    Difference between liquid silicone rubber(LSR) and solid silicone

    Liquid silicone rubber and solid silicone are two different forms of silicone materials. They are not only different in appearance, but also in other uses.
    Liquid Silicone Rubber: Liquid silicone rubber is a fluid, gel-like liquid. Commonly used in applications such as injection, dipping, and coating, it can fill and wrap irregularly shaped objects to form a soft, transparent protective layer.
    Solid Silicone: Solid silica gel is a solid material that resembles a dry gelatinous or granular substance. It can be used in applications such as absorbing moisture, filtering impurities, and catalyzing reactions, and is commonly used in desiccants, catalysts, fillers, and other fields.
    Application fields:
    Liquid silicone rubber: Due to its fluidity and transparency, liquid silicone is often used to make various soft protective layers, such as silicone tableware, silicone baking mats, silicone mobile phone cases, sealing layers of electronic equipment, toys, custom silicone molds making, etc.
    Solid silicone: Solid silica gel is mainly used for humidity regulation, moisture adsorption and impurity filtration. It can be used as a desiccant to help maintain the relative humidity of the environment, preventing moisture and corrosion; it can also be used to filter impurities and purify air or fluids.

    Is food-grade silicone all liquid silicone?

    NO,Food-grade silicone can include liquid silicone and solid silicone, depending on what it is used for and how it is applied.
    Liquid silicone: Liquid silicone may be used in some food contact materials, such as making silicone food molds, silicone candy molds, silicone chocolate molds, silicone candle molds, etc. Liquid silicone can be poured into molds, formed into the desired shape, and then hardened into a solid to make food.
    Solid Silicone: Food-grade solid silicone is usually used as a food preservative or humidity regulator to extend the shelf life of food. These solid silica particles absorb moisture from food, thereby slowing down the spoilage process. They are usually placed in food packaging, but do not come into direct contact with food.
    Silicone products are odorless. Silicone is an inorganic compound that usually does not emit a strong odor or taste. This makes silicone widely used in many applications, including food packaging, medical devices, baby products and other fields that come into contact with the human body.

    How is the processing different?

    custom silicone service:
    Silicone Compression Molding: Solid silicone is usually molded by placing silica gel granules or powder into a mold and applying pressure to solidify it into the desired shape. This method is suitable for the production of various solid silica gel products, such as humidity regulators, filter materials, etc.
    Silicone Injection molding: Liquid silicone is usually manufactured by injection molding. Pour liquid silicone into a mold or container of the desired shape and wait for it to harden into a solid. This method is suitable for making transparent and soft products, such as mobile phone cases, seals and so on.
