Plastics & Polymers

Why do thermoformed packaging such as blister packs typically end up in landfills, even though many of them are made of PC PET?

Designers should not forget the end user

Injection molding small and microscopic parts can involve different requirements than those cited by manufacturers. Micromolder Accumold tested various resins in a standard mold to see how they performed.

The TPI resin works in injection-molding and extrusion processes.

Vacuum-formed plastics replace real items in film and stage sets

Vacuum-formed architectural elements and props from Provost Displays use a Boltaron sheet to imitate the look of real items while maintaining paintability, impact resistance, and recyclability.

The compounds have 10 to 40% glass-fiber reinforcement.

The foams are intended for sealing and shock absorption in handheld-electronics applications.

The promoter helps parylene coatings bond to polyimide and other plastics.

The impact modifier works in injection-molding operations.

The laminated sheet is optimized for form-fill-seal operations.

The washers and spacers come in a variety of materials, ODs, IDs, and thicknesses.

The sheets are designed for stadium construction.

The welders are designed for medical applications.

Holsters for military, law-enforcement, and recreational use are thermoformed from a laminated thermoplastic-core composite that resists temperature extremes, fires, and impacts.

Injection-Molding Liquid-Crystal Polymers

Liquid-crystal polymers suit the injection molding of micro and thin-wall designs.
