Gammadot Rheology signs agreement with RAPRA Ltd


Gammadot Rheology is pleased to announce that it has agreed to work with RAPRA Limited as a preferred provider.

RAPRA Limited is the leading not for profit research organisation for companies in manufacturing, processing or end use who are involved in polymers. Founded in 1919 RAPRA offers impartial and independent support to members and non-members involved in all kinds of polymer related R&D from a range of world class preferred service providers. Steve Shaw, RAPRA Executive Director says "we are extremely pleased to be working with Gammadot Rheology, experts in this area where scientific testing and measurement of 'real' materials are merged with highly specialised software modelling tools." He added "These both enable the designer to reliably predict the behaviour of a material during processing to maximise quality and performance of a product as a result of optimal manufacturing."

Gammadot Rheology is an independent testing laboratory that offers a range of testing services based on over two decades of providing rheology and materials characterisation support to the plastics and rubber industries. Mark Edwards, Gammadot's Principal, said of the agreement "Gammadot is looking forward to working alongside RAPRA and providing the membership and other clients with fast, accurate solutions to all their Rheology and material characterisation needs”
