What Is Liquid Silicone Rubber?

The odorless and tasteless attributes of liquid silicone rubber (LSR) seamlessly integrate with its inherent resistance to molds and bacteria, forming a safety barrier against undesired contaminants. LSR’s hydrophobic nature, which repels moisture, coupled with its easy-clean properties, establishes a protective shield to preserve the integrity of your food-related products.We employ a comprehensive range of high-quality, food-grade elastomers. To ensure a continuous supply of certified materials, we partner with reputable suppliers globally. By thoroughly assessing your project’s timelines, cost objectives, and understanding your product specifications and performance requirements, our experienced professionals deliver a customized solution to meet your specific needs.

Applications of Food-Grade Liquid Silicone Rubber:

Food-grade LSR finds extensive applications in various settings, ranging from households and commercial establishments to hospitals and educational institutions. It is particularly suitable for situations requiring FDA-approved materials or superior resistance to chemical and bacterial contamination. Some of the products crafted using food-grade LSR include:

  1. Baby Care Products: Including bottles, pacifiers, eating utensils, beverage containers, dispensers, and food storage items. These items demand a combination of safety and durability.


  1. Cookware and Baking Tools:Such as cooking utensils, oven mitts, baking cups, molds, and ice cube trays. Food-contact products made with LSR exhibit longevity and resilience to extreme temperatures, surpassing the performance of traditional plastics.


  1. Industrial Components: Valves, membranes, gaskets, and seals exposed to food in various settings, from home storage solutions to industrial machinery involved in food processing, transportation, and preparation. LSR’s attributes, including ease of sterilization and low creep, make it an ideal choice for critical applications.


These examples highlight just a fraction of the potential applications for food-grade liquid silicone rubber. Ongoing research and development continually introduce new products and possibilities.As a leading manufacturer in the LSR industry, we provide innovative solutions to address your unique challenges.
