Air Bubbles & Polyethylene Foam

Air Bubbles
Air bubbles is made of typical polyethynene bubble warps sandwiched bettween two layers of pure aluminum. The light silver surfaces reflect radiant heat while the bubbles prevent heat conduction and support fast hear emittance. Besides, the bubble waps system sound wave, simultaneously get rid of reflective sound wave due to the hill surfaces and unstable shapes.

Polyethylene Foam

Polyethylene foam a is elastic product consisting all properties: thermal insulation (with three modes: blocking heat, reflecting 97% radiant heat, convection heat), noise insulation, strong, nice... It is produced from polymerization processing and MDI as main ingredients, they have closed cell structure. Dinemsion of closed cell is very small and this leads to excellent thermal and sound insulation, negligible water absorption. This closed cell have more outstanding thermal insulation properties in comparison with glasswool, air bubbles, vulcanized rubber or other insulation.
