PR0DUCT INTRODUCTION
We produce RUbber-plsatic Foamed Heat Preservation Products(PVC/NBR)by introducing newest technology and craft and automatic processing line.The major materials we use are NBR/PVC,which are undergone ban bury,vulcanization and foam,Therefore,the main characteristics are:Low density,close bubble structure,low thermal conductivity,
Water vapor transmissibility extremely low,low water -absorptive ability,Fire-proof performance well,superior anti-agde performance,good flexibility,easy to install.
This product is suitable for a wide temperature range,from -40℃ is to 105℃ ,also has good anti-adge performance and durability.Its fire +proof capacity achieves the standard of national B1 level.
