Overview
Silopren™ LSR 2749 is a self-bonding injection molding silicone rubber material that offers adhesion to polycarbonate (PC), polybutylene terephthalate (PBT), and copolyesters without using a primer and without adhering to the mold. Adequate bond strength is reached immediately upon demolding. This self-bonding property of Silopren™ LSR 2749 makes it a cost-effective solution for multicomponent injection molding or insert molding.
