High styrene powder rubber

High styrene powder rubber is copolymerized with styrene monomer and butadiene monomer by lotion polymerization process. High styrene rubber has lower unsaturation than ordinary styrene butadiene rubber, stronger antioxidant capacity, better aging resistance, high hardness, strong wear resistance, and excellent reinforcement effect; Its prominent feature is its reinforcing effect on elastomers, which can improve the rigidity, hardness, and wear resistance of natural rubber.

Performance

This product has a styrene content of 65% to 75%. This product is non-toxic, odorless, flammable, with low impurity content and stable performance. Due to the high content of styrene monomer in long-chain molecules, the product is endowed with better aging resistance, higher hardness and rigidity, greater mechanical strength and tear strength. Its good mechanical properties, elasticity, and excellent compatibility make this product widely used. When mixing high styrene powder rubber, the roller temperature needs to be preheated to 80 ℃ to 100 ℃.

Advantage

1. Aging resistance: The high styrene content in the molecular chain of high styrene powder endows it with better aging resistance

2. High temperature deformation resistance: Its thermal deformation temperature is 70-90 degrees Celsius, and this product also has certain toughness and elasticity at high temperatures, making it suitable for use in higher temperature environments.

3. Material strength: higher hardness and rigidity, greater mechanical strength and tear strength.

4. Environmental safety: non-toxic, odorless, odorless, pollution-free, in compliance with environmental requirements.

Main purpose

1. Tires and rubber accessories: added to natural rubber or synthetic rubber to improve the hardness, wear resistance, and tear strength of the tread rubber, suitable for heavy-duty tires, off-road tires, etc.

2. Industrial rubber products: used for manufacturing rubber rollers, seals, shock absorbers, etc., to enhance the rigidity and wear resistance of products.

3. Sole material: Composite with natural rubber or polyurethane to enhance the hardness, slip resistance, and aging resistance of the sole.

4. Plastic modification field: It can be used for toughening modification of plastics such as ABS, PS, AS, etc. to enhance their toughness and impact resistance, while maintaining their elasticity and processability at high temperatures.

5. In the field of coatings and adhesives: used for bonding rubber and metal, rubber and fabric to enhance bonding strength and temperature resistance. Improve the adhesion, wear resistance, and chemical corrosion resistance of coatings.

Usage

High styrene powder rubber can be blended with butadiene rubber, natural rubber, and styrene butadiene rubber in any proportion, except for standalone use. It is used for high-strength imitation leather shoe soles and foamed microporous shoe soles, high-end bicycle light colored outer tires, various rubber rollers, rubber plates, and electrical insulation materials. Blending with nitrile rubber and chloroprene rubber to manufacture high hardness oil resistant rubber products, such as textile rubber accessories, oil resistant rubber plates, oil resistant rubber rollers, etc. Used for toughening modification of ABS, AS plastics, etc; Toughening modification of transparent PS sheet. Its dosage is generally 10% to 50%.

Packaging, transport and Storage

It is recommended to store indoors in a cool and ventilated place, with a storage temperature below 45 ℃. This product is a non-toxic, non corrosive powder and belongs to non hazardous chemicals. It should be handled as a non hazardous chemical during transportation and should be strictly protected from exposure to sunlight and rain. The shelf life is 1 year. After 1 year of performance testing, if there is no change, it can still be used.
