Due to its inherent purity, inertness and biocompatibility, silicone is an extremely versatile material that lends itself to a broad range of application conditions and is a preferred choice of elastomer in the biomedical, pharmaceutical and healthcare industries. As a liquid raw material, silicone offers advantages in processing that render it a premier choice of material for technical components in high volumes.
Benefits of Silicone
Consistent mechanical properties from -45 °C to + 180 °C / -49 °F to +356 °F
Hardness from 10 to 80 Shore A
Platinum curing gives the highest purity material
Broad operating temperatures from -50 °C to +250 °C / -58 °F to +482 °F
Excellent heat resistance, dielectric strength and cold flexibility
Offers excellent resistance to ozone, weather and UV rays
Offers excellent electrical and mechanical damping properties
Sterilizable: γ-radiation, steam, EtO
No toxic combustion products
Biocompatibility – non-allergenic
Types of Silicone
There are principally two types of Silicone:
High Consistency Rubber (HCR), formulated with either peroxide cured systems or platinum cured systems
Liquid Silicone Rubber (LSR), formulated with platinum cured systems
Trelleborg Sealing Solutions offers a comprehensive portfolio of standard and proprietary grades within both categories. These cover a broad range of products and processes to suit specific market and application requirements.
Two Shot LSR Technology – the Ultimate LSR Process
One of our most outstanding capabilities is the simultaneous injection of LSR in combination with technical plastics, 2C LSR technology. In what is commonly referred to ask 2K, 2-shot, multi-component injection molding or co-injection, our LSR experts employ highly advanced and sophisticated tool and process engineering to develop the most innovation solutions, combining two, three or more individual materials into one fully bonded, robust component.
