1.VMQ(Silicone)O-Ring Performance Specifications
Food grade silicone o-rings are primarily made from VMQ compounds that are non-toxic, odorless,and tasteless.These food grade o-ring solutions comply with FDA 21 CFR 177.2600 for rubber articles intended for repeated use in contact with food.FDA-compliantt silicone meets strict extraction limits for aqueous and fatty foods.The as 568213 o-rings offer excellent thermal stability with an operating temperature range from-60℃ to +200℃,and some compounds up to+230℃.Silicone possesses excellent resistance to extreme temperatures,ozone,UV light,weathering,and fungal growth.Food grade VMQ materials provide low compression set and are compatible with clean-in-place(CIP) chemicals,hot water,and steam used in food and beverage processing.
2.Food Packaging,Filling,and Sealing Machine Working Conditions
Machinery in the food industry,including food packaging machines,beverage filling machines,and automatic sealing machines,operates under strict hygiene requirements with frequent exposure to products,cleaning agents,and temperature cycles.In beverage filling machines,O-rings seal nozzle assemblies,piston fillers,valves,and pumps where direct contact with liquids occurs.VMQ silicone o-rings are selected to prevent chemical leaching or contamination while withstanding hot cleaning steam and rapid temperature changes.The AS-213 size is commonly used for mid-sized flange seals,pump housings, and fluid transfer connections.Low compression set in silicone ensures reliable sealing during thermal expansion and contraction,maintaining hygienic integrity in high-speed production lines.
