Bisphenol-free epoxy resins now available on a pilot scale
Furthermore, SPECIFIC POLYMERS’s objective is to bring its innovation through various production scales, gradually moving towards industrialization. For two of the previously mentioned references, i.e. DGEVA and PHTE, the first stage of industrial transfer has been achieved over the past three years.
We are now capable of ensuring pilot production of these bisphenol-free epoxy resins in quantities of several tens of kilograms.
We offer batches of 50g to 500g for sale. We can also fulfill bulk supply requests on demand.
DGEVA
DGEVA is a waxy, bisphenol-free epoxy resin that melts around 50°C to 60°C. It has a relatively low viscosity of 10-50 cP·s at temperatures between 60°C and 80°C. Its typical epoxy index ranges from 6.8 to 7.5 meq/g (EEW of approximately 135-150). When combined with suitable hardeners, it can achieve glass transition temperatures ranging from 50°C to 150°C.
PHTE
PHTE is a yellow to slightly orange, viscous liquid bisphenol-free epoxy resin. Its viscosity ranges from 25,000 to 100 cP·s over a temperature range of 30°C to 80°C. The typical epoxy index is between 7.2 and 8.5 meq/g (with an EEW of approximately 120-140). When formulated with suitable hardeners, it can achieve glass transition temperatures from 100°C to above 200°C.
