NBR/PVC is a polymer blend that combines nitrile butadiene rubber (NBR) and polyvinyl chloride (PVC) to achieve a balanced set of physical and chemical properties that neither material can provide alone.
NBR is known for its excellent resistance to oils, fuels, and many chemicals, while PVC offers strong resistance to ozone, sunlight, heat, and weathering. When blended, they produce a durable, weather-resistant material that retains good flexibility even at low temperatures.
NBR/PVC also exhibits better flame resistance than NBR alone and features low gas permeability, making it suitable for applications requiring fluid and gas leakage prevention.
The blend’s formulation can be custom-compounded to enhance specific properties such as higher flame retardancy, abrasion resistance, or elasticity. This versatility makes NBR/PVC suitable for a wide range of applications, including the automotive industry (seals, gaskets, fuel hoses), cable industry (oil- and flame-resistant cable sheathing), construction sector (waterproof and chemical-resistant seals), and various outdoor equipment exposed to harsh environments.
