What are the main applications of silicone rubber products in the automotive industry?

Speaking of silicone products, it is estimated that the first thing that everyone thinks of should be mobile phone protective covers? In fact, silicone products have been used a lot in various fields, and they can be seen everywhere, as small as rice-sized silicone cold, mobile phone covers, speaker covers, Accessories for electronic products such as silicone watch wristbands, ranging from car seals, silicone tubes, sound insulation strips, etc.

Speaking of cars, many people have used cars and even own their own cars! Of course, there are many kinds of cars, let's talk about the common cars in our daily life. But do we understand automotive technology? What is its principle? What is its structure? What are the main components? I believe that many of us who use cars do not know this knowledge. Let's not talk about the development history and classification of automobiles. Today we mainly talk about the accessories used in automobiles: auto parts silicone rubber parts.

1. Multifunctional steering wheel button/window button: Many cars now have this function, and it is also our most commonly used/common thing. Many people may say that this is a plastic button. In fact, I tell you that the answer to plastic parts is wrong. Because it will not have elasticity, there are silicone buttons under the plastic parts. Silicone has corresponding elasticity, and the weight of the elasticity needs to be calculated. The elasticity of each car may be different, but the effect is the same, and the buttons are used To operate a certain function on the car.

2. Oil seal/silicone seal ring: There are many applications of seals/rings in cars. The common one is that our cars need to be maintained after driving for a period of time or kilometers. Do maintenance personnel need to lift the car up and turn on the fuel tank to remove the old oil Let it out? Why doesn't the engine oil leak out, because there is a silicone waterproof seal inside, of course, there are also silicone rubber seals/rings in other places, such as glass water tanks, booster fuel tanks, steering wheels, engines and other places. It's just that we rarely see them. Although they are in different parts, their functions are basically the same, and they are all used to prevent liquid leakage.

3. Car sealant: Have you noticed? The circle of black (and other colors) elastic things that we can see when we open the car door is the sealing strip. The door is the most common position we see, and there are other positions, such as car windows, seats, sunroofs, and backups. Boxes, etc. Their functions are generally sound insulation, noise reduction, waterproof, dustproof, shock absorption, etc. The automotive sealing strip has the advantages of good elasticity, resistance to compression deformation, and anti-aging.

4. Silicone tube: gasoline/diesel cars have oil lines, and glass water has water pipes. A silicone tube is needed to transfer oil and water. Different types of cars use different amounts, but they have the same thing. The silicone tube is not a big piece for the entire car, but it is also very important. If it is damaged (common Damage is the car's chassis being bumped), repair/replacement is still more troublesome, so we have to cherish our car.

5. Car rubber cushions: "Wow, this car is so comfortable to sit on", many people will feel this way. When the car passes through the potholes, we will not feel too bumpy. In addition to the design of the car itself, it also has a lot to do with shock absorption. Some cars have a harder shock absorption design, and the ride may feel more bumpy. On the contrary, if you use a softer design, the ride feels less bumpy. They have their own advantages and disadvantages, such as harder shock absorption. , It can carry heavier cargo, the contrast with it is the difference in turbulence, but their shock absorbers are all rubber parts, but the rubber hardness requirements are different. Their function is the same, they are all used to absorb the shock. If there is no rubber shock absorber, the effect will be the same as some old cars (steel plate type) before, which is more bumpy! The shock absorbers introduced above are mainly used in the suspension On the top, some seats have cushions on the nose. Interested friends can go to learn more, its role is still very good, it will not be so uncomfortable for people to ride.

6. Engine intake pipe: The engine is the "brain" of the car. We often say that the three major parts of the car, of which the most important one is the engine. It can be seen that the engine is of greater significance to the car. For those of us who use cars, we may not know much about the engine intake pipe (people who repair cars and produce cars should know more). We can imagine that the engine is also a machine, and it needs supplementary energy to operate. Just like people need to eat. Of course, the engine does not need to eat, but it needs to "suction", this function needs to use the intake pipe. Our common car engines have two forms: naturally aspirated and turbocharged. The engine intake pipe is generally made of rubber, and if it is subdivided, it is generally EPDM/NBR/KM. There are also other subdivided materials, which can be customized according to design requirements. It is characterized by good sealing performance, high and low temperature resistance (turbocharged engines usually have a higher working temperature than naturally aspirated ones), anti-aging and so on.

7. Handlebar sheath: People who have driven a car should know this better, that is, our gearbar (manually geared car) has a sheath on the top, and an iron rod and bearing below. If you don't have this sheath, look It is not beautiful. The main function of the barrier sheath is to be beautiful and dustproof.

8. Harness sheath: There are now a lot of general entertainment equipment and electronic products in automobiles, such as automatic parking, car navigation, driving recorder, etc., they all need wires to connect the battery to ensure that they can be used normally after powering on. Outdoors (individually there are indoor parking lots), the wires are easily damaged by the wind and sun every day, so we have this wire harness protective cover to slow down the aging time of the wire and protect the wire harness (for example, if the bottom is knocked, the wire harness sheath Broken, the wire is not broken).

9. Rubber tires: Everyone should know about tires. There are many well-known companies in the world, and there are also many companies that make tires in China. However, no matter which country the tires are, they are generally made of rubber. Everyone knows its usefulness. I won't introduce too much.

10. Car phone silicone pad: This may be a bit unfamiliar to many people, because each car is different, its location is different, and its functions are also different. The general function is to prevent slippage of items. Now a new car silicone pad has been released, which has the function of wireless charging. Technology is really changing life.

11. Wiper: Maybe your wiper won't work for 1 month, others can use it for 6 months. The quality of the wiper has a big relationship with the material! However, they are generally made of silicone (individually with rubber, with a small proportion). Regardless of whether it is good or bad, the material is silicone or rubber. The common point is that it can help drivers see the road clearly when it rains.

12. Automobile rubber parts/silicone parts: Let me talk about it roughly. Silicone rubber products are also used in the part of the car. For example, there are more or less silicone rubber in the brake system, chassis, rearview mirror, engine periphery, etc. The product may not mean much to the entire car, but it is certain that it has the benefits and significance of its existence.

    
    

Conclusion: Silicone rubber products have gradually become popular in our daily lives, and I believe that it will have more uses for us to discover in the future. Silicone rubber parts do not account for much in the entire car, but it does have its value. We are a professional manufacturer of silicone products in China. You are welcome to contact us at any time to customize all kinds of silicone products you need.
