PU Description:
PU, polyurethane is a kind of high molecular compound. PU materials display higher mechanical strength, high abrasion, wear and extrusion resistance, high pressure load capacity, as well as a high tear and elongation at break resistance. Also have good flexbility and very good ageing and ozone resistance.
Polyurethanes are divided into polyester and polyether types. They can be made into polyurethane plastics, polyurethane fibers, polyurethane rubber and elastomers.
Application:
PU materials are suitable for application in mineral oils and greases, hydraulic oils, silicone oils and greases, highly non-flammable hydraulis fluids HFA and HFB and water up to 50º C
PU Type:
PU rod
PU tube
PU billets
DEF SEALS offers PU Billets in either standard or custom sizes.
We also offer many kinds of other semi-products
