Silicone sealing ring performance:

Silicone tube is a kind of rubber with a wide range of special comprehensive properties. It has excellent electrical insulation properties, aging resistance, chemical stability, oxidation resistance, weather resistance, radiation resistance, physiological inertness, good air permeability, high and low temperature resistance, and can be used in Long-term use at -60℃~250℃. It can be widely used as a good electrical insulation sealing and liquid conveying material in aviation, electronics, petroleum, chemical, machinery, electrical appliances, medical, oven, food and other industrial sectors. Performance high and low temperature resistance, oil resistance, non-toxic and tasteless, etc. The operating temperature range of the silicone tube can be from -100°C to 350°C. It has excellent heat-resistant oxygen aging, ozone aging resistance, light aging resistance and weather aging resistance; it has good electrical insulation. Silicone rubber is non-toxic and tasteless, and is widely used in medicine. Use precision representative, oil pipeline, household appliance sealing, drinking water pipeline sealing, medicine, etc.


Features of Silicone Sealing Ring:

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

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

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 under ultraviolet light and other climatic conditions for a long time, its physical properties have only slight changes.

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

10. Surface properties: combing water, not sticky to many materials, can play a role in isolation.

11. Electrical properties: When damp, water or temperature rises, the change is small. Even if the silicon dioxide generated by short-circuit burning is still an insulator, this ensures that electrical equipment continues to work, so it is most suitable for making wires, cables, and lead wires.


Application range of silicone seal:


1. Transportation: Application in shipbuilding industry.

2. Radio, electrical machinery: in the telecommunications industry.

3. Application in instrument and instrument industry.

4. Application in the aviation industry.

5. Suitable for home appliances, lighting, medical equipment, etc.

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.

Silicone seal 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.
