The performance characteristics of silicone rubber are largely dictated by the additives used in its formulation. Among these, reinforcing fillers play a critical role in enhancing mechanical properties. Traditionally, precipitated silica and carbon black have been the go-to options. However, advancements in material science have introduced sustainable alternatives, with rice husk silica emerging as a prominent player. At NINGBO INNO PHARMCHEM CO.,LTD., we champion the use of rice husk silica, particularly our SR2200 grade, for its exceptional reinforcing capabilities in silicone rubber applications.

Rice husk silica, also known as bio-based white carbon black, is a testament to innovative recycling and material utilization. By processing agricultural waste, we create a high-value chemical additive that offers a competitive edge. Our SR2200, produced from rice husks via a green carbon dioxide acidification method, provides a unique combination of properties that benefit silicone rubber compounding. As a reputable supplier in China, we ensure that this material meets stringent quality standards, offering a reliable solution for manufacturers seeking to improve their product’s durability and resilience.

The primary function of SR2200 in silicone rubber is to act as a potent reinforcing agent. When incorporated into High Temperature Vulcanizing (HTV), Liquid Silicone Rubber (LSR), and RTV-2C systems, it significantly boosts tensile strength, elongation at break, and tear resistance. This improved mechanical integrity is vital for applications demanding high performance, such as automotive components, medical devices, and industrial seals. The micro pearl structure of our bio-based silica ensures excellent dispersion within the rubber matrix, leading to a more uniform and effective reinforcement across the material.

Furthermore, the inclusion of rice husk silica can positively impact the processing characteristics of silicone rubber. SR2200 helps to control viscosity and thixotropy, making the material easier to handle and mold. This stabilization contributes to more consistent product quality and can streamline manufacturing processes. Its utility extends to acting as an anti-settling and thickening agent, which is beneficial for liquid formulations, adhesives, and polymers where maintaining homogeneity and preventing phase separation is crucial. Manufacturers looking for ways to optimize their production efficiency while sourcing high-quality chemical auxiliaries will find our product to be an invaluable asset.

NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing sustainable and high-performance chemical solutions. Our Bio-Based Silica SR2200 stands as a prime example, offering a dual benefit of enhanced product performance and reduced environmental impact. We encourage you to consider this advanced rice husk silica as a superior alternative for your silicone rubber reinforcing needs, and to partner with us for your supply chain requirements in China.
