BURRELL INSULATION MATERIAL
BURRELL BSC1 / BTC1 Insulation Material uses NBR (nitrile-butadiene rubber)as main raw material for foaming and become a fully closed cell of flexible rubber insulation materials, without any fiber materials, HCHO and CFC which are bad for the ozonosphere. It is black material with excellent product performance, make the products be widely used in various public places, industrial workshop, clean room and medical education institutions, petrochemical industry etc.
BURRELL BSC1 / BTC1 Sheet / Tube Insulation Material Performance Characteristics
LOWER CONDUCTIVITY
Burrell Insulation Material comprehensively adopted the most advanced international "nano" foaming technology,100% full cell, well distributed small cell structure, very low conductivity λ≦0.033w/(m.k) at 0℃ .
HIGHER MOISTURE RESISTANCE
Burrell Insulation Material is of cell structure, excellent ability of water vapor permeability, moisture resistance μ≧10000, make materials become both of moisture proof layer and thermal insulation layer, so as to ensure the long-term stability of the material properties, around 15 years life time.
HIGH SECURITY FIRE PREVENTION FUNCTION
We adopt special environment protecting formula without any halogen, and the fireproof medium well distributed in every cell structure. No unhealthy gas while burning, which is in accordance with national new standard Class B in the GB 8624-2012. In the mean time,good performance in the smoking, burning drops and gas toxicity, which is the most reasonable insulation material for our customers.
