Quality Insulation
NBR/PVC Closed Cell Foam Pipe Insulation Material
WS class 1 NBR Sheet
Plate structure,
with nitrile butadiene rubber as the main raw material by foaming,
with completely closed foam flexible rubber plastic insulation material.
Test method: flame extension range ≤165mm when 1.5 minutes,
flame extension range ≤165mm when 10 minutes.
Introduction
Mainly NBR/PVC as the main raw material, cooperate with flame retardant agent, foaming agent, curing agent, promoter and stabilizer, strengthening agent, such as additives, end spacing, mixing, extrusion, curing, foaming, cooling, cutting and become, has a small independent closed pore structure, heat preservation performance is good, good compression resilience, strong ability to resist water vapor permeability, good fireproof performance, low smoke non-toxic, Safe and reliable, long service life.Better thermal insulation effect
initial thermal conductivity of 0.032W (M.K) 0ºC rubber plastic adopts a special formula process, has a completely closed bubble internal structure, lower thermal conductivity is more stable, long-term operation energy saving effect is obvious.
