Dryflex WS range we have turned the usual water -resistant properties of tharmoplastic elastomers(TPE).on their head to create materials that swell up to ten times volume when immersed in water.these materials were developed to expand after contact with aqueous solutions to form a positive seak and prevent the ingress or exit of water.

Dryflex WS grades are typically available in a hardness range of between 25 and 40 shore A.

A hardness range enables the production of profiles, or moulded components, with varying degrees of flexibility. The benefits of a softer, more flexible profile may be seen both in terms of the manufacturing process and installation techniques.

Dryflex WS TPEs are primarily processed via extrusion processing techniques, but may also be injection moulded.

• In general these materials do not require pre-drying, however, after periods of prolonged storage pre-drying may be necessary.

• Venting of extrusion lines may be used as a method of preventing the build-up of volatiles during continuous processing.

• Cycle times for injection moulding will be governed by temperature and section thickness. Care must be taken to allow sufficient cooling of parts prior to demoulding in order to prevent permanent distortion of the article
