Food Grade Silicone Rubber

Stockwell Elastomerics offers silicone rubber that meets FDA 21 CFR 177.2600 suitable for indirect food contact, including injection molded liquid silicone rubber for custom 3D parts. For special applications requiring better tear strength or elongation, Stockwell Elastomerics compression molds SSP4749-XX platinum cured high consistency rubber (HCR).

FDA 21 CFR 177.2600 Rubber

Part 177 indicates indirect food additives, specifically polymers. Section 177.2600 is specifically for rubber articles intended for repeated use; this is referring to rubber materials used in producing, manufacturing, packing, food producta. FDA 21 CFR 177.2600 is a reference of materials that are generally recognized as safe. Stockwell Elastomerics manufactures custom rubber components from FDA compounds such as SSP4749-XX HCR and SE20XX liquid silicone rubber (LSR).

FDA Liquid Silicone Rubber (LSR) for Food Contact

Stockwell Elastomerics offers molded liquid silicone rubber that is injection molded for shorter cycle times. Liquid injection molding is an automated process where Part A and Part B liquids are mixed and shot into a steel mold to cure. Stockwell Elastomerics’ food grade LSRs are available in durometers from 10 through 70 on the Shore A scale; translucent (unpigmented) is standard color.

• SE2010 – 10 durometer liquid silicone rubber (LSR)
• SE2020 – 20 durometer liquid silicone rubber (LSR)
• SE2030 – 30 durometer liquid silicone rubber (LSR)
• SSP4749-30LV – 30 durometer High Consistency Rubber (HCR) with Post-Cure
• SE2040 – 40 durometer liquid silicone rubber (LSR)

FDA High Consistency Rubber (HCR) – SSP4749-XX

Stockwell Elastomerics offers SSP4749-XX silicone rubber sheets that meet the FDA 21 CFR 177.2600 regulation for indirect food contact. This HCR silicone rubber is used for die cut, water jet, and tool-less flash cut parts used in food processing environments. SSP4749-XX is an FDA, unpigmented, platinum catalyzed gum based silicone rubber with excellent physical properties. Stockwell Elastomerics also offers SSP4749-XX FDA silicone rubber in compression molded 3D parts for special applications.
