Frequently Asked Questions (FAQ)
Q: What is the base material of these insulation sheets?
The sheets are made of premium synthetical rubber with a closed-cell structure, ensuring excellent thermal insulation and moisture resistance.
Q: What is the operational temperature range?
These insulation sheets are designed to perform reliably within a wide temperature range of -50°C to 110°C, suitable for both low-temperature refrigeration and heating systems.
Q: Are these sheets fire-resistant?
Yes, the insulation material has a Fire Rating of Class 0 & Class 1 (tested to BS 476 Part 6 & 7) and an Oxygen Index of ≥36.
Q: Can they be used on large surfaces and complex pipe fittings?
Absolutely. The sheets are specifically designed for insulating very large surfaces, metal sheet pipes, plenum boxes, and complex pipe fittings, and they are available in a self-adhesive format for easy installation.
Q: How do they perform against environmental factors like U.V. and ozone?
They offer outstanding durability with rated "Good" resistance to fungi (ASTM G21), ozone (GB/T 7762-1987), and U.V./weathering (ASTM G23).
