    We all know that the main raw material of the tire is rubber, but only rubber is not enough. It is also necessary to add various additives to make the tire have good elasticity, low rolling resistance, low fuel consumption, low heat generation and wear resistance. The performance of puncture resistance, large carrying capacity and comfortable ride depends largely on the opening and selection of the raw materials of the tire.
    Introduce the following new tire materials and additives that have emerged in recent years.
    Oil-filled natural rubber (OENR): not only can reduce the rolling resistance to a large extent, but also can achieve high ice grip performance.
    Polybutadiene rubber: Polybutadiene rubber and solution-polymerized styrene-butadiene rubber can be used together as a fuel-efficient tire tread rubber. The tire with this tread rubber has the best balance of grip and wear. Lower rolling resistance saves 5% of fuel.

    Foamed rubber: The so-called foamed rubber refers to a rubber having many micro-independent bubbles. When the foaming rate is 20% to 30%, the friction coefficient on ice can be increased by 3 to 4 times. In this way, the tire braking distance can be shortened by 10% to 15% by increasing the friction coefficient on ice. The anti-slip tires with foamed rubber have less friction on ice than the studded tires, but their friction is very close.

    Polyurethane elastomer: It has the advantages of high wear resistance, coloring, high cut resistance, excellent oil resistance and chemical resistance, and it has no toxic effect on the human body, and it can be completely biodegraded without adding carbon black and aromatic oil. It is an ideal material for making tire treads.

    Silica: Silica, also known as hydrated silica, activated silica and precipitated silica, can achieve high wet traction and wet road brakes through the use of special polymers and silica/silane systems. Performance and reduced fuel consumption by 5% by reducing rolling resistance.

    BoTred (new starch-based filler): BoTred is a new filler based on starch. Corn starch derivatives are first extracted from corn, converted into microdroplets and converted into biopolymer fillers. BloTred is a spherical particle that minimizes mechanical energy and reduces rolling resistance.

    Short fiber: the addition of short fibers can increase the rigidity of the tire, so that the amount of sinking is significantly reduced when the tire is subjected to the same load during driving, that is, the deformation of the tire is reduced, and the rolling resistance is also reduced; the short fiber is used for the tire tread In time, not only the rigidity of the tread can be increased, but also the friction coefficient of the tread can be lowered, the rolling resistance coefficient is lowered, and the rolling resistance is also lowered accordingly. When short fibers are applied to tire treads and other parts, the properties of the rubber can be changed by the modulus and anisotropy of the short fibers to reduce the noise during the running of the tires, and also to improve the durability of the tires.

    Adding silicon formula: The core is to add silicon material to the tread rubber. The silicon-containing tires have less grip energy and less energy loss, which reduces rolling resistance and wear and is better than ordinary tires. The fuel-saving effect and extend the life of the tire as much as possible.
