Custom moulded rubber for tough environments

Tough operational environments call for even tougher custom moulded rubber seals. Wherever extreme temperatures and abrasive chemicals are involved, specialised ‘O’ rings offer unrivalled performance and peace of mind. In this article, TRP Polymer Solutions discusses the merits of sourcing high temperature ‘O’ rings and chemical resistant ‘O’ rings from a source you can trust.

As far as we’re concerned, there is only one material capable of handling the most extreme operational conditions and that’s Perfluoroelastomer (FFKM). We’ve worked with this remarkable material for years. In fact, we rate it so highly that we even produced our own proprietary blends of FFKM, which we call TRPlast™, to meet the challenges of the most demanding industrial applications of today.

Why choose FFKM?

Put simply, FFKM offers unrivalled chemical and thermal resistance. We’re talking near universal chemical resistance and an operational temperature range of between -40 °C and +330 °C. This is the widest possible range for dynamic sealing in extreme temperatures. Not only that, but FFKM ‘O’ rings also offer the additional benefits of being resistant to gas and liquid permeation and oxygen-plasma. It truly is a remarkable material.

High temperature ‘O’ rings

Our high temperature ‘O’ rings are designed to operate in the extremely high temperatures that are prevalent across a variety of industries, from Chemical Processing and Transport to Oil and Gas recovery, Aerospace applications, and even Formula One race engines. Our TRPlast™ Perfluoroelastomer solutions can either be supplied as custom rubber mouldings or high temperature ‘O’ rings.

Chemical resistant ‘O’ rings

FFKM combines the advantageous mechanical properties of FKM with the chemical resistance of PTFE. It is this superior chemical resistance that sets FFKM ‘O’ rings apart. Thanks to its carbon-fluorine bonds, FFKM is resistant to no fewer than 1,800 different chemicals, including organic and inorganic acids, hydrocarbons and ketones – making chemical resistant ‘O’ rings ideal for the most heavy-duty of applications.

Buy FFKM seals from TRP Polymer Solutions

Our high-specification FFKM ‘O’ rings are available to most standard sizes (AS-568A, BS1806 , BS ISO 3601-1, BS ISO 3601-2) and are supported by a large range of non-standard tooling. Our extreme temperature ‘O’ rings can be supplied on lead times as short as 48-hours. Where tooling is required, custom mouldings may be supplied within 7 days, depending on the geometry of the part.

“For the toughest working environments, you can depend on FFKM ‘O’ rings and seals to deliver optimal levels of performance and safety,” said Peter Watts, CEO at TRP Polymer Solutions. “Our own unique blends of TRPlast™ perfluoroelastomers have been specially formulated to perform where most other seal materials would simply fail. We have total confidence in our custom moulded FFKM products, and so will you.”
