Frequently Asked Questions (FAQ)

What are the primary applications of Kingflex colorful rubber foam sheets?

They are commonly used for insulation, cushioning, and protection. Specifically, they provide a lightweight, soft cover for padding objects and are widely utilized to insulate hot and cold water pipes to prevent condensation and heat loss.

What temperature range can this rubber foam sheet withstand?

According to the technical testing standard GB/T 17794-1999, the stable operating temperature range for the material is from -50°C to 110°C.

Does the product offer good fire safety ratings?

Yes. The product features highly rated fire-resistant properties, achieving Class 0 & Class 1 ratings when tested under BS 476 Part 6 & Part 7, and a flame spread/smoke developed index of 25/50 under ASTM E 84.

What is the advantage of the closed cell structure?

The closed cell design blocks water vapor penetration (permeability ≤0.91×10 ﹣¹³ Kg/(m.s.pa)), which dramatically slows degradation, prevents moisture buildup, and extends the long-term insulation life of the system.

What sizes and thicknesses are available for purchase?

Sheets come in thicknesses ranging from 1/4" (6mm) up to 2" (50mm). Roll options are available in standard widths of 1m, 1.2m, and 1.5m to fit various industrial or residential project needs.

Is the insulation material resistant to environmental factors like UV and ozone?

Yes, technical evaluations show the foam has "Good" rating levels for fungi resistance (ASTM 21), ozone resistance (GB/T 7762-1987), and resistance to UV and weathering (ASTM G23).
