This self-adhesive Liquid Silicone Rubber (LSR) is a two-component, semi-transparent silicone designed for strong adhesion to PA substrates. It bonds effectively to glass surfaces while easily releasing from metal molds. The LSR is simple to dye and offers excellent mold release properties, making it ideal for applications requiring secure bonding to PA materials.
Product Features of Self-Adhesive Liquid Silicone Rubber for PA
- Rapid curing
- Superior mechanical properties
- Compatible with both injection molding and compression molding processes
Application Fields of Self-Adhesive Liquid Silicone Rubber for PA
Particularly suitable for one-step molding applications that combine PA and silicone, such as in earphones and other electronic devices.
