Applications
Ruihe New Materials food grade non-post cure LSR is a high-end low VOC liquid silicone rubber optimized for global mass production.
Different from traditional silicone rubber that requires secondary post-curing, this one-shot molding silicone material achieves full physical performance and food safety compliance after primary molding without secondary baking.
Featuring ultra-low volatile content, non-precipitation and anti-yellowing, it effectively solves common difficult points of conventional LSR such as high energy consumption, low yield and residual substances.
With excellent biocompatibility and non-toxicity, it is widely applied for food contact utensils, baby products and medical disposable supplies in the global market.

Frequently Asked Questions
Q: What is the difference between non-post cured LSR and traditional secondary curing LSR?
The core differences lie in production process, VOC content and product yield. Traditional food-grade LSR requires mandatory secondary post-curing to reduce VOC and eliminate residual substances, leading to high energy consumption, low efficiency, and risk of yellowing & deformation. Ruihe non-post cure liquid silicone rubber (LSR) adopts advanced one-shot molding formula with ultra-low VOC and zero precipitation. It meets FDA and LFGB food safety standards without post-treatment, serving as an upgraded LSR material.
Q: Does the product comply with food contact safety standards and can it be used for tableware and baby food tools?
Fully compliant and applicable. As a certified food grade liquid silicone rubber, our product has passed FDA (USA) and LFGB (Germany) authoritative food contact safety certifications. Featuring ultra-low VOC, zero harmful precipitation and excellent biocompatibility, the finished products are high-temperature resistant, easy to clean and odor-free. It is the mainstream choice for global kitchenware, baby feeding tools and food fresh-keeping products.
Q: Will the non-post curing process affect the service life and weather resistance of the product?
No negative impact at all. Optimized with upgraded formula and technology, this non-post cure LSR forms a dense and stable molecular structure after one-time curing. It delivers better anti-yellowing, anti-aging, weather and corrosion resistance than traditional post-curing silicone rubber, with negligible performance attenuation and no residual small molecules. It is durable and crack-resistant for long-term use, fully meeting the long-service standards of high-end global food and medical products.
Q: Are customized parameters supported? What specifications can be customized?
Full custom LSR customization is available. We can adjust hardness (30-80 Shore A), appearance (high transparent / solid / color), colloid viscosity and curing speed to adapt to different automated processes including high-speed injection molding and precision extrusion. Custom functional formulas suchs as low VOC, antibacterial, high anti-yellowing and wear resistance are supported to meet high-end production demands for food, medical and smart wearable industries.
Q: What is the mass production delivery cycle? Are sample tests available?
As a professional non-post cure LSR manufacturer, we own three standardized production bases with sufficient capacity and stable supply chain. Stock food grade liquid silicone rubber can be delivered within 48 hours, and customized functional formula products take 3-7 working days. Free sample testing, formula debugging and process adaptation technical support are provided to help clients realize mass production efficiently.
