Product Description
Diamond pattern flame retardant sponge tube features concave-convex diamond grid outer surface, combining anti-slip performance and ultra-high abrasion resistance. The special grid structure disperses friction pressure, effectively extend service life under heavy wear conditions, the best choice for outdoor semi-open facilities and high-friction equipment frames.
Made of high-density flame retardant PVC cellular foam, this product passes national B1 flame retardant test and international UL94 fire safety standard, with outstanding anti-aging, anti-oxidation, UV weak resistance and waterproof performance. The diamond grid surface is breathable, not easy to retain water and sweat, avoid mildew even in damp environment.
We can customize foam density, tube wall thickness, inner and outer diameter, length and color for diamond pattern foam tubes. The product has stable compression resilience, will not deform after long-term extrusion, factory direct wholesale with competitive price for playground, fitness and engineering bulk orders.
