Automobile and rubber products used in high-performance materials to the transition

1. Tire

With the improvement of conditions for the use of tires, winter tires, ultra-low rolling resistance tires, tire safety, and tire-tread surface twins will be further applied to energy-saving, high-speed, stable, lightweight, durable direction of evolution . In order to energy, rubber material should have the characteristics of the rolling resistance of the small, high-rebound, but the tires are high-speed stability requirements of wear-resistant material with high creep, that is, low-bounce. Recently developed at the end of the modified S-SBR on the material to meet the above-mentioned contradictory performance requirements. In general, the tire tread can use the E-SBR, S-SBR, NR, IR, such as rubber, carcass can be used NR, BR, IR, such as plastic. In addition, energy-saving and safety of the silicone rubber with a better S-SBR with a tire material will be applied.

2. Automobile seal doors and windows

Seal products account for vehicle weight of rubber -28% 25% (except tires). Recently, with ozone-resistant, weather-resistant properties of the aging of the EPDM rubber is widely used in car doors and windows closed, and will gradually replace traditional plastic CR and NR. Each vehicle can use a variety of 10-15 meters long seal. In order to further reduce costs and aesthetic appearance, foreign manufacturers have been using TPE materials to make car doors and windows be sealed.

3. Seal

Oil seal material to make more use of nitrile, hydrogenated acrylonitrile-butadiene, acrylic rubber materials such as oil. Due to the improvement of heat resistance, the special rubber (such as fluorine rubber) and the amount of species growing demand.

4. Automotive air hose

According to the assembly of its use in different locations and have different requirements, such as oil, bending resistance, as well as the shock absorption properties of heat resistance and so on, so the types of materials are also more, such as CR, NBR / PVC, EPDM, ECO, CSM , ACM, such as rubber. Recently, in order to lower costs and lighter, and TPO started TPEE, but also in the shape of the design of their products take full account of the shock absorption properties.

5. Water System SAM

Including the radiator hose, heater hose, and so on, most of the use of SBR, EPDM rubber. With the engine room temperature increases, the use of peroxide curing the beginning of EPDM rubber.

6. Brake hose

The general use of SBR rubber, in order to satisfy the recent heat resistance and anti-aging requirements and began to promote the use of EPDM or EPDM / IIR rubber.

7. Lubrication system SAM

In the use of lubricants, as more and more high-temperature environment, and other antioxidant additives are also increasing the amount. Although the NBR rubber has excellent oil resistance, but adding antioxidants will happen after hardened, so now start using all kinds of resistance with a good performance ACM rubber additives, as well as heat resistance and oil resistance rubber FKM's.

8. Power steering hose

Under normal circumstances, the power steering with endothelial NBR, the jacket with CR, but with changes in temperature and additives, started HNBR / CSM hose material.

9. Fuel pipe

The general use of NBR rubber, with the injection of electronic devices as well as the application of oxygen-fuel element of the increase in the use of the beginning of FKM, HNBR, CSM rubber, and so on. , The skin can also use different materials, the jacket can be used EPDM, TPO, and other materials.

10. With air-conditioning hose

With the media have air-conditioning CFC-12 into HFC-134a, and compressor lubricants from mineral oil to PAG lubricants, air-conditioning hose from the NBR rubber into PA / EPDM blends modified material. In order to PAG-resistant lubricants, hose made 4 layer composite pipe from the inside out are the PA / IIR / polyester / EPDM, which IIR water permeability of good material.

11. Damping products

Block buffer, pad, shock absorption, and other plastic products for the general NR and SBR materials. With the heat-resistant requirements of the increased use of part of the product EPDM, but the dynamic properties of EPDM and durability than NR, therefore, still mainly NR.

In a better buffer block material has not been found, the beginning of the current use of the enclosed oil shock absorption block, essentially to meet the requirements of Hyundai Motor's shock absorption.

12. Dust

The most important thing is a good request weatherability materials (in natural materials can be used exactly how long it will be collectively referred to as its weatherability), and based on the use of different parts of the resistance has to be twists and turns, oil, such as wear-resistant properties. Velocity joint general use CR weathering material, but with the heat resistance required to raise, Europe and the United States and Japan, part of the car started TPEE.

TPEE materials to meet the weather, oil, heat, light at the same time.

13. Tape

V-belts, gear-type material with the requirements of high strength, modulus, good thermal stability. CR is a traditional rubber material, but because of their heat tolerance limit will be 110 ℃, therefore, have recently begun to use heat-resistant, durable rubber HNBR replaced.

HNBR of the heat-resistant than the CR high 40 ℃, life expectancy longer than the CR rubber 2 times.

In short, with the continued development of the automotive industry, although domestic vehicle with the development of the rubber products industry is also very uneven, both production technology, equipment, technology or product quality is still not fully carried out against the international giants, such as rice accompanied by Its forests, Bridgestone, Goodyear, and so good of the world's major automotive rubber products manufacturer to enter the domestic car production and the rubber products industry, technology and management level of competition is bound to be continued to enhance not only meet the domestic car Matching demand, while the international market.
