Food-Grade LSR Used in YJCPOLYMER

What is Liquid Silicone Rubber (LSR)?

The odorless and odorless properties of Liquid Silicone Rubber (LSR) seamlessly combine with its inherent mold and antimicrobial properties to create a protective barrier that prevents the intrusion of unwanted contaminants. With LSR’s hydrophobic properties, resistance to moisture and ease of cleaning, it provides a protective barrier that protects the integrity of your food-related products.

YJCPOLYMER has decades of experience in mass production of food-grade liquid silicone rubber molded parts, serving global manufacturers. With our expertise, we can assist with all aspects of the production process, from the early design stages to part production and post-molding value-added processes.

Injection Molding: Our LSR injection molding produces high-precision parts with exceptional consistency and speed. The injection molding process can range from prototype to high-volume production. LSR molded parts have no burrs and minimal door breakage. We can help you optimize product quality, streamline time to market, and provide value-added solutions to ensure your budget fits.

What Products are Made Using Food-Grade LSR?

Food grade LSR is used to manufacture many different products, from those used in homes and commercial establishments to hospitals and schools. Food-grade silicone rubber can be used in applications that require FDA-approved materials or when extremely high resistance to chemical and bacterial contamination is required. Using LSR, some of the following products can be manufactured:

Baby bottles, pacifiers, tableware, beverage bottles and dispensers, and food storage products. These products must be both safe and powerful.

Cooking utensils, oven mitts, baking cups and molds, ice cube molds and a range of other products need to be able to withstand extremely high and very low temperatures. When using LSR, these products are more durable and last longer than traditional plastic products.

Valves, diaphragms, gaskets and seals exposed to food. This can range from home storage solutions to industrial equipment used to manufacture, process, transport and prepare food and beverages. LSR is an ideal choice, easy to sterilize, has low compression and compression set, even in heavy-duty applications.

These are just a few potential uses for food-grade liquid silicone rubber, and new products are constantly being developed and tested.

Several Features Make LSR Food Grade Solutions a Smart Choice for a Wide Range of Options:

Tasteless and tasteless: Food-grade LSR is tasteless and tasteless, ensuring that the purity and aroma of food and beverages remain unchanged. Rest assured knowing your product’s flavor integrity remains intact, delivering an unparalleled sensory experience.

Mechanically stable and chemically inert: Food-grade LSR exhibits stable mechanical properties over time, serving as a reliable material. Its chemical inertness protects against corrosive influences as well as certain chemical solutions (including alkalis and acids) and cleaning products.

Durability: Food-grade LSR effectively absorbs vibration, ensuring smooth and reliable operation in dynamic applications. Its inherent elasticity allows it to withstand repeated compression, easily returning to its original shape even under extreme temperature fluctuations.

Clean and safe: Food grade LSR is a clean and safe solution for producing, preparing and storing food products. Complying with strict regulations set by the U.S. Food and Drug Administration (FDA), its use seamlessly aligns with Hazard Analysis and Critical Control Point (HACCP) best practices. In addition, its hypoallergenicity and biocompatibility as well as its resistance to bacterial and mold growth ensure the highest hygiene and safety standards.

Design and processing flexibility: Due to its low viscosity, LSR provides designers with greater flexibility to accommodate parts with complex back faces, thin part geometries, micro parts and multi-material 2k assemblies.

Diverse applications: Food grade LSR can be used in single materials or multi-color applications. Two-color, multi-color or co-injection LSR injection molding processes integrate and combine food-grade LSR with other substrates in the same molding process, eliminating the need for secondary assembly operations.

Food-grade liquid silicone rubber injection molding offers many benefits, from fast cycle times to optimize productivity, cost-effective production at high volumes, to automation opportunities to maximize consistency, accuracy and enhanced safety.

Food-grade liquid silicone rubber is a leading material used in consumer products that produce, prepare and store food and beverages. Its process flexibility and numerous beneficial properties make it an ideal choice.
