Liquid Silicone Rubber Product
Liquid silicone rubber (LSR) encapsulation is a process of combining liquid silicone rubber with other materials (such as plastic, metal, etc.) to form composite components. The core principle is to use injection molding technology to inject liquid silicone into the mold and coat it on the surface of the substrate. After heating and curing, the silicone is tightly combined with the substrate to form an integrated structure. The following is the detailed principle of liquid silicone encapsulation:
Material characteristics
Liquid silica gel (LSR): composed of two components, A and B, mixed and crosslinked by heating to form an elastomer. LSR has excellent high temperature resistance, chemical corrosion resistance, insulation, and biocompatibility.
Substrate: It can be plastic (such as PC, ABS, nylon, etc.) or metal (such as aluminum, stainless steel, etc.), and needs to have certain temperature resistance and surface adhesion.
The principle of liquid silicone encapsulation is to use injection molding technology to encapsulate liquid silicone on the surface of the substrate, and to achieve the bonding between the silicone and the substrate through heating and curing. The core lies in material selection, mold design, process parameter control, and the bonding mechanism between silicone and substrate. This process is widely used in fields such as automotive and electronics, and can produce high-performance and high-precision composite components.

The main advantages of liquid silicone encapsulation are:
1. Excellent material properties
High temperature resistance: Liquid silicone can maintain stable performance in the temperature range of -50 ° C to 200 ° C, suitable for high temperature environments.
Chemical corrosion resistance: It has excellent resistance to chemicals such as acids, alkalis, and solvents.
Biocompatibility: Odorless, meets medical and food grade standards, suitable for the medical and food industries.
Insulation: It has excellent electrical insulation performance and is suitable for the field of electronic appliances.
2. High precision and complex molding
Good fluidity: Liquid silicone has fluidity and can fill small details in molds, making it suitable for manufacturing complex shaped products.
Dimensional stability: Low shrinkage rate after curing (usually less than 1%), high product dimensional accuracy.
Smooth surface: After molding, the surface is smooth and does not require additional treatment.
Advantages of liquid silicone products
High production efficiency
Fast curing: Liquid silicone gel solidifies quickly under heating conditions and is suitable for large-scale production.
Automated production: The liquid silicone encapsulation process is easy to achieve automation, improving production efficiency and reducing labor costs.
Environmental Protection and Safety
Environmental Protection: Liquid silicone does not contain harmful substances such as plasticizers and halogens, meeting environmental protection requirements.
Aging resistance: Long service life.
Application principle
The liquid silicone encapsulation process fully utilizes the elasticity of silicone and the rigidity of the substrate, making the product possess the following characteristics:
Sealing: The elasticity of silicone makes it suitable for use in sealing components.
Wear resistance: The wear resistance of silicone extends the product's lifespan.
Insulation: The insulation properties of silicone make it suitable for electronic components.
High temperature resistance: The high temperature resistance of silicone makes it suitable for high temperature environments.
Advantages of liquid silicone gel
Versatility
Sealing performance: The elasticity of liquid silicone makes it very suitable for use in sealing components such as O-rings, gaskets, etc.
Shock absorption and buffering: The elasticity of silicone can provide good shock absorption and buffering effects, suitable for fields such as automobiles and electronics.
Waterproof performance: Liquid silicone encapsulated products have good waterproof performance and are suitable for outdoor or humid environments.
design flexibility
Multiple color options: Liquid silicone can be blended into multiple colors to meet the aesthetic needs of different products.
Soft hard combination: Through encapsulation technology, the combination of soft silicone and hard substrate can be achieved, expanding product functionality.
LOW TEMPERATURE RESISTANCE
It can also maintain good performance in low-temperature environments. This makes liquid silicone products suitable for various low-temperature scenarios, ensuring that the product still has reliable performance under low-temperature conditions.
Excellent adhesion performance
Excellent adhesion performance
Combining with various materials: Liquid silicone can firmly bond with plastics (such as PC, ABS, nylon, etc.), metals (such as aluminum, stainless steel), and other materials.
Mechanical and chemical bonding: Through mold design and surface treatment, mechanical interlocking and chemical bonding can be achieved to ensure bonding strength.
GOOD BIOCOMPATIBILITY
Liquid silicone is a biologically inert material that is non-toxic and non-irritating to human tissue. This good biocompatibility makes liquid silicone an ideal material for making medical devices implanted in the human body, ensuring the health of patients and the safe use of medical equipment.
