Perlast® ICE G75LT具有优异的耐化学性和低温性能。这种全氟弹性体材料是专门开发的,可在极端条件下,在-46°C(-51°F)的低温下使用。Perlast® ICE G75LT的配方是为了通过仔细控制分子结构来增加对多种化学品的抵抗力。此外,这种全氟弹性体具有低渗透性,因此,它不容易膨胀,导致阀门、泵和机械密封的使用性能延长。非常适合用于勘探和完井应用以及在零下条件下运行或储存的设备。Perlast® ICE G75LT既适用于动态应用,也适用于静态应用,可完全成型为O型环(内径不超过2.5 m/8 ft的任何尺寸)和定制形状。关键特性优良的低温密封性能良好的耐高温性低压缩永久变形优良的耐化学性广泛的化学品优异的耐酸性和耐胺性良好的机械性能典型应用航空航天.静态O型环化学处理.泵和阀的机械密封下降趋势M炼油厂和石油化工设备低温设备气体储存和运输石油天然气-海底设备完成工具钻井工具(深水)管道接头泵、阀门和压缩机 Perlast® ICE G75LT offers a unique combination of excellent chemical resistance and low temperature performance. This perflouroelastomer material has been specifically developed to perform under extreme conditions, in temperatures as low as -46°C (-51°F). Perlast® ICE G75LT has been formulated to provide increased resistance to a broad range of chemicals by carefully controlling the molecular architecture. In addition, this perfluoroelastomer has low permeability and as a result, it is less prone to swelling, leading to extended in-service performance in valves, pumps and mechanical seals. Ideal for use in exploration and completion applications and equipment operating or stored in sub-zero conditions. Perlast® ICE G75LT is suitable for both dynamic and static applications and can be fully moulded into O-rings (any size up to 2.5m/8ft internal diameter) and custom shapes. Key Attributes Excellent low-temperature sealing capability Good high temperature resistance Low compression set Excellent chemical resistance to a broad range of chemicals Exceptional acid and amine resistance Good mechanical properties Typical Applications Aerospace - static O-rings Chemical processing - pumps & valves Mechanical seals Downstream refinery & petrochem equipment Cryogenic equipment Gas storage & transportation Oil & Gas - subsea equipment Completion tools Drilling tools (deepwater) Pipe connectors Pumps, valves & compressors |
