Wacker releases ELASTOSIL LR 5471, a platinum-cured liquid silicone rubber tailored for food contact and medical composite parts. Unlike traditional LSR grades, this formulation reaches low volatile levels right after molding, skipping time-consuming post-bake treatment. It sticks reliably to common engineering plastics and metals without extra primers, cutting production cycle time for molders. The material meets BfR food safety standards, suitable for baby care items, kitchen seals and wearable sensor housings. Manufacturers can reduce oven energy use and lower defect rates during high-volume injection runs. It fills market demand for simplified composite molding solutions for global food and medical silicone suppliers.
