Sealing Technology
New sealing compound takes the pressure
P
recision Polymer Engineering (PPE) has launched a new multi-purpose perfluoroelastomer compound designed to offer both broad chemical resistance and low compression set. Perlast G75M is intended for application in extreme conditions, including high speed rotation, high temperature and high pressure. A compression set figure of 14% is quoted by the company. Potential applications include mechanical seals and multi-substance chemical plants, where it is suggested for pumps, valves, couplings and fittings with the potential for extended maintenance intervals. The modulus and hardness have been optimised to suit the majority of sealing applications and is available as O-rings up to two metre diameter and as custom shapes. Mick Holland, Global Products Manager at PPE comments: ‘The successful development of a multipurpose compound that excels in both chemical resistance and mechanical performance is groundbreaking news for anyone with high performance sealing requirements. We can’t wait to see how G75M transforms our customers’ applications.’

Turcon MF6 achieves NSF listing
T
urcon MF6 compound has been listed by NSF International as conforming to the requirements of NSF/ANSI Standard 51 – Food Equipment Materials. This material is part of a range of materials specifically engineered for demanding processing environments, including food and beverage production. Based on ultra-clean technology, these proprietary compounds are manufactured from high-purity PTFE grades and additives. They are designed to have a smooth finish, with high gloss and low porosity to avoid the risk of contamination build-up and reduce particle shedding. Each batch of material can be issued with a certificate of conformity and offers compliance to FDA 21 CFR177.1550, 3-A, USP Class VI and NSF/ANSI Standard 51. The materials are available as Variseal, a spring-energized sealing element or in other custom profiles. Contact: Trelleborg Sealing Solutions, Handwerkstrasse 5–7, D70565 Stuttgart, Germany.
