Polypropylene (PP)
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.

Polystyrene (HIPS)
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.

Polyvinyl chloride (PVC)
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.

Provista/PETG
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.
