Food grade silicone tubing is made from imported silicone raw materials, using scientific production processes and intermittent methods to produce raw rubber. It is designed for the high tear resistance and transparency of gas-phase adhesives, the ultra-high and lower hardness of mixed adhesives, and functional mixed adhesives. This product has a wide range of adaptability. Compared to the traditional double two four vulcanization process of silicone tubes and silicone profiles, it has the advantages of high transparency, no odor, no yellowing, and no frost spraying, especially solving the problems of black tube frost spraying and blue product fading.

Food grade silicone is a high-quality transparent food silicone with high transparency and stability. It can withstand high temperatures up to 250 ℃ and does not reduce when heated in a sealed environment. Food grade silicone is made from high-quality silicone (a brand new imported food grade silicone raw material), processed through scientific formula and advanced technology. This product has the characteristics of softness, high temperature resistance, and stability. Today, in the era of healthy eating, food grade silicone has gradually replaced food grade plastics.

Main features:
1. Non toxic, odorless, high transparency, and not yellowing;
2. Soft, elastic, resistant to twisting and deformation;
3. Non cracking, long service life, cold and high temperature resistance;
4. It has higher tear resistance and superior electrical performance;
5. A silicone tube more suitable for making food machinery;

Performance parameters:
1. Hardness: 45-80 degrees;
2. Elongation rate: 500~700%;
3. Common colors: transparent, white, black, red, green, blue, gray;

Main use:
Mainly used for food molding, chocolate molds, candy molds, precision casting, as well as carbon fiber composite materials, food cake molds, craft ceramics, printing, human organ cloning, household appliances, lighting products, silicone ice grids, silicone pacifiers.

Additional questions:
Causes of bubble formation
1. Raw material issue: It is estimated that transparent white carbon black is impure or mixed with other white carbon black;
2. Coking issues: Uneven mixing of rubber materials, unreasonable filling capacity, and uncontrolled discharge temperature and time.


Solution measures
1: Regarding the issue of raw materials: choose transparent white carbon black with better purity, clean it with a kneading machine, and then refine the transparent adhesive material;
2: Regarding coking process issues: control the kneading temperature and time, extend the original kneading time by 5-10 minutes, and then perform a rubber discharge inspection.

Rubber storage and transportation matters
1. This product is a non hazardous material and should be stored in a sealed and cool place to prevent rain and sunlight exposure.
2. Avoid contact with condensed silicone rubber vulcanizing agents during operation. Amines, sulfur-containing, phosphorus compounds, and some metal salts may also cause non vulcanization of rubber materials.

Performance:
1. Food grade silicone belongs to a type of environmentally friendly silicone, which is non-toxic, odorless, and has high transparency;
2. Soft, elastic, resistant to twisting and deformation;
3. No cracking, long service life, cold and high temperature resistance;
4. Having higher tear resistance and superior electrical performance;
5. Keep it unchanged at room temperature, do not spray frost, do not spit white, do not fade, and leave it in water for a long time without scale or odor;
