Frequently Asked Questions
What are the primary materials used in this rubber foam insulation?
The major raw materials used in the production process are premium NBR (Nitrile Butadiene Rubber) and PVC (Polyvinyl Chloride).
What is the thermal conductivity of this insulation material?
The material features an exceptionally low thermal conductivity: ≤0.030 W/(m.k) at -20°C, ≤0.032 W/(m.k) at 0°C, and ≤0.036 W/(m.k) at 40°C, complying with ASTM C 518 standard.
How does this product perform in terms of fire resistance?
It meets Class 0 and Class 1 fire ratings according to BS 476 Part 6 & 7, with a high oxygen index of ≥36 (GB/T 2406, ISO4589) and a flame/smoke index of 25/50 (ASTM E 84).
What is the applicable temperature range for this insulation?
This rubber foam insulation is designed to operate effectively within a temperature range of -50°C to 110°C, tested under the GB/T 17794-1999 standard.
How does the material prevent moisture penetration?
Due to its closed-cell foaming structure, the material has low water vapor permeability (≤0.91×10 ﹣¹³ Kg/(m.s.pa)) and high water vapor resistance factor (μ ≥10000), offering outstanding damp-proof performance.
Is this product safe for installation and environment resistant?
Yes. It is completely safe as it does not stimulate the skin or harm health. Additionally, it offers excellent resistance against fungi, ozone, ultraviolet (U.V.) rays, and outdoor weathering.
