McDunnough, Inc. Provides Polyester (PET) Plastics

Polyester (PET) Plastics
The unsaturated polyesters are extremely versatile in terms of the forms in which they are used. Polyester resins can be formulated to be brittle and hard, tough and resilient, or soft and flexible. In combination with reinforcements such as glass fibers, they offer outstanding strength, a high strength-to-weight ratio, chemical resistance, and other excellent mechanical properties. The two dominate materials in this plastics family are polyethylene terphthalate (PET) and polybutylene terephthalate (PBT). The thermoplastic polyesters are similar in properties to types 6 and 6/6 nylons, but have lower water absorption and higher dimensional stability than the nylons.
PET - Polyethylene terephthalate is a water-white polymer and is made into fibers, films and sheets, and blow-molding and thermoformed containers for soft drinks and foods. Glass reinforced PET compounds can be injection-molded into parts for automotive, electrical/electronic, and other industrial and consumer products.
