Product Description

Introduction to Food Grade Silicone Tube:

Food-grade silicone tube is made of imported silicone raw materials, scientific production technology, and batch method for raw rubber production, aiming at the high tear resistance and high transparency of fumed rubber, the ultra-high and lower hardness of the rubber compound, and the functional mixing This product has a wide range of adaptability. Compared with the traditional two-two-four vulcanization process silicone tube and silicone profile, it has the advantages of high transparency, odorless, no yellowing, no blooming, etc., especially to solve the problem of black hose blooming and blue products fading. Food-grade silica gel is a high-quality transparent food silica gel with high transparency and stability. It can withstand high temperatures up to 200°C and will not be reduced when heated in a sealed environment. Food-grade silica gel is made of high-quality silica gel (new imported food-grade silica gel raw materials), processed by scientific formula and advanced technology. The product has the characteristics of softness, high temperature resistance and stable performance. Today, in a healthy diet, food-grade silicone has gradually replaced food-grade plastic. Common silicone tubes are: medical silicone tubes, food-grade silicone tubes, industrial silicone tubes, silicone special-shaped tubes, silicone tube accessories.

Food grade silicone tube performance:

1. Food grade silica gel is a kind of environmentally friendly silica gel. It is non-toxic, odorless, and has high transparency; silica gel pipes and silica gel materials have stable chemical properties. Except for strong alkalis, hydrofluoric acid does not react with any chemical substances. Chemical properties Good, good electrical insulation performance, not easy to age and weather resistance, soft material, environmentally friendly, non-toxic material, colorless and odorless. The pipes used in daily life will be made of silica gel, which are mainly used in household appliances, medical industry, industrial industry, automobile industry and so on.

2. It will not be yellow when placed at room temperature, will not spray frost, will not spit white, will not fade, and there will be no scale and no peculiar smell in the water for a long time.


Features of Food Grade Silicone Tube:

1. Non-toxic, odorless, high transparency, non-yellowing;

2. Soft, good elasticity, resistance to kink and no deformation;

3. No cracking, long service life, cold and high temperature resistance;

4. Has higher tear strength and superior electrical performance;

5. It is more suitable for making silicone tube for food machinery;

6. High temperature resistance: -60 degrees -200 degrees;

7. Heat resistance: Food silica gel has much better heat resistance than ordinary silica gel. It can be used almost forever at 150°C without performance changes; it can be used continuously at 200°C for 10,000 hours; it can also be used at 250°C. Can be used for a period of time;

8. Weather resistance: ordinary silica gel is rapidly degraded under the action of ozone generated by corona discharge, while food silica gel is not affected by ozone. And for a long time under ultraviolet light and other climatic conditions, its physical properties have only slight changes;

9. Anti-aging, anti-corrosion, silica gel itself has strong inertness.


Food grade silicone tube application range:


1. Medical equipment connecting pipelines, catheters, etc.;

2. Baby bottle straws, catheters, etc.;

3. Bushings and profiles for electrical appliances, etc.;

4. Food tube products;

5. Connecting pipe for food machinery;

6. Water dispensers, coffee pots, connecting pipes and conduits for children's suction cups, etc.

Remarks: The above data is the test result after one molding vulcanization.

Vulcanizing agent C-8, the addition amount is 2%, and the curing condition is 170℃×5min×15Mpa.

The result in the table is the typical data of this type of product, and each batch of products will have a certain deviation.


Quality assurance:

For each of our products, we will design a dedicated test equipment. Every product is an empirical test. Not a random test. This is one of the product test equipment.

Food grade silicone tube product certification:

Mainly SGS environmental protection certification and UL flame retardant certification, 16949 certification, the higher the environmental protection and flame retardant performance, the more favorable products are for export.


Service Introduction:

Pre-sales: Pre-sales will actively communicate with customers detailed information, customer needs, product parameters, quality standards, provide consultation, accept telephone orders and mail orders, provide a variety of convenience and financial services, etc.

In-sale: In-sale provides customers with solutions with the best performance-to-price ratio, proactively track contract signing, delivery of goods, and help customers solve problems.

After-sales:

1. Dissatisfaction caused by the quality of the product itself. We will help customers deal with the problem as soon as possible within the agreed period.

2. If the product cannot be used normally due to man-made reasons. We explain the cause of the problem to the customer, indicating that this type of problem is not covered by our warranty, and then provide other solutions to the customer based on the customer's problem.


Causes of bubbles:

1. Raw material problem: It is estimated that the transparent white carbon black is not pure, or mixed with other white carbon black;

2. Coking problem: the compound is not uniformly mixed, the filling capacity is unreasonable, and the temperature and time of the glue discharge are not well controlled.


Solution:

1. Aiming at the problem of raw materials: select transparent white carbon black with better purity, and then refining transparent rubber after the kneader is cleaned;

2. Aiming at the problem of coking process: control the kneading temperature, control the kneading time, extend the original kneading time by 5-10 minutes, and then discharge the glue for inspection.


Glue storage and transportation matters:

1. This product is non-hazardous and should be sealed and stored in a cool place to prevent rain and sun exposure.

2. Avoid contact with condensed silicone rubber vulcanizing agent during operation. There are also amines, sulfur and phosphorus compounds and some metal salts that may cause the rubber to not vulcanize.
