Liquid Food Grade Silicone

Food grade liquid silicone resin is also commonly called liquid FDA silicone resin, FDA liquid silicone resin, FDA rubber liquid, which is a soft, high-purity and platinum-cured silicone rubber. Liquid silicone rubber products are manufactured through liquid silicone rubber injection molds and RTV-2 molds.

Liquid food grade silica gel is completely non-toxic and odorless, and does not contain any chemical residues.Products made of these materials can contact the human body directly or indirectly, such as baby silica gel pacifier, silica gel bottle, silica gel kitchen utensils, silica gel plate, silica gel bowl, etc.

Food-grade silica gel is a product that can enter the mouth and body without causing discomfort and sensitivity, and can meet various testing and certification standards.Ordinary silica gel does not meet this standard.

So how to identify food-grade silicone through a simple method?Food-grade silica gel generally has the following phenomena,

1. Whether the stretch spring returns to its original state;

2. Whether there is white phenomenon in long-term stretching;

3. Strong stress ability can be restored immediately after long-term pressing;

4. Good hand feel and certain toughness strength;

5. See if there is any whiteness after stretching.

LSR is an inorganic substance that is clean, odorless, and plasticizer-free. LSR is not only waterproof, but also resistant to chemical corrosion, such as oxidation acids and alkalis.

LSR is resistant to bacterial growth, does not pollute or corrode other materials, and does not burn to form water vapor and carbon dioxide. It is halogen-free and non-toxic.

LSR can be sterilized by steam sterilization, ethylene oxide, gamma, electron beam, etc.

LSR can meet all food grade and medical requirements or certifications, such as USP Class VI, FDA 21 CFR 177.2600, BfR XV, etc.

Liquid silicone rubber-LSR has a very low viscosity, which can be molded by casting or casting, and can also be used in liquid injection molding (LIM) equipment or cast into semi-finished silicone rubber sheets. Because it is very safe in contact with the human body and meets food-grade requirements, it is widely used to make food-grade products. It also has high thermal stability and flexibility at low temperatures, high transparency, and is easy to be colored.

Advantages of liquid silicone rubber

Liquid silicone rubber not only has good high and low temperature resistance, but also has good mechanical properties, low compression setting, high elongation, high tear strength and tensile strength.

It has also been proven in a large number of extensive tests that liquid silicone rubber has excellent compatibility with human tissues and fluids. Compared to other elastomers, LSR is resistant to bacterial growth and does not stain or corrode other materials.

Liquid silicone rubber facilitates injection molding and processing

Due to the low viscosity of LSR, we can easily pump it to the vulcanization equipment through pipelines and pipes for processing. The process is simple and low cost, and it is widely used in medical and food fields.

Liquid silicone rubber has a certain fluidity, easy to flow into a very thin cross section, which makes the mold design simple.Usually the mold surface also does not need high polishing, also does not need to design the special Angle to facilitate the mold release, virtually reduces the mold manufacturing cost, and the yield rate is high, also reduces the product cost, deeply welcomed by the market.

In addition to the basic equipment for manufacturing molds, such as CNC machine tools, milling machines, grinding machines, we also have imported high-precision CNC equipment and related product testing equipment.We can design and manufacture precision rubber mold for customers, and customize the production of all kinds of high quality food grade silicone products.
