Liquid silicone products and liquid silicone injection molding processes are well known. Liquid silicone products can be seen everywhere from daily household items to large applications in the aerospace industry. Liquid silica gel has its own place in a wide range of application fields and benefits from its superior chemical molecular properties and physical structural characteristics.
The application of liquid silicone in the e-cigarette industry has also been a hot topic in the advocacy of sustainable development industry and the rise of the industry in recent years. E-cigarette products are high-end consumer goods. According to the e-cigarette output value report given by the industry, the global industry scale will reach 260 million in 2019. billion, and the total domestic product exports in the first quarter of 2019 were RMB 6.7 billion. Under the temptation of huge cakes, ranging from e-cigarette sealing ring accessories to the improvement of atomization technology, e-cigarette suppliers continue to seek differentiated manufacturing processes to enhance the selling points and market share of their products.

Liquid silicone exists in the e-cigarette industry in the form of liquid silicone products and liquid silicone encapsulation. It is mainly designed for the appearance of e-cigarettes, including e-cigarette waterproof solutions, e-cigarette anti-fall solutions, and liquid silicone-specific Delicate texture, softness and practicality. In addition, there are atomized oil leakage prevention solutions and environmentally friendly food-grade material applications. The main types of electronic cigarette silicone parts include sealing rings, mouthpiece covers, appearance protective covers, microphone bases, and oil cups. Among them, sealing rings and exterior coatings are common solutions for preventing oil leakage.
Liquid silicone also has good performance in terms of waterproofing of e-cigarettes. The liquid silicone injection molding process uses liquid silicone positioning technology to inject the liquid silicone mixture into the product mold on the precision mold. After vulcanization, the packaging can be completed. Glue finished product. The liquid silicone injection molding process can tightly wrap e-cigarette alloy parts or PC materials, plastic nylon and other materials to achieve waterproof and anti-fall effects.

The problem of oil leakage and oil leakage from the electronic cigarette body has always been a pain point for electronic cigarette products. There are many reasons for oil leakage and oil leakage, including the insufficient precision of the oil leakage prevention seal and human error in operation. Nowadays, most electronic cigarette atomizer base sealing oil rings are applied to liquid silicone sealing rings, which have good sealing performance, are not prone to chemical reactions with substances such as electronic cigarette oil, and are acid and alkali resistant and anti-aging. The application of liquid silicone sealing rings and protective sleeves on electronic cigarette atomizers can effectively prevent oil leakage.

E-cigarettes belong to the tobacco industry and are in the lifestyle and medical category. It is essential that the cigarette holder and other accessories are made of food-grade materials. Since electronic cigarette silicone parts are in close contact with the human body, their food safety requirements are relatively high. At the same time, the requirements for waterproofing and oil leakage are getting higher and higher, and the precision of silicone parts is also getting higher and higher. Liquid silicone rubber is compared to solid high-temperature vulcanized silicone rubber. It is a liquid rubber with good fluidity and fast vulcanization. Safer and environmentally friendly, it can fully meet food grade requirements. Liquid silicone itself is a food-grade raw material, and it can also be used as a medical-grade raw material in the medical industry.

In the market, people's demand for consumer products that are fashionable, beautiful and practical is becoming increasingly high-standard and refined. A hot-selling electronic product has its own selling points and advantages, both in terms of appearance and internal process structure. Most of the early first- and second-generation e-cigarettes used plastic or solid silicone as the outer packaging. Its waterproof performance and hand texture are far from meeting the needs of consumers. Liquid silicone can not only be used as a protective cover for appearance, but its application in baby pacifiers and medical applications also determines its own softness and delicate texture. It has good resilience, excellent hand feel, high transparency, and good physical, kinetic, and mechanical properties. As an electronic cigarette appearance protective cover, it can better prevent falls.
