Quality LSR Liquid Silicone Rubber & Food Grade Liquid Silicone Rubber Manufacturer

Introduction Liquid Silicone Rubber (LSR) is widely applied in medical, electronics, consumer goods, and industrial manufacturing due to its excellent elasticity, heat resistance, and chemical stability. Traditionally, many LSR materials require post-curing after molding to reduce volatile residues and stabilize material performance. To meet increasing demands for cleaner processing and higher efficiency, Ruihe has developed the 6250 FV Series Non Post-Cured Liquid Silicone Rubber, designed to deliver stable performance without secondary heat treatment. What Is Ruihe 6250 FV Series Non Post-Cured LSR? The Ruihe 6250 FV Series is a specially formulated non post-cured liquid silicone rubber that completes sufficient crosslinking during the primary injection molding process. Molded parts can be used directly after demolding, eliminating the need for additional oven post-curing. Key formulation features include: Optimized platinum-catalyzed curing system Low-volatility, high-purity silicone raw materials Precise formulation and process control The series is designed with VOC content effectively controlled below 0.35, ensuring low odor and minimal volatile residues after molding. Key Advantages of 6250 FV Series High Production Efficiency By eliminating post-curing, the 6250 FV Series shortens production cycles, reduces energy consumption, and improves manufacturing efficiency—especially suitable for automated and high-volume production lines. Low VOC & Low Odor Performance With VOC levels controlled below 0.35, this series significantly reduces odor, fogging, and migration risks, making it ideal for enclosed components and applications with strict cleanliness requirements. Wide Hardness Range The 6250 FV Series is available in a hardness range from 20 to 70 Shore A, allowing flexibility for different product designs—from soft-touch components to structural silicone parts. Stable Mechanical & Thermal Properties Even without post-curing, the material maintains excellent elasticity, tear strength, hardness stability, and long-term heat aging resistance. Improved Product Consistency The elimination of secondary curing variables results in better dimensional stability and reduced batch-to-batch variation. Typical Applications The Ruihe 6250 FV Series non post-cured LSR is suitable for:   Medical and healthcare components Electronic and electrical insulation parts Consumer and baby products Industrial precision molded silicone components   Customization & Technical Support The 6250 FV Series can be customized in terms of hardness, flowability, curing speed, and color. Ruihe provides technical support from material selection through mass production to ensure stable and reliable performance in real processing conditions. Conclusion The Ruihe 6250 FV Series Non Post-Cured Liquid Silicone Rubber combines low VOC performance, a wide hardness range (20–70 Shore A), and high production efficiency. It offers manufacturers a practical solution to simplify processing while maintaining consistent quality and performance.   If need.please do not hesitate to contact Whatsapp/Wechat: 86 13421773611, Email: wendy@ruihesilica.com
