Frequently Asked Questions (FAQ)
Q1. What are the primary applications of this flexible insulation material?

This high-quality elastomeric foam is primarily designed for insulation in the heating, ventilating, air conditioning, and refrigerating (HVAC & R) sectors. It effectively prevents heat gain or loss in chilled water systems, hot and cold water plumbing, refrigerated pipelines, and air conditioning ducts.

Q2. What is the temperature range resistance of the elastomeric foam?

The insulation material functions exceptionally well across a temperature range of -50°C to 110°C, verified in compliance with the GB/T 17794-1999 test standards.

Q3. Does this insulation product meet safety standards for fire rating?

Yes, the material achieves Class 0 & Class 1 fire ratings according to BS 476 Part 6 & 7. Additionally, it has a Flame Spread and Smoke Developed Index of 25/50 under the ASTM E 84 standard.

Q4. How does the product handle moisture and water absorption?

Thanks to its closed-cellular structure, the material features an extremely low water vapor permeability (≤0.91×10 ﹣¹³ Kg/(m.s.pa)) and maintains water absorption of only 20% by volume as tested by ASTM C 209, ensuring robust protection against moisture ingress.

Q5. How durable is the insulation against outdoor environmental factors?

It features strong resistance capabilities, graded as "Good" for ozone resistance (GB/T 7762-1987), UV and weather resistance (ASTM G23), and fungi resistance (ASTM 21), ensuring longevity under tough environmental conditions.

Q6. What sizes and thicknesses are available for installation?

The thickness ranges from 1/4" (6mm) up to 2" (50mm) to support varying thermal needs. It is available in roll widths of 1m, 1.2m, and 1.5m with customized roll lengths depending on the specifications.
