UTEC 3040说明:UTEC3040是一种超高分子量聚乙烯,分子量约为高密度聚乙烯(HDPE)树脂的10倍。这种极高的分子量使这种聚合物具有几种独特的性能,如高耐磨性、冲击强度和低摩擦系数,使其成为一种自润滑材料。应用:要求高抗冲击性的应用-技术和多孔零件、过滤器、压缩成型板。 UTEC 3040 UTEC3040 is an Ultra High Molecular Weight Polyethylene with a molecular weight about 10 times higher than High Density Polyethylene (HDPE) resins. This extremely high molecular weight yields several unique properties to this polymer such as high abrasion resistance and impact strength and low coefficient of friction, what makes it a self-lubricating material. Applications: Applications which require high impact resistance technical and porous parts, filters, compression molded sheets.
