PU Description:
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.
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.
