Introduction
rubber foam insulation sheets are totally formaldehyde-free,CFC-free and can be directly exposed to the air, not harm for human health. In order to form high closed cellular rate and low thermal conductivity foam insualtion sheets, we choose NBR which is no harm to the environment as our main material and other good quality materials and use vacuum extrusion ,accurate temperature control foaming process .
