III. Product Characteristics:
1. Superior Elasticity and Flexibility
SBS 792 features a unique biphasic structure. The polybutadiene segments impart rubber-like high elasticity, enabling rapid deformation recovery at room temperature with excellent rebound properties. The polystyrene segments act as physical crosslinking points, providing rigid support that balances elasticity with dimensional stability. During repeated bending and stretching, it resists permanent deformation, making it ideal for applications demanding high elasticity.
2. Outstanding High and Low Temperature Resistance
At low temperatures (-40°C), SBS 792 maintains excellent flexibility and elasticity without brittle fracture, ensuring stable performance in cold regions. At high temperatures (80°C), its elevated melting point prevents softening and deformation, delivering superior dimensional stability to meet diverse climatic demands.
3. Superior Aging and Weather Resistance
Its unique molecular structure provides strong resistance to UV radiation, ozone, and oxidation. When exposed to outdoor environments over extended periods, it resists aging, cracking, and discoloration, effectively extending product lifespan and reducing maintenance and replacement costs associated with degradation.
4. Exceptional Processability
SBS 792 exhibits excellent flow properties, enabling processing via extrusion, injection molding, calendering, and other methods. It demonstrates good compatibility with plastics like polypropylene (PP) and polyethylene (PE), as well as fillers such as calcium carbonate and talc. This facilitates modification during production, allowing formulation adjustments for diverse high-performance products tailored to specific application requirements.
5. Outstanding Bonding Properties
It exhibits strong adhesion to multiple substrates (e.g., metal, plastic, wood). It can serve as a modifier to enhance interfacial bonding strength between materials and is suitable for producing high-adhesion products like hot-melt adhesives and pressure-sensitive adhesives.
IV. Product Applications:
Adhesive Industry: This is a specialized grade for adhesives, primarily used in the hot-melt adhesive sector. It can be employed to produce various types of adhesives, particularly hot-melt pressure-sensitive, pressure-sensitive, and solvent-based adhesives. It features strong bonding strength, non-toxicity, and no environmental pollution.
Plastic Modification: Can be blended with plastics such as polyethylene, polypropylene, and polystyrene to enhance their physical properties, improve impact resistance, and broaden their application scope.
Asphalt Modification: Adding 3%-15% SBS791 to asphalt improves low-temperature flexibility and high-temperature flow resistance, effectively extending the service life of roads and roofing membranes. Modified asphalt overcomes the drawbacks of brittleness in winter and softness in summer, making it suitable for road paving and repair, as well as producing high-quality waterproof and thermal insulation materials.
Footwear Industry: Suitable for producing leather shoes, sneakers, and children's footwear across various grades. Offers advantages including comfort, slip resistance, breathability, and easy dyeing. Features a simplified production process with recyclable scrap materials.
Other Applications: It can also be used to manufacture various elastic rubber products, such as hoses, belts, rings, indoor flooring materials, sports equipment, automotive mudguards and floor mats, children's toys, and mechanical parts. It is also applicable in the coatings and inks sector. When added, the resulting coatings and inks exhibit enhanced properties in certain aspects, such as surface elasticity of the coating film, low-temperature resistance of the coating film, better adhesion to rubber substrates, and the ability to produce low-temperature resistant transparent gloss varnishes.
V. Product Packaging:
20 kg per bag. Store in a cool, dry, well-ventilated warehouse, avoiding direct sunlight and rain exposure. Keep away from heat sources and open flames. Storage temperature should be maintained between 5–35°C. Shelf life is 12 months. Under specified storage conditions, product performance remains stable and reliable.
