Silicone tubing is more used in the transportation, automotive and shipbuilding industries, in the automotive industry. It is mainly a silicone tube used for water cooling and intercooling systems of automobile engines.

Although the silicone tube is an industrial silicone tube, the requirements for quality and performance are also very strict. The application of silicone tubes in the industry is also used in many important systems, and they play a very important role, so the product performance requirements for silicone tubes are also very strict.

Silicone tube is a kind of connection needs that can meet the needs of some large equipment, as well as the needs of catheters. This silicone tube has high elasticity, high elasticity, compression resistance, and long-term use without deformation. At the same time, it can also play a flame retardant role. The silicone tube that is widely used now is made of imported silicone. All are non-toxic, odorless, environmentally friendly, and have the excellent characteristics of high transparency.

Compared with ordinary rubber tubes, silicone tubes have better heat resistance. They can be used in a high temperature environment below 150 degrees without any change in performance, and can still be used in a high temperature environment of 200 degrees Celsius. The effect of using 10,000 times has not changed any performance, so more and more applications are now using large-diameter silicone tubing to replace the original rubber tubing. This change has also increased production security several times. Large diameter silicone tubing has strict requirements.

Silicone tube has excellent electrical insulation properties, aging resistance, chemical stability, oxidation resistance, corrosion resistance, radiation resistance, physiological inertia, good air permeability, high and low temperature resistance, and can be used for a long time at -60℃～250℃.

Therefore, silicone tubes are also widely used in modern industries and daily necessities such as aviation, electronics, chemicals, machinery, and electrical appliances. 
 
With the wide use of silicone tubes in our daily life, people pay more and more attention to the choice of silicone tubes. So, how do we choose a good silicone tube in our daily life? 
 

1. Distinguish from smell: Good silicone tubes are generally free of pungent odor, environmentally friendly, non-toxic, and have good texture.
2. Distinguish from brightness: good silicone tube has better permeability, high color firmness of silicone tube, and the natural color of silicone tube can also be adjusted according to the user’s needs.
3. Distinguish from elasticity: Good silicone tubes generally have better toughness. When we pull hard, if white spots appear, it is a poor quality silicone tube.
4. Color: Generally, the silicone tube is colorless and transparent except for the customizable color. If the color changes seriously after long-term use, the quality is poor. 

Of course, in addition to the above four identification methods, if you want to quickly and easily choose a good silicone tube, the best way is to choose a well-known brand of silicone tube.Linhai Haihua Rubber & Plastic Products Co., Ltd. was founded in 1980. It is a professional manufacturer of all kinds of automobile rubber tubes and rubber&plastic parts. Since 1989, it has become a formal supplier for Dongfeng Motor Company.

Silicone tube is a kind of special rubber with a wide range of comprehensive properties. It has excellent electrical insulation properties, aging resistance, chemical stability, oxidation resistance, corrosion resistance, radiation resistance, physiological inertness, good air permeability, high and low temperature resistance, and can be used in -60℃～250℃ for long-term use. Therefore, it is widely used in aviation, electronics, petroleum, chemical industry, machinery, electrical appliances, medical, oven, food and other modern industries, defense industries and daily necessities. Before the corrosion-resistant silicone tube appeared on the market, people used more rubber tubes for use, and the emergence of silicone tubes gradually replaced rubber tubes. Silicone tube is a new type of silicone tube that is more advanced and more environmentally friendly and healthy that people have discovered in the development process of industrial production. In the past, people’s reliance on rubber pipes can be said to be very large. Even now, there are still many factories using rubber pipes, but in the future, corrosion-resistant silicone pipes will inevitably replace rubber pipes and become the mainstream of industrial production.

Corrosion-resistant silicone tube is a kind of imported silicone, which is made by advanced scientific production technology, and corrosion-resistant silicone tube is a kind of silicone tube with strong corrosion resistance, which is more corrosion-resistant than ordinary silicone tube. better. The rubber tube also has the performance characteristics of corrosion resistance, so it is possible to compare the two to find out what is the difference between the corrosion-resistant silicone tube and the corrosion-resistant rubber tube, and what are the differences between the two?

Judging from the material of the most basic raw materials, the corrosion-resistant silicone tube is a completely odorless, non-toxic, high-transparency, and flexible silicone tube, while the rubber tube has a pungent smell. The most advanced production technology can not be eliminated, so from this aspect, the silicone tube is more environmentally friendly than the rubber tube. Moreover, the flexibility of the corrosion-resistant silicone tube will be better, and the mechanical properties of the rubber tube will be better.

In terms of corrosion resistance, the corrosion resistance of silicone tube is better than that of rubber tube. Of course, relative to corrosion resistance, it is related to the use environment and method of use of the product. There are no specific indicators for the specific use of this. Both have good corrosion resistance, of course, the relative corrosion resistance of silicone tube will be better. Regardless of the environment, the corrosion resistance of the silicone tube maintains good test data.

In the future industrial production, the corrosion-resistant silicone tube will inevitably be a trend, and it will gradually replace the rubber tube and become the only product used in industrial production, and only in this way can it better meet the needs of industrial manufacturers.

If the hardness of the silicone tube is not enough, how can we increase the hardness of the silicone tube and test the hardness of the silicone tube? First of all, because the main components of the silicone tube are vinyl and hydrogen-containing silicone oil, the vinyl content and hydrogen-containing silicone oil can be appropriately increased during production, and some silica and fineness can be added. At the same time, wollastonite powder can also be added. to increase the hardness, but it should be decided according to the needs of customers.

Secondly, there are three hardness testing methods for silicone tubes, namely: Shore hardness testing method, Shore hardness testing method and Rockwell hardness testing method.

Shore hardness test method: It is a dynamic force test, which is essentially different from other static force test methods. It is mainly suitable for determining the Shore hardness value of ferrous and non-ferrous metals. Shore hardness tester is easy to carry, especially suitable for medium and large workpieces in metallurgy and heavy machinery industries, such as large components, castings, forgings, crankshafts, rolls, oversized gears, machine tool guide rails and other workpieces.

Shore hardness test method: refers to the reading of the value measured by the Shore hardness tester, its unit is “degree”, and its description methods are divided into two types, A and C, which represent different hardness ranges. A hardness tester is used to test and obtain the data, and the foamed silicone tube is tested with a Shore C hardness tester and the data is obtained. Therefore, in general, for a rubber or plastic product, when testing, the tester can decide whether to use a Shore A durometer or a Shore C durometer to test according to whether the silicone tube is foamed.

Rockwell hardness test method: use a diamond cone with an apex angle of 120 degrees or a steel ball with a diameter of 1.59mm/3.18mm, press it into the surface of the tested material under a certain load, and obtain the hardness of the material from the depth of the indentation .

Finally, the above points are the methods to increase the hardness of silicone tubes and several methods to test the hardness of silicone tubes. Our factory can make design plans according to the needs of customers. Welcome to visit our website www.hiwowsport.com to leave a message.
