Questions about bumpers and gaskets
-
What is the advantage of PU bumpers over rubber?
Polyurethane bumpers have higher load-bearing capacity, better rebound, and last significantly longer than rubber in repeated impact applications. They also maintain their shape over time. -
Can you bond bumpers directly to metal?
Yes. We bond polyurethane to steel, aluminum, and stainless steel. The chemical bond is integral to the part, not adhesive-based. -
Do you produce custom gasket shapes?
Yes. We mold gaskets to your exact profile. Send us a drawing or sample and we will produce the tooling and parts.
