Legensilico | Reliable Silicone Sleeve Manufacturer in China
Legensilico’s engineered silicone sleeves are made for different purposes. Whether it’s for electronics, kitchenware, medical, and automotive industries, silicone sleeves have their important roles. For more than two decades in manufacturing, our team of experts know exactly how to make your ideas work perfectly on your specific market.
In terms of curing, there are two common types of silicone material we use. One is the platinum-cured variants which offer uncompromised purity. This is used to make silicone sleeves for baby bottles, syringe, and food handling essentials, meeting USP Class VI standards. The other one is the peroxide-cured option. Silicone sleeves made from this material are much more cost efficient. They can withstand high temperature and oil or chemical exposure, that’s why silicone sleeves like this are perfect for automotive wiring and industrial hoses. Our fire-retardant silicone sleeves comply with MIL-DTL-9240, resisting 2000oF flames for 30 minutes. But most of all, our silicone sleeves undergo rigorous testing, passing FDA’s CFR 21 Part 177.2600 checks, LFGB’s sensory evaluations, and CE’s biocompatibility assessments. In our factory, we also use advanced 3D molding to ensure that the sleeve perfectly fits to where it must be placed. To minimize waste, we follow eco-friendly production. Whether daily use or harsh industrial settings, our silicone sleeves deliver consistent, safe performance.
