FDA Colored Silicone O Rings Encapsulated , Industrial O Rings High Flexibility
Silicone / VMQ: The silicones are a group of elastomeric materials made from silicone, oxygen, hydrogen and carbon. As a group, the silicones have poor tensile strength, tear resistance and abrasion resistance. Special compounds have beer made which have exceptional heat and compression set resistance. High strength compounds have also been developed but their strength does not compare to conventional rubber. Silicones possess excellent resistance to temperature extremes, Flexibility below - 175 degrees F (- 114 degrees C) has been demonstrated. The maximum temperature at which silicones are recommended for continuous service in dry air is 450 degrees F (232 degrees C). Silicone's retention of properties at these high temperatures is superior to other elastic materials, Silicone compounds are not normally recommended for dynamic sealing applications due to relatively low strength and high coefficient of friction. Many silicone compounds have a higher than normal mold shrinkage that results in finished parts being under mold shrinkage when produced in standard molds.
Trade Names:
ASTM D1418 Designation: MQ, PMQ, VMQ, PVMQ
ASTM D2000/SAE J200 Type, Class: FC, FE, GE
Apple Compound Designation: SL
Standard Color: Red,blue,yellow,black,white
Key Use(s): Static seals in extreme temperature situations. Seals for medical devices, compatible with FDA regulations.
Temperature Range:
Standard Compound: -40° to +220°C
Hardness (Shore A): 10 to 85
Features: Phenyl (PVMQ) based silicones can perform to -40°C. New polymers can take short term to 220°C.
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,acetone) or concentrated acids.
Test Method: With reference to US FDA 21 CFR 177.2600.
