PBR 1220 Polybutadiene Rubber has a wide range of uses in the rubber industry, especially in the production of tires, footwear, belts, rubber hoses and other mechanical rubber products.
Characteristics of Polybutadiene Rubber/butadiene rubber PBR1220
Properties of Polybutadiene Rubber due to the molecular structure of cis-butadiene rubber is mainly cis-1,4-structure, the molecular arrangement is regular, so its elasticity is better than natural rubber. The glass transition temperature of Polybutadiene RubberTg = -105 ℃, so its low temperature physical properties are very good, cold resistance temperature below -55 ℃. The elasticity is one of the general-purpose rubber. Heat resistance is the same as natural rubber, both 120 ℃, but heat aging resistance is better than natural rubber. Tensile strength is lower than that of natural rubber and styrene butadiene rubber, so carbon black and other reinforcing agents must be added. Tear strength is also lower than natural rubber, wet slip resistance is not good, used in tire treads, shoe soles, easy to slip on wet roads. The abrasion resistance of smooth-butadiene rubber is excellent, the hysteresis loss is small, and the heat generation is low, which is very favorable to the products in the multiple deformation under the heat generation and deformation reduction.
Smooth butadiene rubber does not need to be plasticized before compounding. The compounds have good press-out properties and are suitable for injection molding, but have poor adhesion. The smooth-butadiene rubber is more sensitive to changes in processing temperature, when the roller temperature of the opener is above 60 ℃, the rubber is easy to peel off the roller, bringing some difficulties to the processing. Generally need to be used with natural rubber or styrene butadiene rubber, in order to improve the process performance.
Applications of PBR butadiene rubber
Polybutadiene Rubber is a synthetic rubber made by polymerizing butadiene monomer. It has high density, excellent physical properties and chemical stability, and is widely used in various fields. The following describes its main roles:
1. Automotive industry: Polybutadiene Rubber can be used in the manufacture of automobile tires, brake pads, seals and other components, with anti-wear, aging resistance, chemical corrosion resistance and other properties, which can extend the service life of the car.
2. Construction industry: it can be used in building waterproof materials, heat insulation materials, pipe seals and so on. Its excellent weather resistance, high temperature resistance, corrosion resistance and other properties, can effectively protect the safety and service life of the building structure.
3. Electronic industry: it can be used in electronic sealing, wire insulation materials, etc. It has the performance of high temperature resistance, waterproof, dustproof, etc., which can improve the reliability and service life of electronic equipment.
4. Medical industry: it can be used in medical devices, gloves, infusion sets, etc. It has excellent biocompatibility and hypoallergenicity, which can ensure the quality and safety of medical equipment.
