HyComp H310™

H310™

H310 is an aerospace-grade blend of high-temperature resin thermoset polymer sheet molding compound (SMC) with one-inch chopped carbon fiber reinforcement. It has the highest strength of the Saint-Gobain HyComp materials at temperatures up to 600°F and is best for lower speeds and high loads.

Applications vary from bushings, guide rings, wear liners, seals, clamps, and thermal isolators.

H320™

H320 is a blend of a high temperature thermoset polymer and 1” glass fiber. This unique combination provides the highest strength at temperatures up to 600°F.

This material is best suited for high temperature heat shields and high temperature electrical insulation applications.

WearComp®

WearComp®

WearComp is a blend of a high temperature polymer and 1” chopped carbon fiber. This unique combination provides a low coefficient of friction, outstanding mechanical strength, and wear resistance at temperatures up to 600°F.

WearComp is particularly suited to liner and bearing sleeves, and sliding plates subject to high stresses.

 

WearComp® 200

WearComp® 200

WearComp 200 is a blend of a high temperature polymer and 1” chopped carbon fiber. We add a graphite compound to enhance the already low coefficient of friction. This product offers outstanding mechanical strength, and wear resistance at temperatures up to 600°F.

 

FibreComp®

FibreComp uses the same resin system as WearComp, but incorporates milled carbon fiber and graphite for applications that require additional lubricity. FibreComp achieves the lowest frictional coefficient and the best mechanical properties. It is used for applications with high rotational speed and low impact intensity.
