As an important material in the food processing and packaging industry, food-grade silicone rubber sheet is widely used in a variety of food contact situations due to its safety and excellent performance. Understanding the requirements of food-grade silicone rubber sheets can help ensure food safety and product quality.

Safety Standards

Food-grade silicone rubber sheets must comply with stringent international and national safety standards, such as the U.S. Food and Drug Administration (FDA) standards, the German Federal Institute for Risk Assessment (BfR) standards, and the European Union's EU Food Contact Materials Regulation (EC 1935/2004). These standards define the composition, limits of migrating substances and hygiene requirements for food contact materials to ensure that no harmful substances are released when they come into contact with food.

Material purity

Food-grade silicone rubber sheets should be manufactured from high-purity silicone materials that are free from toxic and hazardous substances, such as heavy metals, plasticisers and organic volatiles. Its production process must strictly control the selection of raw materials and processing techniques to ensure the purity and safety of the final product.

Temperature Resistance

Food processing and storage environments often involve high and low temperature operations. As a result, food-grade silicone rubber sheets are required to have a wide range of temperature resistance, typically operating in temperatures from -60°C to +200°C. This excellent temperature resistance ensures that the final product is pure and free of contaminants. This excellent temperature resistance ensures that the physical and chemical properties are maintained in a variety of environments, including boiling, chilling and freezing.

Chemical resistance

Food-grade silicone rubber sheets also need to have excellent chemical resistance to acids, alkalis, greases and other chemicals commonly found in food processing. This characteristic ensures that it will not degrade or release harmful substances due to the action of chemical substances during long-term use, guaranteeing food safety and hygiene.

Odourless and non-toxic

Food grade silicone rubber sheet should not produce odour or affect the taste of food during use. In addition, it must be non-toxic to ensure that it is not hazardous to human health under any circumstances.

Application Examples

Food grade silicone rubber sheet is widely used in seals, gaskets and conveyor belts and other parts of food processing equipment. It plays an important role in areas such as baking, sugar production, dairy processing and beverage production. Its excellent temperature resistance, chemical resistance and safety ensure that food products always maintain high quality and safety during processing, storage and transport.

Summary

The high safety and excellent performance of food-grade silicone rubber sheets make them an important and indispensable material for the food processing industry. Strictly following the relevant standards and requirements and choosing high-quality food-grade silicone rubber sheets can help ensure food safety, improve product quality and meet consumers' health needs.
