The main differences between liquid silicone and solid silicone are reflected in the following aspects:
Physical state and liquidity:
Liquid silicone: In a liquid state, it has fluidity.
Solid silicone: In a solid state with no fluidity.
Transparency and Odor:
Liquid silicone: High transparency, no odor, and the product usually has a glue injection port.
Solid silicone: The transparency is relatively low, and there is a smell of curing agent or other curing agents. The product usually does not have a glue injection port.
Material characteristics and applications:
Liquid silicone: It is a food grade material with high transparency and safety. During molding, no auxiliary materials such as vulcanizing agents are added, and it is sealed and fed into shape. Mainly used for baby products, kitchen supplies, and medical supplies, it can come into direct contact with food and the human body.
Solid silicone: It is a transparent and environmentally friendly material that requires the addition of a vulcanizing agent to accelerate the vulcanization molding time during molding, and open mold feeding for molding. Usually used in daily necessities, industrial miscellaneous parts, and automotive components.
Forming process:
Liquid silicone: usually produced using injection molding machines, with a simple process flow, high product accuracy, and high yield.
Solid silicone: The raw material is solid, which is mixed by a mixer and cut into a size and thickness suitable for the product and mold. It is then placed in the mold and molded at a certain temperature under a pressure forming machine.
Safety and Environmental Protection:
Liquid silica gel: more safe and environmentally friendly, can fully meet the food level requirements, and has excellent tear resistance, resilience, yellowing resistance, thermal stability, heat resistance and aging resistance.
Solid silicone: also environmentally friendly, but mainly used for non food contact purposes.
In summary, there are significant differences between liquid silicone and solid silicone in terms of physical state, transparency, odor, material characteristics, molding process, safety and environmental protection. These differences give them their respective advantages and applicability in different fields and applications.
