Frequently Asked Questions
What are the main raw materials used in this thermal insulation?
The material is produced from high-performance nitrile rubber (NBR) and polyvinyl chloride (PVC) as the main ingredients, manufactured via advanced sulfuration and foaming processes.
What is the safe operating temperature range for this insulation?
This rubber foam thermal insulation has an effective operating temperature range of -50°C to 110°C, tested in compliance with the GB/T 17794-1999 standard.
How does the closed-cell structure benefit the application?
The closed-cell structure creates a highly effective built-in barrier that prevents water vapor penetration. This keeps the material dry and significantly prolongs the service lifespan of the system.
What fire ratings does the insulation material achieve?
The insulation meets Class 0 and Class 1 standards according to BS 476 Part 6 & Part 7, offering excellent flame retardancy and high safety performance.
What roll dimensions and thicknesses are available?
Standard thicknesses range from 1/4" (6mm) up to 2" (50mm). Standard roll widths are available in 1m, 1.2m, and 1.5m to suit different engineering installation requirements.
