What is a polyurethane damper and how does it differ from rubber?
A polyurethane damper is a cast elastomer component that absorbs impact and vibration. Compared to rubber, polyurethane offers much higher abrasion resistance, lower compression set, and better load-bearing capacity.
Can you produce a PU damper to match my drawing or sample?
Yes. We specialize in custom cast polyurethane dampers made to customer drawings or samples, including bonded inserts and threaded mounts.
How do I choose the right Shore hardness for my damper?
Hardness depends on impact energy, required stroke, and equipment mass. We provide application consultation and sample testing to determine the best Shore A value.
What is the typical lead time for custom dampers?
Prototyping can take 1–3 weeks depending on tooling; production lead times vary with quantity but commonly range from 2–6 weeks.
How do polyurethane dampers perform in outdoor or corrosive environments?
Standard polyurethane offers good weather resistance; additives improve UV, oil, or chemical resistance for harsh outdoor and corrosive conditions.
