PU70BK00 is Canyon’s general-purpose 70 Shore A black CanThane polyurethane (PU) engineered for O-rings, gaskets, and molded sealing components that demand excellent wear and tear resistance. This polyether gum polyurethane delivers outstanding abrasion resistance with good flexibility and compression set performance, supporting reliable sealing in static and light dynamic applications. With a service temperature range of -55°C to 110°C (-67°F to 230°F), PU70BK00 maintains toughness and elasticity while resisting water, oxygen, ozone, and weathering. Its balanced mechanical properties make it a practical choice where durability and longevity are prioritized over broad chemical compatibility. Compare PU70BK00 to Parker P0642-70 for similar 70 Shore A polyurethane sealing performance.
PU70BK00 is commonly used in industrial equipment, power transmission components, and wear-prone sealing interfaces where elastomer life is limited by abrasion. The material’s high tensile strength and elongation support repeated deformation without tearing, helping reduce maintenance and downtime. Canyon Components offers PU70BK00 as a cost-effective polyurethane option for demanding wear environments in O-rings and gaskets.
