2. Liquid Silicone Rubber Processing Capabilities
About Silicone:
Matched to the needs of life sciences, silicone is a premier
elastomer material with unique and advanced attributes.
For medical applications, its matchless inertness and
biocompatibility makes it the most suitable elastomer
when considering potential bacteria growth and alleviating
contamination. It is also the most widely tested and proven
material related to human compatibility. In addition, silicone‘s
mechanical properties prove to be excellent in dynamic
applications where accuracy, consistency and longevity are
important performance determining factors.
Markets Served:
• Life sciences
• Baby care
• Food & beverage
• Sanitary industry
• Appliances
LSR Injection Molding is ideal for:
• High precision requirements
• Complicated geometrical features
• Thin wall thicknesses (as low as 0.10mm / .004 inch)
• Extremely high volumes
• Fully automated production to ensure maximum process
control and consistency of product
• Parts tolerating little to no flash
• Miniature components
Silicone (VMQ) - General Characteristics:
• Food-safe, clean and transparent
• Hardness of Shore A 10 to 80
• Good thermal stability
• Excellent resistance to weather, ozone and UV rays
• Excellent electric insulation properties
• Biocompatibility: USP Class VI, ISO 10993
• Withstand sterilization by: γ-radiation, steam, ethylene oxide (EtO)
• Neutral in taste and smell
