The main raw material is nitrile rubber, which is foamed into a highly flexible rubber-plastic heat-insulating material featuring a completely closed bubble structure.
This material is rated to perform safely and efficiently across a temperature range of -50°C to 110°C, tested in compliance with GB/T 17794-1999 standards.
The material achieves a Class 0 & Class 1 Fire Rating according to BS 476 Part 6 & 7 standards. It also meets the ASTM E 84 standard with a Flame Spread and Smoke Developed Index of 25/50.
Yes, it features a water vapor permeability of ≤0.91×10 ﹣¹³ Kg/(m.s.pa) and excellent resistance to fungi, ozone, ultraviolet (U.V.) light, and weathering.
Yes, the closed-cell rubber structure provides excellent acoustic insulation, which effectively absorbs reverberating sounds and reduces sound transmission within buildings.
