ABS Plastic

Acrylonitrile Butadiene Styrene (ABS) is a common thermoplastic. ABS combines the strength and rigidity of acrylonitrile and styrene polymers with the toughness of polybutadiene rubber. While the cost of producing ABS is roughly twice the cost of producing polystyrene, it is considered superior for its hardness, gloss, toughness, and electrical insulation properties.

ABS’s light weight and ability to be injection molded and extruded make it useful in manufacturing products such as drain-waste-vent (DWV) pipe systems, musical instruments (recorders, plastic clarinets, and piano movements), golf club heads (due to its good shock absorbance), automotive trim components, automotive bumper bars, medical devices for blood access, enclosures for electrical and electronic assemblies, protective headgear, whitewater canoes, buffer edging for furniture and joinery panels, luggage and protective carrying cases, small kitchen appliances, and toys, including Lego bricks.

PVC

Polyethylen Teraphthalat ( PET ) is commonly used for carbonated beverage, water bottles and many food products. PET provides very good alcohol and essential oil barrier properties, generally good chemical resistance (although acetones and ketones will attack PET) and a high degree of impact resistance and tensile strength. The orienting process serves to improve gas and moisture barrier properties and impact strength. This material does not provide resistance to very high temperature applications—max. temp. 200 °F

PVC

Polyethylene (abbreviated PE) or polythene (IUPAC name polyethene or poly(methylene)) is the most common plastic. The annual global production is approximately 80 million tonnes. Its primary use is in packaging (plastic bag, plastic films, geomembranes, containers including bottles, etc.). Many kinds of polyethylene are known, with most having the chemical formula (C2H4)n. Thus PE is usually a mixture of similar organic compounds that differ in terms of the value of n.

Polycarbonate

This material is formed by a condensation polymerization resulting in a carbon that is bonded to three oxygens. The most common system for this polymerization is formed by a reaction of bisphenol A and phosgene. Applications of polycarbonate are almost always those which take advantage of its uniquely high impact strength and its exceptional clarity. These unique properties have resulted in applications such as bulletproof windows, break resistant lenses, compact discs, etc.

Some other usage of PC are: Electrical/Electronic Applications, Automotive Applications, General Purpose, Medical/Health-care Applications, Housings, Appliances, Sporting Goods, Business Equipment, Industrial Applications, Electrical Parts.

Polypropylene

It is used in a wide variety of applications including packaging and labeling, textiles (e.g., ropes, thermal underwear and carpets), stationary, plastic parts and reusable containers of various types, laboratory equipment, loudspeakers, automotive components, and polymer banknotes. An addition polymer made from the monomer propylene, it is rugged and unusually resistant to many chemical solvents, bases and acids.

Polystyrene

Eggs and dairy products, meat, fish and poultry, cold drinks or carry-out meals. All these products are safely packed with polystyrene packaging materials; by doing so spoilage of foods is prevented.

From refrigerators and air conditioners, to ovens and microwaves, from hand-held vacuum cleaners to blenders, polystyrene resins meet almost all end-product requirements. Polystyrene resins are safe and cost effective, with excellent appearance and functionality mainly due to easy-processing. Because of this almost 26 percent of the polystyrene demand is used in injection-molding, extrusion and thermoforming applications.

Some other usage of PS are in: Consumer Electronics, Construction, Medical, others.
