Often hear customers ask us whether we have injection silica gel, liquid silica gel we have, but the liquid silica gel itself can not injection molding, only injection molding.The customer asked whether the liquid silicone can be injection molded, is the understanding of thermoplastic and thermosetting is not enough, the new best to introduce the difference between the two, and then tell the difference between liquid silicone injection molding process and plastic injection molding.

    Thermoplasticity is when a material is plasticized at high temperature into a liquid that can flow, allowing it to form and return to a solid at room temperature.If the temperature is high, it is plasticized, so it can be recycled again and again.Such products mainly include PVC, PE, ABS and other plastics.Thermosetting means that the material changes from a liquid or paste crop to a solid at high temperature, remains solid at low temperature, and then at high temperature it does not become a liquid or paste, but remains the original solid state.Until high temperature damage to the structure of the product, so that it occurs chemical reaction, decomposition into other objects, such as rubber epoxy resin and other materials are thermosetting materials.

    Injection molding liquid silica gel itself is liquid or paste, the group of ingredients by vinyl silicone oil and hydrogen silicone oil silica black, catalyst, delay agent and other materials, high temperature under the action of the catalyst, liquid silica gel itself chemical cross-linking reaction, curing into silicone rubber.It's a chemical reaction. It's irreversible.

Because liquid silica gel will react at high temperature, the flow channel system of injection molding equipment needs to use cold flow channel, which is the main difference with injection molding equipment.Injection molding machine is a hot runner, liquid silica gel in the runner will be raw curing, so can not use injection molding machine to process liquid silica gel.

    The above is the liquid silicone injection molding rather than injection molding reasons.So when you do not know what kind of silicone products you need to buy, you can pay more attention to our new best silicone, or online consulting customer service, we will provide you with more and more complete liquid silicone information.
