YEJIA Optical Technology (Guangdong) Corporation

  In today’s high-performance manufacturing landscape, materials must deliver precision, durability, and adaptability. One material that consistently meets these demands is Liquid Silicone Rubber (LSR). Known for its exceptional resilience and flexibility, LSR has become a preferred choice in industries ranging from medical devices to automotive engineering. Manufacturers like Yejia Silicone are driving innovation by offering advanced LSR solutions tailored for complex applications. LSR is a flexible material that starts as a liquid and turns solid through a quick cure. Unlike thermoplastic elastomers (TPE) or fluorocarbon rubbers (FKM), which can break down under heat or lose shape over time, LSR holds strong. It blends top-notch thermal stability, biocompatibility, and bounce-back elasticity. These traits make it perfect for high-stakes work where parts can't afford to quit. In fast-moving industries like medical devices and cars, precision matters a lot. One small flaw can le...

  In the rapidly evolving world of lighting technology, precision and efficiency are everything. From LED streetlights and automotive headlamps to architectural and industrial lighting, the demand for high-performance optical components continues to grow. One innovation leading this transformation is the silicone optical lens —a versatile solution designed to enhance light control, durability, and overall system performance. What Is a Silicone Optical Lens ? A silicone optical lens is a specialized lens made from high-quality liquid silicone rubber (LSR). Unlike traditional glass or plastic lenses, silicone lenses offer superior flexibility, thermal stability, and optical clarity. These properties make them ideal for modern LED lighting systems where performance and longevity are critical.   Why silicone lenses? Silicone optics are increasingly used where thermoplastics (PC, PMMA) hit their limits. Compared with PC/PMMA, optical-grade silicones typically offer: Hig...

 Silicone cross-slit valves have become a go-to solution for controlled dispensing and one-way flow systems across multiple industries. Known for their flexibility, durability, and precision sealing, these valves are designed with a cross-shaped slit that opens under pressure and reseals instantly when pressure is released. This simple yet effective design ensures leak-proof performance, contamination prevention, and consistent flow control. In this article, we’ll explore the top applications of silicone cross-slit valves and provide a practical guide to selecting the right one for your needs. What Is a Silicone Cross-Slit Valve? A silicone cross-slit valve is a one-piece elastomeric component made from high-quality silicone rubber. It features a pre-cut cross-shaped opening that remains closed under normal conditions. When internal pressure is applied, the slit opens to allow fluid or air to pass through, and then automatically closes once the pressure drops. Key Features: ...
