Thermal & Sound Insulation

Oxide-Acetete Foam

Oxide-acetete foam is specially developed for extra softness, high flame retardance, and weather resistance. The blend combines the mechanical strength of XLPE with the softness of nitrile rubber, producing a closed-cell, soft, and flexible insulation that performs as both a thermal and an acoustic barrier across a wide service window from -40 to +120 °C. It is UV resistant, naturally resists fungal, bacterial, and mould growth, and meets stringent fire-safety standards including BS 476 Part 7 Class 1 surface spread of flame, BS 476 Part 6 Class O fire propagation, and the IMO MSC 307(88) smoke and toxicity index. Typical applications include hot and cold chilled water piping, HVAC ducting, glass spandrel insulation, and under-deck RCC and metallic roofing.
