Description: When properly prepared, possible benefits include fulfillment of class VI or ISO 10993 requirements, withstand sterilization with gamma, etO and Steam. Medical grade colorants can be used to color parts for visual examination or marketing affects. Resistant to most cleaning agents. inert material which does not promote microbial growth.
Key Use(s): High volume syringe application. Face mask or inhalers without concerns of skin reactions.
Temperature Range:
Standard Compound: -85° to +400°F
Special Compound: -148° to +400°F
Hardness (Shore A): 10 to 80
Features: Medical grade silicone oil impregnated, allows for self lubrication material. Implant grade available upon request.
Limitations: Generally, low abrasion and tear resistance, and high friction characteristics preclude silicones from effectively sealing some dynamic applications. Silicones are also high highly permeable to gases and are generally not recommended for exposure to ketones (MEK,acetone) or concentrated acids.
