Food Grade Silicone

Food Grade Silicone

Food grade silicone products — sealants, lubricants, and release agents — are formulated for use in environments where contact with food, beverages, or pharmaceutical products may occur. Standard silicones may contain additives and plasticisers that are not approved for food contact; food grade silicones use formulations compliant with regulatory standards that permit incidental food contact. AIMS Industrial supplies food grade silicone sealants and lubricants for food processing, beverage, and clean facility applications across Australia.

NSF H1 and H2 Ratings

The NSF (National Sanitation Foundation) rating system is the most widely referenced standard for food contact lubricants and sealants in Australian food and beverage manufacturing. NSF H1 (food grade lubricants and sealants) are approved for incidental contact with food — they can be used in areas where occasional, unintended contact with food products may occur. NSF H2 rated products are not for food contact areas but meet food processing facility standards for non-food zones. AIMS stocks NSF H1 rated silicone products for compliant food processing applications.

Food Grade Silicone Sealant

Food grade silicone sealant seals joints, gaps, and penetrations in food processing and beverage equipment — between stainless steel panels, around pipe penetrations, and at equipment interfaces where water ingress or contamination must be prevented. Unlike standard silicone sealants, food grade formulations do not contain fungicides or other additives that would be unacceptable in a food environment. White or translucent colour is standard for food grade sealants, allowing visual inspection for cleanliness.

Food Grade Silicone Lubricant

Food grade silicone lubricant (silicone oil or silicone grease) reduces friction on conveyor components, guide rails, mould release surfaces, and mechanical interfaces in food and beverage equipment. Silicone-based lubricants are inherently inert, non-toxic, and resistant to the temperature extremes and cleaning chemical exposure of food processing environments. They do not support microbial growth and are not absorbed by food products on incidental contact.

Audit and Compliance Documentation

Food and beverage manufacturers operating under HACCP or SQF food safety management systems are required to document all chemicals used on the production floor, including lubricants and sealants. NSF registration numbers allow traceability in compliance documentation. For food grade silicone product selection and compliance documentation support, contact our team.

Storage and Shelf Life

Food grade silicone sealants and lubricants should be stored in dry conditions within the manufacturer's recommended temperature range. Silicone sealants have a shelf life typically of 12–18 months from manufacture date; product used beyond its shelf life may not cure correctly or may exhibit reduced adhesion. AIMS Industrial supplies food grade silicone products for food and beverage processing, pharmaceutical, and clean facility applications, and maintains stock for regular supply to Australian food manufacturers.
