3M Dyneon聚四氟乙烯细粉TF 2071Z推荐用于管道、电线和电缆应用的制造。特殊特性符合ASTM D 4895 I型,1级,C类,高分子量聚四氟乙烯粉末,由乳液聚合生产,由于大的还原率(RR)范围较低的挤压压力,较之3M Dyneon聚四氟乙烯细粉tf 2053Z采用标准膏体挤压法加工,具有较宽的加工窗口,优异的化学性能。无聊 Low density moisture curable polyethylene compound for low voltage building wire applications (UL styles XHHW-2, RHW-2, RHH, SIS, USE-2). ed only when used. PEXIDAN® X/T is halogenated but is RoHS compliant. Also CSA listed for styles RW-90 and RWU-90 (-40°C rated) PEXIDAN® X/T is a low density flame-retardant XLPE system curable by moisture and consists of a silane pre-grafted base compound A-3001 and a flame retardant catalyst masterbatch CAT-005FR. Mixed and extruded in the proper proportions (80:20), the two components result in a material that is curable by exposure to 70-95°C hot water or even ambient moisture. In order to prevent pre-scorching the grafted compound and the catalyst masterbatch must be stored separately and mixed only when used. PEXIDAN®X/T is halogenated but is RoHS compliant. |
