Entropy Resins Widens its Scope in Composites Markets with Bioepoxy

Entropy Resins is bringing its Super Sap bio-based epoxy to market to give companies more options when it comes to high quality green materials to use in composite products.

In the US, the market for epoxy stands at $5 billion and $15 billion globally. As the sole producer of bioderived epoxy and with growing concerns for the environmental impact of products, Entropy looks well set for growth.

Lead Applications Engineer for Entropy, states Desi Banatao:
"With new industry standards and government legislation focused on reducing greenhouse gas emissions and maximizing the sustainability of our natural resources, we feel there are further opportunities for our bio-based technology."

Entropy’s technology allows them to produce the starting chemicals for epoxy manufacture from bio-based feedstocks, resulting in a product which is sustainable and has lower CO2 emissions than from petroleum feedstocks.

Entropy's lead biochemist, Rey Banatao:
"By sharing bio-renewable feed stocks with other industries, like the paper pulp and bio-fuels industries, and using manufacturing processes that require less energy and water we can significantly reduce the carbon footprint of our resins. Considering resins can be more than 50% of the volume in a composite structure, these savings can be environmentally significant."

Some of Entropy’s biggest buyers have been manufacturers of sports equipment; in 2010 the company formed partnerships with a number of surfboard, skateboard and ski manufacturers. Niche Snowboards is one such company. Niche now use SuperSap in their whole line of snowboards. Dustin Morrell, the CEO of Niche, said that while they had been eager to improve how environmentally friendly their product is, before Entropy’s bio-epoxy they hadn’t encountered a green product that could stand up to the level of physical stress needed to make the grade in one of their snowboards.

This year, however, Entropy is branching out into the wider composites market and meeting demands for high performance biodegradable products. They are expanding into supplying their bio-epoxy to the wind power, transport and civil engineering sectors. Typically these sectors use non-renewable or energy intense resources such as metal or a plethora of high performance plastics.Often the reason manufacturers stick to these materials is the same reason as why Niche didn’t use green composites earlier; strict demands for high performance. To aid this expansion, Entropy will be launching a line of coatings and adhesives aimed at the construction industry and also resin infusion systems that will make it easier to make large composite parts (such as wind turbine blades) with their technology.
