Silopren™ LSR 4739
Silopren™ LSR 4739 is a 30A two-component self-bonding liquid silicone rubber that is recommended for use in healthcare and medical applications.
Silopren™ LSR 4739 is a two-component self-bonding silicone rubber material for injection molding applications. It offers primer-less adhesion to polycarbonate (PC), polybutylene terephthalate (PBT), and co-polyesters with a great bond strength that is reached immediately upon demolding.
This self-bonding property of LSR 2749 makes it a cost-effective solution for multi-component injection molding or insert molding.
Silopren™ LSR 4739 is specifically designed for use in medical applications since it is biocompatible and meets USP Class VI requirements.
Primerless adhesion to PC, PBT, and co-polyesters No special mold treatment required No adhesion to the mold Biocompatible Sterilizable with ethylene oxide, steam, and gamma radiation High-temperature stability Flexibility at lower temperatures Good dielectric and mechanical properties Easy to pigment
Problems Solved
Needing a primer for the adhesion of liquid silicon to polycarbonate (PC), polybutylene terephthalate (PBT), and co-polyesters substrates Resistance of liquid silicone rubbers to sterilization methods
Applications
Respiratory masks Sealing elements Membranes and diaphragms Connectors Surgical and dental handles and grips Dental handles and grips Other soft-hard combinations
