PVC/Nitrile (NBR) Sponge Rubber
When PVC and Nitrile are combined by polymerisation, they product is a soft, closed cell sponge rubber which needs a low deflection force to create a seal.
Properties
Excellent resistance to acid, fuel & oil, Density: 60 – 90 Kg/m³SoftPoor compression setOzone resistantTemperature range from +85°C to - 50°C. Fire Retardant to BS476 pt. 6 & 7 Class O.Typical Uses:
Oil Seals, Cushioning, Vibration Dampening Shock AbsorptionPipe LaggingThermal InsulationConstruction ApplicationsMedical ApplicationsThe foams can be supplied with or without a self adhesive backing and can be cut into coils for sealing tapes.
Super-Soft PVC/Nitrile Sponge Rubber
A new semi-closed cell version has been developed as an alternative to Nitto and Armacell grades. The product is a standard PVC/Nitrile sponge rubber and the cells have been crushed to open some of them up to create a soft low compression seal product.
Properties:
Density is approx. 90 Kg/m³Excellent Air & UV resistancePoor oil resistanceGood Acid resistanceUltra soft with little compression required to deform it.Typical Uses:
Sealing of Air Conditioning DuctsAreas for superior water tightnessInstrument panel mountingWindscreen mountingMirror mountingCentre Pillar MountsSeals where uneven surfaces are presentNBR foam sheet is a high quality flexible insulation product designed for insulating in the field ot heating,ventilating,air-conditioning and refrigerating on the basis of the elastomeric foam with closed-cell structure. Kingwell provides efficient method of preventing undersirable heat gain or loss in chilled water systeml,cold and hot water plumbing,refrigerated pipes,air-conditioning ductwork and equipment. | ||||
