產(chǎn)品用途:
芳綸橡膠墊片是由芳綸纖維為主要代石棉纖維、全硫化的丁晴橡膠、特殊耐熱纖維、玻璃纖維、無機質(zhì)加強材料等有機無機填料壓縮組合而成,具有良好的耐熱性能;熱傳導(dǎo)率低,優(yōu)異的耐油、耐水密封性能和突出的氣密性,較高的機械強度,壓縮回彈率好,具有廣泛的介質(zhì)適應(yīng)性,滿足大多數(shù)苛刻工況的密封要求,是高性價比的密封材料。且有石棉纖維橡膠所不能替代的優(yōu)點,是石棉耐油橡膠板的良好替代品,也是綠色環(huán)保型的密封材料。
非石棉墊片是根據(jù)各種具體工況要求,以非石棉密封材料(非石棉抄取板,非石棉壓縮板,非石棉橡膠板等不含石棉的材料),用模具或各種工具沖壓,剪切而成的各種形狀的密封產(chǎn)品.
目前已在船舶、石化、航空、汽車等行業(yè)應(yīng)用數(shù)十年之久,是潤滑油、燃油、蒸汽、海水、壓縮空氣、中等酸堿理想的密封材料。
