Foam blocks yog siv dav hauv ntau yam lag luam, nrog rau kev ntim khoom, kev tsim kho, thiab kev ua si. Cov blocks no yog tsim los ntawm ntau yam ntaub ntawv, xws li ua npuas ncauj roj hmab, polyethylene ua npuas ncauj, thiab nthuav polystyrene (EPS) ua npuas ncauj, thiab lwm yam.
Ua npuas ncauj roj hmab, tseem hu ua cellular lossis daim txhuam cev roj hmab, yog tsim los ntawm cov khoom siv hluavtaws xws li neoprene thiab silicone. Nws yog cov khoom muag muag thiab hloov tau yooj yim uas tuaj yeem txiav tau yooj yim rau hauv ntau yam duab, ua rau nws zoo tagnrho rau kev siv cushioning. Foam roj hmab feem ntau yog siv rau hauv tsheb, marine, thiab rooj tog kev lag luam, thiab lwm yam.
Polyethylene ua npuas ncauj, tseem hu ua kaw-cell ua npuas ncauj, yog cov khoom siv nruj thiab ruaj khov uas muab cov rwb thaiv tsev zoo thiab cushioning. Nws yog tsim los ntawm extruding molten polyethylene los ntawm ib tug tuag, uas ua rau ib tug ua npuas ncauj nrog ib tug uniform cell qauv. Polyethylene ua npuas ncauj feem ntau yog siv rau hauv ntim, kev tsim kho, thiab cov khoom ua si.
Expanded polystyrene ua npuas ncauj (EPS) yog ib qho khoom siv hnyav thiab nruj ua los ntawm cov hlaws polystyrene uas nthuav dav los ntawm tshav kub thiab chav. Nws muaj cov khoom siv insulating zoo heev thiab feem ntau siv rau hauv ntim, kev tsim kho, thiab kev siv rwb thaiv tsev. EPS ua npuas ncauj kuj tseem siv rau hauv kev tsim cov surfboards, ua npuas ncauj thaiv rau cov pas dej da dej thiab lwm yam kev siv ua si.
Txawm hais tias cov khoom siv los tsim ua npuas ncauj blocks, lawv yog cov khoom tseem ceeb hauv ntau yam khoom thiab kev siv. Foam blocks muab kev tiv thaiv, rwb thaiv tsev, thiab cushioning nyob rau hauv ntau yam kev lag luam thiab kev siv. Yog li ntawd, lawv ua kom cov tuam txhab tsim cov khoom lag luam zoo tshaj plaws uas ua haujlwm zoo thiab nyab xeeb.
