Edra Equipamentos Develops Sustainable Technology for Composite Moulding

Table made using the RTM-G process

The Brazilian company Edra Equipamentos has developed a sustainable technology for the molding of composite parts. Named RTM-G or Resin Transfer Molding – 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 fibreglass or glass mat.

As well as 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 Equipamentos to produce furniture, in the initial testing phase tempered glass waste has rendered a very interesting aspect to the tables and benches that they produced.
