Barberton, Ohio – GSDI, a subsidiary of PolyOne Corp. and a producer of dispersions for silicone rubber, has launched Silcosperse 500 dispersion, reports Rubber & Plastics News.
According to the company, the product increases the heat stability of high consistency silicone formulations to withstand temperatures up to 260°C, improving suitability for applications in the automotive, aerospace and appliances industries. Examples include seals, covers, insulators, gaskets and O-rings.
Tests show no compromise in processability and thermal performance, compared to traditional rare earth element-based technologies, the company said. The product is supplied as a millable dispersion gum to eliminate problems associated with messy, hard-to-handle alternatives. It is available in quantities as low as 4.5kg to allow for smaller volume, niche applications and inventory optimisation.
