牌号简介	说明Perlast® G75B提供了一种具有优异耐化学性、机械性能和高温稳定性的独特混合物，同时在所有三个方面扩展了操作限制。Perlast® G75B经过特殊配制，通过消除易受酸侵蚀的填料和优化聚合物结构来提高耐酸性。此外，这种全氟弹性体具有低渗透性，因此，它不容易膨胀，从而延长了阀门、泵和机械密封的使用性能。高模量使Perlast® G75B抗挤压，是中高压应用的理想选择。此外，低累积压缩永久变形在化学腐蚀性环境下提供了较高的平均维修周期间隔时间。Perlast® G75B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（任何尺寸的内径可达2米/6.5英尺）和定制形状。关键特性：对多种化学品具有优异的耐化学性、优异的耐酸性和耐胺性、优异的机械性能、高温下的长期密封效率、极低的放气性能、良好的耐蒸汽性（ASME BPE 2000），在200°C下336小时后，MIL-L-23699C喷射油的膨胀率小于2%，典型应用阳离子航空航天化学加工柴油半导体油气 Description Perlast® G75B offers a unique blend of excellent chemical resistance, mechanical properties and high temperature stability, simultaneously extending the operating limits in all three aspects. Perlast® G75B has been specially formulated to provide increased acid resistance by eliminating fillers that are prone to acid attack and optimising the polymer structure. In addition, this perfluoroelastomer has low permeability and as a result, it is less prone to swelling, leading to extended in-service performance in, for example, valves, pumps and mechanical seals. A high modulus makes Perlast® G75B resistant to extrusion and ideal for use in medium-high pressure applications. In addition, the low cumulative compression set provides a high mean-time between maintenance cycles in hot chemically aggressive environments. Perlast® G75B is suitable for both dynamic and static applications and can be fully moulded into O-rings (any size up to 2m/6.5ft internal diameter) and custom shapes. Key Attributes Excellent chemical resistance to a wide range of chemicals Exceptional acid and amine resistance Superior mechanical properties Long-term sealing efficiency at high temperature Extremely low out-gassing properties Good steam resistance (ASME BPE 2000) Less than 2% swell in MIL-L-23699C jet oil after 336 hours at 200°C Typical Applications Aerospace Chemical Processing Diesel Semiconductor Oil & Gas	Perlast® G75M是一种黑色、多用途、全氟弹性体化合物，对各种化学品具有终极的全方位抵抗力。Perlast® G75M提供了一个非常低的压缩永久变形，模量和硬度优化，以适应大多数密封应用。Perlast® G75M非常适合用于机械密封和多物质化工厂。Perlast® G75M可制成O形圈（直径达2米/6.5英尺的任何尺寸）和定制形状。关键特性极低的压缩永久变形优越的长期密封效率宽耐化学性高机械强度典型应用泵、阀门、机械密封、化学工艺和炼油工业联轴器和配件 Perlast® G75M is a black, multi-purpose, perfluoroelastomer compound that provides ultimate all-round resistance to a broad range of chemicals. Perlast® G75M offers an extremely low compression set, with modulus and hardness optimized to suit the majority of sealing applications. Perlast® G75M is ideally suited for use in mechanical seals and multi- substance chemical plants. Perlast® G75M can be moulded into O-rings (any size up to 2m/6.5ft diameter) and custom shapes. Key Attributes Extremely low compression set Superior long-term sealing efficiency Broad chemical resistance High mechanical strength Typical Applications Pumps Valves Mechanical seals Chemical process and refining industries Couplings & fittings
