Polyolefin foam materials are based on polypropylene or polybutylene polymer materials and have countless bubbles inside, also considered a composite material with gas as filler. We adopt advanced continuous polymerization method to ensure the product quality and the complete offering. The products are mainly applied in packaging, leisure goods, refrigeration, construction, auto, and other fields.
1. This kind of foam material is lightweight, has good elasticity, anti-vibration and anti-pressure features, and a high deformation recovery rate;
2. Oil resistance, acid resistance, alkali resistance, resistance to various chemical solvents, non-absorbent, insulating;
3. Good heat resistance (polypropylene -40 ~ 130C / polybutylene -40 ~ 110°C.
Packaging, leisure goods, refrigeration, construction, auto, and other fields.
