The market for high-quality, durable bakeware and consumer goods is booming, and food-grade silicone has become a top choice due to its strength and resistance to stress. This versatile material is perfect for manufacturing baking trays, bottle dispensers, and other kitchen products, as well as industrial-grade gaskets and seals used in commercial cooking appliances.
At kitchenbathsilicone, we specialize in large-scale production of food-grade liquid silicone molded components for major manufacturers, including Fortune 100 and Fortune 500 companies. Our expertise covers all aspects of the manufacturing process, from mold development to packaging.In this blog,we will introduce some knowledge about the Liquid Silicone Rubber for you.
What is Liquid Silicone Rubber (LSR)?
Liquid Silicone Rubber (LSR) is a popular elastomer, prized for its excellent heat resistance, flexibility, and non-stick properties. It’s odorless, tasteless, and highly resistant to mold and bacteria, making it an ideal material for products that come in contact with food. Additionally, LSR is hydrophobic, ensuring optimal performance even in harsh environments.
At kitchenbathsilicone, we work with a variety of food-grade elastomers from leading manufacturers. After thoroughly evaluating your budget and project requirements, we’ll recommend the most suitable raw materials to meet your needs.
Injection Molding Solutions
In addition to offering various LSR grades with distinct properties, kitchenbathsilicone provides flexible design options tailored to any project. Our services include:
– Injection Molding: LSR injection molding delivers high-precision parts with exceptional speed and consistency. This scalable process, from prototype to full production, yields parts that are flash-free with minimal gate marks. We also offer mold development, maintenance, and optimization to help you reduce lead times and keep your project within budget.
– 2-Shot Injection Molding: For more intricate parts, 2-shot injection molding offers added design flexibility by overmolding LSR onto plastic substrates. This technique is ideal for creating strong, integrated components like silicone grips for kitchen utensils, while eliminating the need for additional assembly steps, saving time and reducing costs.
By leveraging our expertise in LSR molding, kitchenbathsilicone helps streamline your product’s journey from concept to market. We also provide in-line assembly, design consulting, packaging, and shipping services to ensure your project’s success.

Benefits of Food-Grade Silicone Rubber
At kitchenbathsilicone, we produce a wide range of food-grade LSR products tailored to specific food and beverage applications. When compared to traditional rubbers or plastics, LSR offers several unique advantages:
– Durability: Food-grade LSR components are flame-retardant, corrosion-resistant, and built to endure the daily wear and tear of kitchen or industrial environments. These parts are also exceptionally pure, absorb vibrations effectively, and exhibit low compression set, ensuring long-term reliability.
– Manufacturing Flexibility: LSR parts can be produced using both conventional and 2-shot injection molding methods, offering increased design flexibility and a broad range of applications. Contact kitchenbathsilicone to learn more about our technical capabilities.
– Temperature Resistance: LSR retains its properties in extreme temperatures, from high heat to freezing conditions. It won’t melt or become brittle, making it a reliable material for kitchenware and industrial equipment exposed to varying temperatures.
– Bacterial and Chemical Resistance: LSR is chemically inert and resistant to bacterial growth and mold, offering a hygienic solution for food-related applications. This aligns with HACCP guidelines, providing added peace of mind in risk management.
– FDA Compliance: LSR is an ideal material for meeting FDA regulations for food and beverage products, ensuring your products are safe and legally compliant.
Due to its versatility and high resistance to environmental factors, food-grade LSR is an excellent choice for applications ranging from household kitchens to large-scale industrial operations. FDA-approved food-grade LSR is also available for use in areas requiring strict contamination controls.
Potential Applications of Food-Grade LSR
Some common products made from food-grade LSR include:
– Baking molds, ice cube trays, and kitchenware: LSR molds and trays offer durability and resistance to both freezing and high-temperature cooking. They last longer than traditional plastic alternatives and don’t become brittle under extreme conditions.
– Kitchen utensils and grips: LSR is ideal for spatulas, knives, whisks, and other utensils due to its inert nature and resistance to bacteria. It can be easily overmolded onto plastic components, creating complex parts with lower labor and overhead costs.
– O-rings, gaskets, and seals for food-related equipment: LSR’s durability and ease of sterilization make it ideal for seals used in food storage, processing, and transport applications. Its low compression set ensures consistent performance, even under heavy-duty conditions.
These are just a few examples of how food-grade LSR is used. New products and applications are being explored and developed continuously.
Food-Grade LSR in Practice
At kitchenbathsilicone, we have extensive experience utilizing food-grade LSR for mold-making and other production needs. One of our key specialties is helping clients navigate complex challenges in the food and beverage sector. For instance, when BPA-containing plastics were phased out, many manufacturers struggled to find a suitable alternative. One of our clients encountered structural issues with PBT (polybutylene terephthalate), their proposed substitute. We solved this problem by developing an LSR seal that bonded seamlessly with the PBT, using a 2-shot injection molding process to eliminate additional labor costs and ensure tight tolerances.

Developing Food-Grade LSR Molds
Designing food-grade LSR parts begins with precision mold development. This process requires specialized equipment and careful consideration of several factors, such as:
– Functionality: How will the part be used, and will it interact with other components?
– Environmental Factors: What conditions will the part be exposed to, and what material properties are necessary?
– Aesthetics: What are the cosmetic requirements? Will the part be used in consumer-facing applications?
– Regulatory Compliance: Does the part need to meet specific regulatory requirements, such as FDA approval?
– Size and Load: What are the weight and size specifications?
Each mold development project is unique, and due to the complexity involved, mold creation is often one of the more significant costs of bringing a new product to market. At kitchenbathsilicone, we work closely with clients to minimize costs and streamline the process, including modifying existing molds when possible.
