摘要: Wearable rubber parts for fluid handling systems include a four layer structure, wherein the inner most layer of the four layer structure is a polyurethane layer. The polyurethane can be millable polyurethane. The polyurethane used in the inner most layer can be produced by reacting diisolcyanate with a polyester and/or polyether polyols and a chain extender. The wearable rubber part can be an expansion joint, a pinch valve, or a hose.
