A class of thermoplastic terpolymers including a range of resins, all prepared with usually more than 50% styrene and varying amounts of acrylonitrile and butadiene. The three components are combined by a variety of methods involving polymerization, graft copolymerization, physical mixtures and combinations thereof. Typical applications are found in appliances, automotive parts, pipe, and business machine and telephone components.
Widely used plastic. It is a polymer of ethylene, CH2=CH2, having the formula (-CH2-CH2-)n, and is produced at high pressures and temperatures in the presence of any one of several catalysts, depending on the desired properties for the finished product. Polyethylene is resistant to water, acids, alkalies, and most solvents. Its many applications include films or sheets for packaging, shower curtains, unbreakable bottles, pipes, pails, drinking glasses, tubing, and insulation for wire and cable.
Plastic noted for its lightweight, being less dense than water; it is a polymer of propylene. It resists moisture, oils, and solvents. Since its melting point is 121°C (250°F), it is used in the manufacture of objects that are sterilized in the course of their use. Polypropylene is also used to make textiles, coating of wire and cable, packaging material, tubing, and trim molding.
Widely used plastic; it is a polymer of styrene. Polystyrene is a 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 marketed under the trade name Styrofoam. Its many uses include electrical and thermal insulation, translucent window and signage panels, storage-battery cases, toilet articles, and display signage.
Thermoplastic that is a polymer of vinyl chloride. Resins of polyvinyl chloride are hard, but with the addition of plasticizers a flexible, elastic plastic can be made. This plastic has found extensive use as an electrical insulator for wires and cables, tubing, gaskets, and trim molding.
A clear thermoplastic copolymer (copolyester) with high melt strength used mainly for profile extrusion. Provista/PETG is often used as a replacement for Acrylic due to cost and ease of processing. It has excellent chemical resistant and high clarity. It is also UV resistant and is FDA compliant for food contact applications. It’s many uses include display signage, tubing, trim molding, and clear window panels.
Diverse family of rubber like materials that, unlike vulcanized rubber can be processed like thermoplastic materials. TPE’s are used in a variety of applications in the automotive, construction, medical, food and beverage, electrical, appliance and electronic markets.
