Frequently Asked Questions

Q1: What are the main raw materials used in this rubber foam insulation?

A1: This material is manufactured using high-quality polyvinyl chloride (NBR, PVC) as the primary raw materials, blended with auxiliary materials through a specialized foaming process on an automated continuous production line.

Q2: What is the applicable temperature range for this insulation material?

A2: The insulation is designed to operate effectively within a temperature range of -50°C to 110°C, tested in compliance with standard GB/T 17794-1999.

Q3: How does the closed-cell structure benefit the performance of the insulation?

A3: The closed-cell structure acts as a reliable barrier against water vapor penetration. This prevents moisture accumulation inside the material, ensuring stable thermal performance and extending the overall service life.

Q4: What is the fire rating and safety performance of this rubber foam?

A4: The product achieves a Class 0 and Class 1 fire rating according to BS 476 Part 6 & 7. It has a Flame Spread and Smoke Developed Index of 25/50 (ASTM E 84) and an Oxygen Index of ≥36 (GB/T 2406, ISO4589), ensuring high safety performance.

Q5: Is this rubber foam resistant to mold, UV, and outdoor weather conditions?

A5: Yes, the material offers good resistance to fungi (ASTM 21), ozone (GB/T 7762-1987), and UV/weathering (ASTM G23), making it highly durable under tough environmental conditions.

Q6: Is it easy to install this material on complex pipeline shapes?

A6: Yes, the material is highly flexible, making it ideal for covering curves, bends, and irregular structures easily. This flexibility ensures a seamless fit and simple installation.
