Though the viscosity of TPEs are reduced when processed at high shear rates, TPEs must be “packed” into a mold to ensure complete fill-out. Because LSR cures at high temperatures, using it as an overmold material in a two-component molding system requires pairing it with high temperature thermoplastics to overcome the risk of melting or deforming the substrate. You have the responsibility to conduct full-scale end-product performance testing to determine suitability in your application, and you assume all risk and liability arising from your use of the information and/or use or handling of any product.
