Liquid silicone rubber (LSR) is a new type of silicone rubber material that is non-toxic, tasteless, and has excellent weather resistance and chemical inertness. It is one of the high-grade silicone rubber products that have developed rapidly in recent years. This type of silicone rubber has low viscosity (with certain fluidity and non-formability before vulcanization), and can be fed using metering mixing equipment. It is mixed and injected using a dedicated injection molding device, and then quickly vulcanized to form a molded product. Liquid injection molding silicone rubber has many advantages over traditional materials: short molding cycle, high degree of automation, low vulcanization temperature, no by-products during the vulcanization process, high precision of the resulting product, no need for trimming, long product life, etc. It has become a popular synthetic rubber material and a substitute for high-end applications.

characteristic
Excellent transparency, tear resistance, resilience, anti-yellowing, thermal stability, water resistance, good breathability, heat aging resistance and weather resistance, moderate viscosity, easy to operate, high transparency of the product, allowing for the detection of defects such as bubbles in the mold-infused material, linear shrinkage rate ≤0.1%, and precise replication of product dimensions.

Typical liquid silicone rubber products commonly manufactured include:

Maternal and baby products
Disposable pacifiers, silicone bottles, soothers, teething toys, breast pads, breast pump accessories, etc

Medical supplies
Laryngeal mask, urinary catheter, negative pressure ball, face mask, mask cuff, eye mask, silicone nasal mask and various waterproof rubber seals

Electronic products
3C products, waterproof rubberized phone card holder, silicone phone case, waterproof sealing rubberized cover, etc

Auto parts
LED high-transparency lamp, spark plug, wire harness, anode and cathode plate sealing, O-ring, etc
