List of Plastic Materials and Properties

	apperance	property	products
Acrylonitrile butadiene styrene (ABS)	Shiny, impervious surface, used to make light, rigid, molded products.	Resistant to aqueous acids, alkalis, concentrated hydrochloric and phosphoric acids, alcohols and animal, vegetable and mineral oils. Soluble in esters, ketones and ethylene dichloride. Flammable when it is exposed to high temperatures, will "boil", then burst spectacularly into intense, hot flames.	Musical instruments, golf club heads (used for its good shock absorbance), automotive body parts, wheel covers, enclosures, protective head gear, cosmetic bottle jar.
Polyacrylates (Acrylic)	High polish, clear & colorless, transparent to visible & ultraviolet light.	Can be shaped while hot to form a number of objects	Widely use transparent objects such as cosmetic container: cream jar & bottle, display frame, holder.
Polyethylene Terephthalate (PET/ PETE)	Naturally colorless and transparent.	PET can be semi-rigid to rigid, depending on its thickness Lightweight. It makes a good gas and fair moisture barrier, as well as a good barrier to alcohol (requires additional "Barrier" treatment) and solvents. It is strong and impact-resistant.	PET is often coated with aluminium to reduce its permeability, and to make it reflective and opaque. PET bottles are excellent barrier materials and are widely used for soft drinks bottle, drinking bottle, cosmetic container: jar, shampoo bottle, sprayer bottle, travelling kit sets, medicine bottle, microwavable packaging.
Polyester		Any of numerous synthetic polymers produced chiefly by reaction of dibasic acids with dihydric alcohols and used primarily as light, strong, weather-resistant resins in boat hulls, textile fibers, adhesives, and molded parts. A wrinkle-resistant fabric of fibers made from any of these resins. polyester fibers are formed from a chemical reaction between an acid and alcohol. In this reaction, two or more molecules combine to make a large molecule whose structure repeats throughout its length. Polyester fibers can form very iong molecules that are very stable and strong.	The fabric is easily dyeable, and not damaged by mildew. Textured poly-ester fibers are an effective, nonaller-genic insulator, so the material is used for filling pillows, quilting, outerwear, sleeping bags, bottle holder, plastic bottle chips, pills bottle, recycle bags, cosmetic bottle, cooler bag, water bottle.
Polyethylene (PE)		Cheap, flexible, durable, and chemically resistant, high elastic and able to form with different density: HDPE, LDPE, MDPE	Wide range of inexpensive uses including supermarket bags, plastic bottles, and cosmetic tubes or squeezing bottles. HDPE: High Density Polyethylene Commonly found on: detergent bottles, milk jugs. HDPE is used for containers, plumbing, and automotive fittings.LDPE: Low Density Polyethylene - Commonly found on: dry-cleaning bags, produce bags, trash can liners, food storage containers. LDPE is used to make films and packaging materials that is squeezable.
Polypropylene (PP)		A tough material having good resistance to heat and chemical action. It can used in the manufacture of objects that are sterilized in the course of their use. Its light weight, being less dense than water; it is a polymer of propylene. It resists moisture, oils, and solvents.	Polypropylene is also used to make textiles, ropes that float, packaging material, and luggage. Commonly found on: cosmetic bottle caps, tubes & bottles, drinking straws, food containers.
Polystyrene (PS)		Colorless, transparent thermoplastic that softens slightly above 100°C (212°F) and becomes a viscous liquid at around 185°C (365°F). It is resistant to acids, alkalies, oils, and alcohols. It is produced either as a solid or as a foamed plastic.	Packaging foam, food containers, disposable cups, plates, cutlery, CD, cassette boxes, cosmetic jar, cosmetic holder, cosmetic packaging tray, bottle cap, cosmetic bottle, medicine bottle. Its many uses include electrical and thermal insulation, translucent window panels, storage-battery cases, and toilet articles.
Acrylonitrile Styrene (AS)		High density material which is elastic and against pressure	Cosmetic bottle, cap & cream jar, drinking bottle
Polyvinyl Chloride (PVC)		Insoluble in most organic solvents, inexpensive nature and flexibility.	Used in soft flexible films for food packaging and in molded hard or rigid products such as pipes, fibers, cosmetic jar and bottle.
