Food Grade Silicone Sheet – Key Features
Our food grade silicone sheet strictly complies with FDA and LFGB standards, ensuring a completely non-toxic, BPA-free, and odorless profile that is safe for direct food contact. To eliminate compliance risks in your procurement process, every single batch comes with comprehensive certification reports and factory inspection certificates. This guarantees full-cycle production traceability, providing peace of mind for stringent food processing, commercial baking, and automated packaging facilities.
Engineered for extreme thermal stability, this material maintains its flexible, tactile resilience from **-40°C to 230°C** without any deformation, hardening, or cracking under continuous stress. Furthermore, the molecular structure is perfectly compatible with Clean-In-Place (CIP) and Sterilize-In-Place (SIP) protocols. It easily withstands high-temperature steam and standard chemical cleaning agents, meeting the rigorous sanitation demands of pharmaceutical and food-grade environments.
Featuring an exceptionally low compression set, this elastomer provides outstanding rebound force even after long-term, high-frequency mechanical pressure. The high elasticity and tear resistance translate to a highly reliable sealing effect, actively preventing fluid or gas leaks in critical equipment joints. It serves as the ideal foundation for heavy-duty gaskets, hygienic seals, and vibration-dampening cushion parts in complex machinery.
Beyond basic wear resistance, this material exhibits superior environmental resistance against moisture, ultraviolet (UV) exposure, and ozone aging. In complex, damp, or highly active processing environments, the sheet will not degrade, turn yellow, or emit any off-putting odors over time. This extended service life significantly outpaces standard rubber alternatives, directly reducing the frequency of maintenance shutdowns and replacement expenditures.
Available in a broad spectrum of thicknesses, widths, and hardness levels, we support advanced CNC die-cutting technology for rapid, mold-free prototyping of complex, custom-shaped gaskets based on your exact blueprints. To enhance visual hygiene management, we offer high-purity white and translucent standard options, allowing operators to instantly spot grease, residue, or surface contaminants. For specialized safety needs, we also provide metal-detectable formulations (such as highly visible blue) and antimicrobial options to prevent physical debris contamination and inhibit bacterial growth on the production line.
Selecting the correct sealing material requires a precise understanding of its physical and thermal capabilities. The data provided below outlines the exact specifications of our FDA-certified elastomer, demonstrating its structural integrity, tensile strength, and thermal endurance. These verified metrics ensure that the material will perform consistently under the mechanical stresses and temperature fluctuations typical of industrial food processing and pharmaceutical manufacturing. Please review the detailed parameters to confirm alignment with your specific equipment requirements.

Our food grade silicone sheet is extensively integrated into primary food processing lines as reliable sealing gaskets, vibration-dampening buffer pads, and hygienic lining materials. Fully compliant with FDA and LFGB standards, it provides a safe, non-toxic, and high-temperature resistant barrier for equipment handling raw meat, fresh fruit, vegetables, and liquid beverages. The smooth, non-porous surface finish actively prevents organic matter buildup, making daily washdowns faster and more effective.
Acting as a high-performance, high temp silicone sheet, this material is the optimal choice for sealing strips, vacuum cups, and compression gaskets within automated packaging machines. Its excellent elasticity and mechanical wear resistance guarantee a stable, airtight seal even on high-speed, continuous-motion production lines. This prevents vacuum leaks and packaging defects, thereby improving overall operational efficiency and safeguarding the final product's shelf life.
This food safe silicone sheet demonstrates exceptional thermal endurance in industrial ovens, heavy-duty dough mixers, and confectionery moulds. Operating flawlessly in ambient heat up to 230°C, it will not melt, warp, or release any chemical odors that could alter the taste of baked goods. Its inherently non-stick surface properties and easy-cleaning nature make it an indispensable component for commercial bakeries, large-scale kitchens, and catering equipment manufacturers.
Leveraging our advanced machining capabilities, the silicone sheet can be precision die-cut into a vast array of custom gaskets, O-rings, flanged seals, and bespoke components. It is widely applied across food machinery, dairy processing units, and hygiene industries where a long service life and absolute sealing reliability are non-negotiable. The material’s low compression set ensures that customized parts retain their exact dimensional tolerances over thousands of operational cycles.
Manufactured from ultra-pure, safe food grade silicone material, this sheet is perfectly suited for sensitive medical, cosmetic, and pharmaceutical machinery. It robustly supports repeated chemical sterilization, high-pressure steam, and aggressive cleaning regimens without degrading. By meeting the strictest hygiene requirements for high-standard production equipment, it helps facilities maintain a sterile environment and pass rigorous regulatory audits with ease.
Proper handling and installation of your sealing materials are essential to maximize their lifespan and maintain strict hygiene standards. Follow these operational guidelines to ensure optimal performance in your facility:
Surface Preparation: Before installing our food grade silicone sheet, meticulously clean and dry the mating surfaces on your machinery. Remove all traces of residual oil, dust, and previous gasket adhesives to ensure a flush, secure fit.
Precision Cutting: If you are not utilizing our pre-cut custom parts, carefully cut the sheet to your required dimensions for gaskets, seals, or lining applications using sharp, appropriate industrial cutting tools to prevent jagged edges.
Installation: Ensure even, tension-free placement on the food machinery or equipment. Apply uniform torque to bolts or clamps to take advantage of the material's low compression set, avoiding over-tightening which can cause distortion.
Operational Care: Keep the material away from sharp objects, abrasive tools, or direct open flames during daily operation. While the material is highly durable, physical punctures can compromise the sealing integrity.
Cleaning & Inspection: Utilize standard CIP/SIP processes for cleaning. The visual hygiene properties of the lighter-colored sheets will help you spot residue easily. Regular visual inspection and scheduled maintenance will significantly extend the service life of your high temp silicone sheet.
Food Grade Silicone Sheet
