expanded plastic

The Company's product range includes granite overburden goods, expanded plastic goods and community services.

Sponges are always synthetic and are usually made from polyurethane foam or similar expanded plastics.

Some manufacturers have started using a new, significantly more environmentally friendly alternative to expanded plastic packaging made out of paper, known commercially as paperfoam.

Expanded plastics, foams and vinyls however are generally candidates for routing rather than laser engraving.

The packaging has very similar mechanical properties to some expanded plastic packaging, but is biodegradable and can also be recycled with ordinary paper.

In addition to their use as refrigerants, CFCs have been used as propellants in aerosol cans, cleaning solvents for circuit boards, and blowing agents for making expanded plastics used as packaging materials.
