FDA silicone
LIXU
Lixu provides FDA silicone o rings in a variety sizes,materials and colors.
Definition:
FDA silicone O-rings are O-shaped sealing rings made of silicone rubber (VMQ) that meets FDA standards. They feature resistance to high and low temperatures, corrosion, and non-toxicity, and are suitable for use in food, medical, and other fields.
Material properties:
The FDA silicone O-ring is made of methyl vinyl silicone rubber (VMQ), which is an amorphous substance. Its special formula can withstand a temperature range of -100 to 300℃, and it also features resistance to ozone, ultraviolet rays and weak acid and alkali corrosion.
Type
Food-grade silicone O-rings can pass environmental protection SGS test reports such as UL, ROHS, RECH, 6P, FDA, NSF, etc. The product specifications include food-grade silicone O-rings, Japanese standard food-grade silicone O-rings, American standard food-grade silicone O-rings, gas-phase food-grade silicone O-rings, national standard food-grade silicone O-rings, high-temperature resistant food-grade silicone O-rings, ozone-resistant food-grade silicone O-rings, transparent food-grade silicone O-rings, etc.
Feature
High and low temperature resistance: The working temperature range is wide, generally reaching -100℃ to 300℃. With special formulas, it can even be extended to a wider temperature range.
Ozone oxidation resistance and ultraviolet resistance: It has good weather resistance and is not prone to aging.
Chemical stability: It does not react with any substance except strong alkali and hydrofluoric acid, and is insoluble in water and any solvent.
Non-toxic and odorless: Complies with international standards such as FDA, ensuring it is harmless to the human body, and is suitable for
the food and medical industries
Electrical insulation performance: It has excellent electrical insulation performance and its conductivity can be adjusted through additives.
Ii. Application Fields
Food industry: It is used for sealing food containers, baby bottles, straws, tubes, etc., to ensure food safety.
In the medical industry, it is highly favored as a sealing component for medical devices such as surgical instruments and infusion equipment due to its non-toxicity, odorlessness, and high environmental protection level.
In the industrial field: It is applicable to both dynamic sealing (axial reciprocating motion and low-speed rotation) and static sealing scenarios, such as industrial seals and automotive engines.
Iii. Specifications and Standards
<1> Specifications: The product specifications of the FDA silicone O-rings we can provide mainly include the American standard AS568, the international standard ISO3601, the Japanese standard JIS B2401, the British standard BS ISO3601 and other standard systems. At the same time, Custom size o rings can be carried out according to customer requirements.
Standard: Compliant with international standards such as FDA and Rohs to ensure the safety and environmental friendliness of the product. Attached is the FDA ROHS certificate
