A: The rubber foam insulation achieves Class 0 & Class 1 fire ratings according to BS 476 Part 6 and Part 7. It is self-extinguishing and produces no drips under the ASTM D635-91 testing standard, making it highly secure for various piping environments.
A: It is highly energy-efficient, featuring a low thermal conductivity rating of ≤0.034 W/m.K. Specific tests under ASTM C 518 show thermal conductivity ratings as low as ≤0.030 W/(m.k) at -20°C and ≤0.032 W/(m.k) at 0°C, providing exceptional thermal retention and energy savings.
A: Yes, it is eco-friendly. The material contains no dust or fibers, is entirely CFC-free, and emits low VOCs. It is also highly resistant to moisture, supporting negligible bacterial growth and zero fungal growth (complying with ASTM 21 standards).
A: Absolutely. Thanks to its highly flexible physical properties, the rubber foam is easy to bend, shape, and cut. This makes it ideal for irregular pipelines, elbows, and fittings, saving significant time, labor, and excess material costs during installation.
A: Roll thicknesses range from 1/4" (6mm) up to 2" (50mm). Standard rolls are available in widths of 1m, 1.2m, and 1.5m, with varying lengths to accommodate different project requirements and maximize coverage efficiency.
A: Yes, the rubber foam can be customized in various colors, including red, blue, green, grey, and yellow. This assists with color-coding different service lines, resulting in cleaner aesthetics and easier system maintenance.
