Silicon dioxide for Food-Grade Silicon Rubber from China Supplier
Food-grade silicon rubber is widely used in the food and medical industries due to its excellent physical and chemical properties. Silicon dioxide is widely used as a reinforcing filler for food-grade silicon rubber. In this article, we will discuss the characteristics of silicon dioxide for food-grade silicon rubber and its various applications.
Product Characteristics:
1. High Purity: Silicon dioxide for food-grade silicon rubber is manufactured using high-purity raw materials and is subjected to strict quality control measures to ensure minimum impurities.
2. High Reinforcement: Silicon dioxide is used as a reinforcing filler in food-grade silicon rubber. It provides excellent reinforcement and enhances the mechanical properties of food-grade silicon rubber, such as tensile strength, elongation, and tear strength.
3. Easy dispersion: The silicon dioxide used in food-grade silicon rubber has excellent dispersibility in the rubber matrix, which ensures the uniform distribution of the filler throughout the rubber compound.
