高压非石棉垫，非石棉法兰垫*

由于石棉纤维对人体有危害，而且在生产过程中对环境造成污染，随着经济发展，国家越来越注重环保，所以非石棉垫片/无石棉垫片是石棉垫片的代替品。                                                                                        

 非石棉垫片：是以芳纶纤维和有机纤维为主要材料制成的，以特种橡胶为粘结剂。含有一定量石棉（5%-10%）的垫片称为非石棉垫片，而*不含石棉的垫片称为无石棉垫片。                                                                      

 无石棉垫片是：以优质芳纶纤维、合成纤维和优质无机纤维，以特种橡胶为粘合剂制成的.      

 非石棉垫片适用介质：                                                                                                     

 用于水、蒸汽、空气、煤气、酸、碱溶液等。                                                                     

 非石棉垫片zui大加工尺寸：                                                                                               

  ~2000mm；特殊规格或各类非标准可按客户要求制定。                                                      

 非石棉垫片可分为：                                                                                                         

 低压非石棉垫片、中压非石棉垫片、高压非石棉垫片、耐油非石棉垫片
