The field of rubber and elastomer compounding is continually evolving, driven by the need for materials with improved mechanical properties, greater durability, and more efficient processing. A key innovation at the heart of this advancement is the use of Vinyl-Terminated Polydimethylsiloxane (VPDMS). NINGBO INNO PHARMCHEM CO.,LTD. is a leading provider of this versatile chemical, enabling compounders to achieve new levels of performance and flexibility in their elastomer formulations.


VPDMS plays a critical role as a base polymer in the production of high-performance silicone rubbers, including both room temperature vulcanizing (RTV) and high-temperature vulcanizing (HTV) systems. Its terminal vinyl groups are highly reactive, facilitating cross-linking reactions with hydrogen-containing silicones in the presence of platinum catalysts. This reaction is the cornerstone of addition-cure silicone elastomers, leading to materials with exceptional tear strength, tensile strength, and elongation. By allowing for precise control over the cross-link density, VPDMS helps create elastomers with tailor-made hardness and elasticity for diverse applications. For those looking to buy vinyl functional silicone for their compounding needs, our product offers unparalleled quality.


Beyond its role as a primary polymer, VPDMS also functions as a powerful modifier and diluent in rubber formulations. It can be used to enhance the processability of large molecular weight or high-viscosity silicone rubbers before vulcanization. This leads to smoother processing, reduced manufacturing defects, and ultimately, higher quality finished products. NINGBO INNO PHARMCHEM CO.,LTD. provides VPDMS with varying viscosities and vinyl content, offering flexibility to meet the specific demands of different compounding challenges. Our standing as a reliable vinyl silicone oil supplier China is built on a foundation of consistent product excellence.


The ability of VPDMS to improve both the physical properties and the processing characteristics of elastomers makes it an indispensable component for innovative rubber compounding. Whether you are developing seals, gaskets, molded parts, or specialized industrial components, leveraging high-quality VPDMS can significantly enhance your product's performance and market appeal.
