High-cov yeeb nkab kev txhawb nqa yog foamed polymers nrog cov khoom ntawm cov yas, roj hmab, thiab cork, feem ntau yog muaj li ntawm isocyanates thiab polyethers, ntxiv rau foaming agents, catalysts, thiab hluav taws kub retardants, ua los ntawm high - ceev stirring thiab sib tov.
Cov npuas dej yog tsim los ntawm ntau txhiab tus me me, tsis sib xws, cov hlwb ywj pheej, ua rau peb -cov qauv honeycomb. It has high density, low thermal conductivity, low water absorption, and a superior texture compared to wood.
Nyob rau hauv Tuam Tshoj thiab Europe thiab America, nws yog siv rau cov yeeb nkab txhawb nqa, cov yeeb nkab sockets, thiab hangers nyob rau hauv petrochemical nroj tsuag, liquefied roj nroj tsuag, txias cia chaw, thiab central cua txias systems.
