Nws yog heev resistant rau kev kub siab, lub tshuab nqus tsev thiab compression. Nws muaj zog ncej siab thiab muaj kua heev. Lub vojvoog dabtsi yog khoov yog kwv yees li qhov sib npaug ntawm sab nraud. txoj kab uas hla, tuaj yeem tso tawm hluav taws xob zoo li qub kauv hlau grounding. Siv dav hauv cov khoom siv abrasive xws li hmoov av, hmoov, fibers, chips thiab hais, roj thiab kua ib puag ncig, rau kev tshem tawm plua plav thiab nqus cov nroj tsuag, tshuab nqus tsev ntxhua khaub ncaws, ntawv thiab textile fibers.

Thawj yog qhov tsw. Haus nws ua ntej koj pom nws. Cov ntxhiab tsw no yog tawm los ntawm polybrominated diphenyl ethers uas muaj nyob rau hauv inferior polyvinyl chloride siv los ua cov ntaub ntawv PVC. Polybrominated diphenyl ethers muaj teeb meem rau tib neeg thiab ib puag ncig ntuj. Nws raug mob hnyav zuj zus. Nws tsis hnov tsw tsis tu ncua thiab muaj roj-soluble, ua rau muaj kev phom sij rau tib neeg lub siab thiab lub paj hlwb.
