CIP Composites CIP252A

CIP Composites CIP252A is a proprietary material made specifically for marine environments. Typically used as propeller shaft and rudder bushings and is recommended in sand and silty environments. Manufactured with polyester and PTFE combined textile and a high grade marine polyester resin with the solid lubrication additives PTFE and molybdenum disulfide (MoS2) evenly dispersed throughout the resin. This combination of resin reinforced with textile creates a dimensionally stable material ideal for replacing bronze in marine environments.
