Frequently Asked Questions
What are the fire ratings for this insulation material?
The material achieves Class 0 and Class 1 fire ratings, meeting BS 476 Part 6 & Part 7 test standards. It has a Flame Spread and Smoke Developed Index of 25/50 under ASTM E 84.
What forms of insulation products are available?
The insulation comes in three main formats: extruded flexible tubes (designed for standard copper, steel, and PVC piping), rolls, and sheets (available in pre-cut sizes or rolls).
What is the operating temperature range?
The operating temperature range is -50°C to 110°C, tested in compliance with the GB/T 17794-1999 standard.
How does the material prevent moisture absorption?
Thanks to its closed pore foaming structure, the insulation material has a high water vapor resistance factor (μ ≥ 10000) and a low water absorption value of 20% by volume (ASTM C 209).
Is this insulation material environmentally and health-safe?
Yes. The material is safe to handle and install. It does not stimulate or irritate the skin, does not harm health, and is resistant to fungi, ozone, and UV weathering.
