Liquid Silicone Rubber Injection Molding Parts Application | Fox Mold
Application of liquid silicone rubber injection molding parts
Liquid silicone is developing rapidly, with higher grades and high product technology content. The domestic liquid silicone market will grow to 2.099 billion yuan in 2022, with the medical care field having the largest market share, accounting for 59%, followed by electronic appliances and daily necessities, accounting for 59%. 18% and 13% respectively. Low VOC, self-adhesive type is widely used.
Liquid silicone is used in 3C electronics, automobiles, medical care, infants and children, personal care, and daily necessities. It has the advantage of easy processing and molding, and can eliminate mixing, preforming, post-processing and other processes. It is easy to automate and can save energy. and labor force, the production cycle is short and efficient.
Food-grade liquid silicone is environmentally friendly and non-toxic. Because of its high food safety, it also occupies a leading position in the application of baby products and medical products.
The shell protective cover made of LSR liquid silicone rubber is colorless and odorless and is more suitable for direct contact and use with human skin. LSR liquid silicone itself has very good physical ductility and will not cause personal injury due to impact and breakage. Liquid silicone is resistant to high temperatures, acid and alkali environments.
Liquid silicone itself has excellent transparency, tear strength, resilience, anti-yellowing, thermal stability, water resistance, good air permeability.
Liquid silicone gel (LSR) technology has the characteristics of precise micro-injection, which has made it more and more popular in recent years. The waterproof seal manufacturing of electronic 3C products uses LSR injection molding technology, cold runner design, and reasonable runner distribution to produce precision electronic silicone products.

LSR has properties such as durability, tensile strength, high thermal stability, fatigue resistance and tear resistance, making it an excellent choice for components used under the hood of automobiles. LSR can also be molded directly onto plastic or metal parts, and many OEMs like to use liquid silicone rubber to manufacture a wide variety of independent parts, including O-rings, buttons, components, gaskets, and wire harness assemblies.
Durability: Liquid silicone rubber parts can withstand extreme temperatures, making them ideal for components under car hoods and near engines. Parts made by injection molding of liquid silicone rubber are flame retardant and will not melt, which is a serious problem for parts made by plastic injection molding methods.
Chemical Properties: Liquid silicone rubber is resistant to water, oxidation and certain chemical solutions such as acids and alkalis. High Temperature Resistance: Compared to other elastomers, molded silicone can withstand a wide range of high/low temperature extremes. For example, Dow Corning's continuous-use Silastic LSR is stable over a temperature range of –60°C to +180°C. Mechanical properties: Liquid silicone rubber has good elongation, high tear and tensile strength, excellent flexibility and a hardness range of 5 to 80 Shore A.
Electrical properties: Liquid silicone rubber has excellent insulating properties, which makes it an attractive option for many electrical applications. Silicones can operate at higher and lower temperatures than conventional insulation materials. Transparency and Pigmentation: Liquid silicone rubber is naturally transparent, and this property makes it possible to produce colorful, customized injection molded products.

At the current development level of medical technology, liquid silicone products cannot be underestimated. Nowadays, medical liquid silicone rubber products such as medical liquid silicone rubber air bags, medical liquid silicone rubber tubes, liquid silicone rubber ties, and liquid silicone rubber pads have been put into the market, and medical-grade liquid silicone rubber has been put into use.
In the medical industry, in order to meet the increasing medical needs, the research direction of liquid silicone mainly focuses on three aspects: surface modification, blending modification and application research. The material has coagulation properties, good stability, good clinical usability, no allergic reactions, and product stability and performance are higher than ordinary silicone rubber and food-grade silicone rubber.
As China becomes the world's factory, the consumer market for liquid silicone has also shifted from Western developed countries to emerging markets represented by China. More and more silicone product manufacturers have begun to process various silicone parts and sell them to countries including China. within the global market. Medical silicone dominates.
Liquid silicone products have been widely used in the medical industry due to their excellent physical properties and excellent chemical and heat resistance. In addition, medical-grade liquid silicone has many advantages, such as biocompatibility, easy sterilization, and transparency. And the material feels soft against the skin, making it an obvious choice for medical devices that contact with the body. Fox Mold produces a wide range of products for the medical industry, including face masks, valves, catheters, seals, balloons and other miscellaneous items.
