Material Characteristics
The products are a range of non-oil extended grade thermoplastic elastomers (TPEs). They are block copolymers based on Styrene and Ethylene/Butylene, with two primary molecular architectures: linear and radial structures. The bound Styrene content varies across different grades, typically within the range of approximately 29% to 35.5% by weight. This specific chemical composition grants the materials excellent thermo-mechanical properties. Key characteristics include high elasticity, superior tensile strength, good abrasion resistance, and outstanding low-temperature flexibility. Furthermore, these polymers exhibit strong resistance to oxidation and weathering, making them suitable for demanding environments.
Material Application
These versatile SBS copolymers are widely used as high-performance modifiers and key components in various industries. Their primary applications include:
(1) Asphalt Modification
Enhancing the flexibility, elasticity, and durability of asphalt pavements and roofing materials, especially under extreme temperature variations.
(2) Plastic Modifier Compounding
Improving the impact resistance, flexibility, and soft-touch feel of rigid plastics like polypropylene (PP) and polystyrene (PS) without significantly compromising their strength.
(3) Adhesives, Sealants, and Coatings
Serving as a base polymer for formulating high-quality hot-melt adhesives (HMAs), sealants, and coatings, providing strong bonding strength and flexibility.
(4) Compounding for General Modification
Used as the primary raw material in compounding to produce customized TPE compounds for specific customer requirements.
(5) Consumer Goods
Suitable for applications such as toys, grips, and soft-touch components due to their safety and performance properties.
