PET’s main uses are also in areas of textiles, monofilament, carpet, fastening, film & engineering moldings.

Re-Cycled PETE is made up into:

Fiber for carpeting, fleece coats, comfort filling and tote bags. It may also be cast-off into containers for food stuff, drinks pots & non-food objects.

2 – HDPE – High density Polyethylene

High Density Polyethylene (HDPE) is applied to formulate many kinds of bottles. Bottles are mainly used in food packaging industry , they are not pigmented ,  semi-transparent, have fine barrier against external pressure, higher rigidity & are fit well-matched to packaging goods by a short shelf life for e.g. milk. For the reason that HDPE has superior chemical resistance, it is used in packaging of household and industrialized purpose chemicals like detergents and peroxides.


Plastic bottles containing milk, water and other drinkables, cosmetic, hair-shampoo, bowl and laundry detergents plus domestic cleaners. Baggage for groceries & retail buying. Cornflakes box liners, Re-usable transport containers. In addition to packaging, HDPE’s application is also in injection molding functions for the manufacturing of extruded pipe & tool, plastic wood composites, wire and cable jacketing.

Application Areas:

Jugs for uneatable items, for example shampoo, hair-conditioner, liquid detergent for laundry, domestic cleaners, engine oil and antifreeze. Artificial lumber for out-door decoration, fencing and vocational picnic tables. Pipe, flooring tiles, buckets, birdcages, flower pans, gardening plot binding, film & sheet and recycling baskets.

3 – LDPE Low-density Polyethylene

Low Density Polyethylene (LDPE) is utilized predominately in film usage due to its stiffness, elasticity and relative clearness; making it admired for use in applications wherever heat sealing is essential. Moreover LDPE is used to produce some plastic covers and pots as well as in lead & cable applications.

Newspapers, bread, household garbage, frozen food stuffs, and hand baggage for dry cleaning. Shrink enfold and stretch film. Coverings for paper milk packets & hot and icy drink cups. Container tops. Toys, Press able bottles (for e.g. honey and mustard).

Recycled LDPE Application Areas :

Delivery envelopes, trash can liners, floor tile, paneling, furniture stretched protective sheet, film and sheet for other purpose, muck bins, trash cans.

4 – PVC – Polyvinyl Chloride

This material is mostly used for plastic manufacturing .Polyvinyl Chloride (PVC, Vinyl) has first-rate chemical retaliating, flow attributes & steady electrical functions. Products prepared from Vinyl can be both stiff and stretchy.
