COMBINING LIQUID-SILICONE-RUBBERS WITH THERMOPLASTICS TO RIGID-FLEXIBLE COMBINATIONS USING 2-COMPONENT INJECTION MOLDING

摘要

Since multi component injection molding techniques are well established, the development of rigid-flexible combinations is increasing. Besides combinations between thermoplastics and thermoplastic elastomers (TPE) which are used in various applications, the combination of Liquid-Silicone-Rubbers (LSR) and thermoplastics becomes more important because of their better thermomechanical and mechanical properties in comparison with TPE. Concerning the adhesive strength of these combinations which depends on the properties of the materials, the process parameters in the molding process and the mold-technique there is only insufficient knowledge. To solve this techniques are developed to improve the adhesive strength between the materials.
