LSR Liquid Silicone Rubber Food Grade Low VOC No Post Cure for Food Sealing Gasket with Excellent Tear Resistance & Elasticity

A two-part addition cure liquid silicone rubber (LSR) model 6250-50FVAB is suitable for various food contact production scenarios, capable of helping manufacturers complete high-precision one-shot injection molding. The finished product features uniform and stable crosslinking, completely eliminating the need for secondary post-baking processes. In actual use, the product's VOC content is below 0.35%, with no small molecule leaching, strictly meeting FDA and LFGB food contact safety standards. It has currently become a high-quality and environmentally friendly upgrade option for major manufacturers to replace traditional post-curing food-grade silicone rubbers.

The core gaps lie in production cost, VOC level and finished product quality. Traditional food-grade LSR requires mandatory secondary high-temperature baking to cut volatile residues, which brings high electricity cost, long production cycle, and risks of yellowing and deformation on finished goods. RUIHE 6250-50FVAB adopts low VOC formula with volatile content less than 0.35% and no small molecule precipitation. It meets international food safety standards without post-curing, greatly saving production time and energy costs.

Fully applicable for mass injection molding production. This transparent food-grade LSR passes FDA and LFGB certification, with ultra-low volatile content and zero harmful precipitation. The finished silicone products are odorless, high-temperature resistant and easy to clean, which is the mainstream material choice for global kitchen utensils, baby feeding tools and food sealing accessories.

There is no negative impact on product performance at all. After one-time curing, 6250-50FVAB forms a dense and stable molecular crosslink structure. Its anti-yellowing, anti-aging and corrosion resistance are better than traditional post-curing silicone, with no volatile substances separated out during long-term use. It can keep stable performance for long-term food and medical application scenarios.

Full customization service is available. We can adjust hardness (20~70 Shore A), appearance (transparent/solid color), colloid viscosity and curing speed to fit different high-speed injection equipment. Custom functional formulas such as antibacterial, high anti-yellowing and wear-resistant LSR are supported for food, medical and daily necessities industries.
