Sreath PES/TDI
cruas: cladach A 60A – cladach D 70D
Tha feartan comas-obrachaidh math aig an toradh, raon cruas farsaing, deagh chaitheamh caitheamh, fulangas agus feartan meacanaigeach sàr-mhath.
Air a chleachdadh airson toraidhean measgaichte elastomer polyurethane leithid cuibhlichean rubair, truinnsearan criathar, sgrìoban, fàinneachan ròin agus taidhrichean.
