Silopren™ LSR 2749 is a 40A two-component, self-bonding liquid silicone rubber with a 40 Shore A hardness.
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.
Shore A hardness: 40
Tensile strength, MPa: 7
Elongation at break, %: 600
Tear strength, die B, kN/m: 40
Primary Chemistry: Liquid silicone rubber
Primer required for adhering liquid silicone to polycarbonate (PC), polybutylene terephthalate (PBT), and copolyester substrates Increased cost with the use of liquid silicones in injection molding and insert molding applications
