hydraulic seals pu seal

Characters:PTMEG-MDI based PU (polyurethane) seal, good physical properties, good abrasion resistance, good hydrolysis resistance, good for after treating processing ability, low compression set, and good dynamic property. Our products are of stable quality.

Applications:Seals can be used for tractors and excavator.

Casting Polyurethane (CPU) is a kind of polyurethane elastomer which is produced by casting process, liquid components are cast into the mold and reacted to get the final part.

PU advantages:

Wide range of hardness (Shore 0A-85D)

Wear and abrasion resistance   


Pleasant feel / soft touch surface

Fastness to light for aliphatics (non - yellowing)

Elasticity / Flexibility

High resistance against oils and greases

Flexibility at low temperature

Low cost for processing
