Polyurethane pwm kua nplaum
Cov txheej txheem kev ua tau zoo, tuaj yeem kho tau ntawm chav tsev kub, lub sijhawm luv luv demoulding, thiab xim tuaj yeem muab ntxiv los kho cov xim.Cov roj hmab tiav lawm muaj kev hnav zoo, dej tsis kam, pob tshab, zoo elasticity thiab ruaj khov loj.
Yuav hloov silicon roj hmab ntau lawm "kab lis kev cai pob zeb" pwm.Nws tseem tuaj yeem siv rau cov khoom siv hluav taws xob potting, roj hmab cov menyuam, roj hmab phaj, roj hmab log thiab khau pwm thiab lwm yam khoom.
