Liquid silicone products are a kind of environmental protection, low-carbon and green products processed and molded with silicone as raw material. The main processing techniques are injection molding, extrusion molding and molding. Silicone has irreplaceable superior performance of other soft rubber, such as: good elasticity and water and moisture resistance, resistance to acid, alkali and other chemical substances, does not contain any harmful substances, while not easy to deformation.

 

Advantages:

Non-toxic to human body, odorless and tasteless.

Good transparency, can be disinfected.

Performance

Good touch, elasticity, anti-aging properties.

good high temperature resistance, thermal stability (continuous working temperature up to 180°C)

good low temperature performance (still soft at -50°C).

Excellent electrical insulation, no harmful substances will be produced when burning

 

 

Second, the application range of liquid silicone rubber

liquid silicone rubber can be used for trademarks, silicone products, pacifiers, medical silicone supplies, coating, impregnation, infusion, etc. Used in crystal glue, polyurethane, epoxy resin molding mold, injection molding process, cake mold and other silicone products, widely used in the electronics industry as electronic components of moisture-proof, consignment, insulation coating and potting materials, electronic components, and assemblies to play dust, moisture, shock and insulation protection. Such as the use of transparent gel potting electronic components, not only can play shockproof and waterproof protection but also can see the components and can detect the failure of the components with a probe, to replace, damaged silicone gel can be potted again to repair. It can also be used to make molding molds for plaster, wax, epoxy resin, polyester resin, polyurethane resin and low melting point alloy, etc. It is used in high-frequency embossing of artificial leather, modeling of face and sole of shoes, manufacturing of arts and crafts, ceramics, toy industry, furniture, replication of electronic components of household appliances, and molding of plaster and cement materials, molding of wax products, manufacturing of models, molding of materials, etc.

 

Third, the characteristics of liquid silicone 

Liquid silicone molding and ordinary injection molding products injection characteristics difference.

liquid silicone rubber is a thermo setting material.

Rheological behavior as follows: low viscosity, rapid curing, shear thinning, higher coefficient of thermal expansion.

very good fluidity, low requirements for clamping force and injection pressure, but high requirements for injection accuracy.

Exhaust design is relatively difficult, some products need to be designed with sealed vacuum structure, which requires high precision for the mold.

The barrel and pouring system need to design the cooling structure, while the mold needs to design the heating system.
