Class 1 Closed cell rubber closed cell thermal insulation adopts advanced ACMF technology, utilizing acrylonitrile-butadiene rubber as the main raw materials to form a flexible, closed-cell structured insulation.
This thermal insulation is composed of acrylonitrile-butadiene rubber as the primary raw material. It uses advanced ACMF technology to form a high-performance, flexible closed-cell structure.
The insulation operates reliably within a wide temperature range of -50°C to 110°C, tested in compliance with GB/T 17794-1999 standard requirements.
The material achieves Class 0 & Class 1 fire ratings according to BS 476 Part 6 and Part 7 tests. It also has a Flame Spread and Smoke Developed Index of 25/50 under ASTM E 84, alongside an oxygen index of ≥36.
It possesses excellent moisture resistance with a water vapor permeability factor (μ) of ≥10000. Additionally, it shows good resistance to fungi growth (ASTM 21), ozone (GB/T 7762-1987), and weather/UV exposure (ASTM G23).
The insulation is available in thickness levels ranging from 1/4" (6mm) to 2" (50mm). Roll widths are offered in 1m, 1.2m, and 1.5m variants, with corresponding lengths to meet different design specifications.
It features exceptionally low thermal conductivity across multiple temperatures, showing ≤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, tested under ASTM C 518.
