Edra Develops Sustainable Technology for Composite Moulding

09 October 2012

Edra Equipamentos has developed a sustainable technology for the moulding of composite parts, named RTM-G (Resin Transfer Moulding – Glass) the process combines the injection of resin into the mould with the use of post-consumer waste from tempered glass, which acts as reinforcement material in place of traditional fiberglass or glass mat.

Besides allowing the reuse of the glass that would be discarded, the RTM-G only uses colourless resins derived from renewable and recycled sources. And the peroxide used for curing or hardening the polymers is free of phthalates, which are substances considered harmful to the environment. Initially, RTM-G will be used by Edra to produce furniture. “Tempered glass waste has rendered a very interesting aspect to the tables and benches that we have produced in the testing phase," said Jorge Braescher, CEO, Edra.
