What makes UHMW-PE such a distinctive and useful material? It’s the combination of excellent properties – outstanding abrasion resistance, superior impact resistance, non-sticking and self-lubricating properties and excellent mechanical properties, even in cryogenic conditions.
UHMW-PE is an extremely high viscosity polymer that is produced in the form of a powder and has an average particle size diameter typically ranging from 100-200 microns. As a result of its viscosity, it generally cannot be processed by the common methods used for ordinary thermoplastics. Thus, compression molding and ram extrusion processes are used to generate the high pressures needed to fuse UHMW-PE particles together and then, typically, are used to form the material into stock shapes or profiles with subsequent machining, as necessary.
Because of its abrasion resistance, chemical resistance and good frictional properties, major application areas of UHMW-PE include bulk material handling, food and beverage machinery; chemical, mining and mineral processing equipment, recreational equipment, transportation and orthopedic implants.
GUR UHMW-PE can also be gel processed for such applications as battery separators, synthetic paper or high-strength fiber applications. The free sintering process can be used to produce porous parts such as filters, wicking parts and fluid delivery components.
With its GUR® UHMW-PE, GHR® HMW-PE and VHMW-PE and its GUR® and Hostalloy® UHMW-PE products, Ticona is the largest global supplier with the broadest UHMW-PE portfolio in the industry. Included in this portfolio are GUR Specialty Products which are used to fabricate porous and filtration parts and as additives for paints, coatings or material matrix modifiers.
UHMW-PE为何如此独特?因为UHMW-PE综合了如下优异性能:高耐摩性,高抗冲性,表面不粘性以及自润滑性。并且, 即使低温条件下它亦能保持卓越的机械性能
UHMW-PE是一种具有极高粘度的聚合物,为粉末形状,其典型粒径范围为100-200微米。由于粘度很高,它通常不能用普通的热塑性塑料成型方法来加工,而是用模压或柱塞挤出工艺,在高压下把UHMW-PE粒子熔融并烧结为坯材或型材,必要的话,再进行后续机加工。
因为UHMW-PE的耐磨性、耐化学性和好的摩擦性,其主要应用领域包括大批量材料搬运、食品和饮料加工机械、化工、采矿及矿物加工设备、娱乐设施、运输,以及整形外科移植物。
GUR UHMW-PE也可在凝胶状下进行加工,其应用包括电池隔板,合成纸和高强度纤维等。它亦可以用自由烧结工艺来生产多孔制件,如过滤器、吸液部件和流动输送部件。
