Food Grade Silicone: Building Better Products for Food Processing and Consumer Goods

Food grade silicone has become one of the most trusted materials in modern manufacturing, and for good reason. It holds up to heat, resists degradation, and meets the strict compliance standards required for products that come into contact with food or consumers every day. At Moldtech, we manufacture custom rubber components using food grade silicone and other high-performance compounds for two industries that demand exceptional reliability: food processing and consumer goods.

Whether you’re looking for a rubber seal that can survive thousands of washdown cycles or a molded part that needs to feel right in a customer’s hand, material selection and precision molding make all the difference. Below, we’re breaking down why food grade silicone matters, where it shows up across food processing and consumer goods applications, and how Moldtech supports manufacturers in both spaces.

Why Food Grade Silicone Matters in Food Processing

Food processing facilities operate under some of the strictest sanitation and compliance requirements of any industry. Every rubber component that touches food, whether directly or indirectly, has to meet standards that keep products safe and consistent.

Food grade silicone is a go-to material in these environments because it can withstand high heat, repeated sterilization, and constant washdown without breaking down or shedding material into the product stream. Materials used in food-contact applications generally need to meet FDA requirements, most notably 21 CFR 177.2600, the federal regulation covering rubber articles intended for repeated use in contact with food. Compounds that meet this standard, along with other food grade rubber products like nitrile and EPDM, give manufacturers confidence that their equipment complies with federal requirements.

Common food processing applications for food grade silicone and other compliant rubber compounds include:

• Silicone gaskets and food grade rubber gaskets for equipment seals
• Sanitary seals for tanks, valves, and processing lines
• Rubber diaphragms for FDA-compliant valves and pump chambers used in sanitary fluid handling
• Silicone tubing and rubber tubing for food and beverage transfer lines
• Rubber rollers built to withstand washdown, temperature swings, and constant product contact

Sanitation requirements in food processing are non-negotiable. A rubber roller on a food processing conveyor, for example, needs to hold up through thousands of cycles in wet, chemical-heavy cleaning environments without cracking or degrading. That level of performance starts with the right material and is reinforced through precision molding.

Food Grade Silicone and Other Materials Built for Consumer Goods

Consumer goods manufacturing brings a different set of challenges. Instead of washdown resistance, the priority is often consistent part quality at scale, along with materials that feel and perform well in the hands of everyday users. Home appliances, personal care products, electronics and wearables, and lawn equipment all rely on custom molded rubber parts to function properly and stand up to daily use.

Food grade silicone often plays a role here too, particularly in kitchen appliances, food storage products, and personal care items where consumers expect the same safety standards they’d find in commercial food equipment. Beyond food grade silicone, consumer goods manufacturers also turn to compounds like nitrile, EPDM, and natural rubber depending on the application.

Common consumer goods components include:

• Custom rubber seals and custom rubber gaskets for appliance housings
• Rubber overmolding and overmolding on grips, buttons, and wearable devices
• Rubber bellows and boots for moving parts in appliances and lawn equipment
• Custom molded rubber parts designed to exact geometry and material specifications

One of the biggest advantages of working with a rubber molding company early in the design process is the ability to optimize part geometry and material selection together. That collaboration helps consumer goods manufacturers avoid premature product failure, inconsistent part quality, and the kind of supply chain delays that can stall a product launch.

Where Food Grade Silicone Fits Compared to Other Compounds

Food grade silicone isn’t the only material used across these industries, but it’s often the first choice when heat resistance, flexibility, and compliance all matter at once. Here’s how it generally compares to other common compounds:

For applications that call for FDA approved silicone or food contact grade LSR, Moldtech produces components using LSR and HCR silicone molding in cleanroom-controlled environments. This is the same process capability we rely on for medical grade silicone molding, which speaks to the level of precision and cleanliness these food-contact and consumer-facing parts require.

Products Moldtech Manufactures for Food Processing and Consumer Goods

As a full-service rubber molding company, Moldtech supports food processing and consumer goods manufacturers with an end-to-end process, from initial design through final assembly. Companies in both industries trust us for components such as:

• Seals and gaskets: Custom rubber seals and rubber gaskets engineered for leak-proof performance
• Diaphragms, boots, and bellows: Precision-molded for fluid control, actuation, and protection of moving parts
• Hoses and tubes: Silicone tubing, rubber tubing, and food grade rubber products for fluid and air transfer
• Rollers and wheels: Built to handle heavy loads, continuous use, and washdown conditions
• Custom molded parts: Designed to your exact specifications, whether that’s a food grade rubber gasket or a component for a new consumer product

We offer thermoset rubber injection molding, compression and transfer molding, sponge and foam molding, LSR and HCR silicone molding, overmolding and bonding, and micro molding, giving manufacturers the flexibility to choose the right process for their application.

Why Manufacturers Choose Moldtech

Moldtech is a vertically integrated manufacturer based in Lancaster, NY, operating out of nearly 50,000 square feet of production space. Our facility runs 24 hours a day, five days a week, so we can offer everything from quick-turn prototypes to high-volume production runs without sacrificing quality or lead time.

We’re ISO 9001:2015 compliant and certified to ISO 13485:2016 and IATF 16949:2016. We’re also AS9100 compliant and ITAR-registered, and our micro molding area operates as a Class 100,000 cleanroom. These certifications matter just as much for food processing and consumer goods manufacturers as they do for our aerospace and medical customers, because they reflect the same commitment to consistent, documented quality no matter the industry.

We’ve earned the trust of some of the biggest names in manufacturing, including Boeing, Bosch, Johnson & Johnson, and the U.S. military. That same level of precision and reliability is available to food processing and consumer goods companies looking for a long-term rubber molding partner.
