Eco-mineral specialist RockTron (Bristol / UK; www.rktron.com) and French compounder Eurostar Engineering Plastics (Fosses; www.eurostar-ep.com) have launched a grade of PP containing RockTron’s 100% recycled eco-mineral fillers. “Starpylen” ECR30K ECR contains 30% “MinTron” alumino-silicate solid glass spheres and has been designed to meet strict application requirements without compromising performance compared with traditional fillers.

The new grade is part of a range of thermoplastic compounds made with 100% recycled, low carbon reinforcing agents. RockTron says that they offer a cost effective solution, while meeting the demand for environmentally friendly and sustainable materials and are available in PP and PA. Eurostar is one of a number of compounders and polymer producers evaluating the company’s eco-mineral fillers in a range of thermoplastic and thermoset applications in Europe and the US.

The high performance fillers are produced using RockTron’s technology, which recycles fly ash waste from coal-fired power stations. It can process both fresh and stockpiled fly ash waste into fillers for commercial use, reducing the energy utilities’ impact on the environment. The range of eco-friendly mineral products that the process generates can be used as fillers in elastomers and coatings, as well as polymers.
