• I-PU Foam yokuzikhupha ngokwakho:I-foam ye-polyurethane ye-self-skinning yimpahla ye-foam eyenza i-self-sealing layer phezu komhlaba ngexesha lokukhupha amagwebu.Inobuso obugudileyo kunye nobunzima obuphezulu, obusetyenziswa ngokuqhelekileyo kwiimveliso ezifuna ukugudiswa kwendawo kunye nokumelana nokunxiba.I-foam ye-PU ye-self-skinning isetyenziswa ngokubanzi kwifenitshala, izihlalo zeemoto, izixhobo zokufaneleka, kunye nezinye iindawo, ukubonelela ngeemveliso ngenkangeleko enhle kunye nokuqina.

(2) Polyurethane Elastomer (PU Elastomer)
I-polyurethane elastomer ine-elastomer egqwesileyo kunye nokumelana nokunxiba, okuqhelekileyo kusetyenziswa ekwenzeni amatayara, izitywina, izixhobo zokudambisa i-vibration, njl. Ngokuxhomekeke kwiimfuno, i-polyurethane elastomers inokuqulunqwa ukuba ibe yimveliso enobunzima obahlukeneyo kunye noluhlu lokunwebeka ukuhlangabezana neemfuno zamashishini ahlukeneyo. kunye neemveliso zabathengi.

(3)I-Polyurethane Adhesive (PU Adhesive)

Polyurethane adhesiveineepropati ezibalaseleyo zokudibanisa kunye nokuchasana kokusingqongileyo, isetyenziswe ngokubanzi kwi-woodworking, ukuveliswa kweemoto, i-textile adhesive, njl.
