70 Shore Clear Silicone O Ring Seals

1.Names: Silicone, VMQ

Both o-rings and gaskets can be made from silicone materials.

2.COMPATIBILITY

Chemical Resistance

Engine and transmission oil (e.g. ASTM oil No.1)
Animal and vegetable oil and grease
Brake fluid (non-petroleum base)
Fire-resistant hydraulic fluid, HFD-R and HFD-S
High molecular weight chlorinated aromatic hydrocarbons (including flame-resistant insulators, and coolant for transformers)
Moderate water resistance
Diluted salt solutions
Ozone, aging, and weather resistant

3.Description: A group of elastomers, made from silicon, oxygen, and hydrogen, Silicones are renowned for their retention of flexibility and low compression set characteristics, within one of the widest working temperature ranges for elastomers.

4.Key Use(s): Static seals in extreme temperature situations. Seals for medical devices, compatible with FDA regulations.

Temperature Range:
Standard Compound: -85° to +400°F

Hardness (Shore A): 40 to 85

Features: Phenyl (PVMQ) based silicones can perform to -85°F. New polymers can take short term to 600°F.

Limitations: Generally, low abrasion and tear resistance, and high friction characteristics preclude silicones from effectively sealing some dynamic applications. Silicones are also highly permeable to gases and are generally not recommended for exposure to ketones (MEK,) or concentrated acids.
