由于石棉纖維對(duì)人體有危害，而且在生產(chǎn)過(guò)程中對(duì)環(huán)境造成污染，隨著經(jīng)濟(jì)發(fā)展，國(guó)家越來(lái)越注重環(huán)保，所以非石棉墊片/無(wú)石棉墊片是石棉墊片的代替品。                                                                                        

 非石棉墊片：是以芳綸纖維和有機(jī)纖維為主要材料制成的，以特種橡膠為粘結(jié)劑。含有一定量石棉（5%-10%）的墊片稱(chēng)為非石棉墊片，而*不含石棉的墊片稱(chēng)為無(wú)石棉墊片。                                                                      

 無(wú)石棉墊片是：以?xún)?yōu)質(zhì)芳綸纖維、合成纖維和優(yōu)質(zhì)無(wú)機(jī)纖維，以特種橡膠為粘合劑制成的.      

 非石棉墊片適用介質(zhì)：                                                                                                     

 用于水、蒸汽、空氣、煤氣、酸、堿溶液等。                                                                     

 非石棉墊片zui大加工尺寸：                                                                                               

  ~2000mm；特殊規(guī)格或各類(lèi)非標(biāo)準(zhǔn)可按客戶(hù)要求制定。                                                      

 非石棉墊片可分為：                                                                                                         

 低壓非石棉墊片、中壓非石棉墊片、高壓非石棉墊片、耐油非石棉墊片
