Styrene-Ethylene/Butylene block copolymer

This product is a linear, transparent block copolymer of the Styrene-Ethylene/Butylene-Styrene (SEBS) type. Its molecular structure is engineered to deliver a high-performance profile, characterized by the following key properties:

(1) Excellent Weathering and Heat Resistance: The saturated mid-block (ethylene/butylene) provides outstanding resistance to degradation from ozone, oxygen, and UV radiation, ensuring long-term stability in outdoor applications. It also maintains its properties at elevated temperatures, offering good heat resistance.

(2) High Mechanical Strength: The material exhibits remarkable tensile strength, tear resistance, and abrasion resistance, resulting in durable and long-lasting end-products.

(3) Good Compatibility with Plastics: It demonstrates excellent compatibility with a wide range of engineering thermoplastics, such as polypropylene (PP) and polystyrene (PS), facilitating easy blending for the creation of polymer alloys with enhanced characteristics.

(4) Clarity and Flexibility: The linear structure contributes to its transparency, while simultaneously providing high elasticity and excellent low-temperature flexibility.

Owing to its robust set of properties, this SEBS copolymer serves as a versatile modifier and base polymer across diverse industries. Its primary applications include:

(1) Plastic Modification: Used as an impact modifier and flexibilizer for rigid plastics, significantly improving toughness and soft-touch feel without sacrificing processability.

(2) Adhesives: Serves as a key component in formulating high-performance, permanent hot-melt adhesives (HMAs) and sealants, providing strong cohesion and UV-stable bonding.

(3) Compounding for Modification: Acts as a foundational material for producing customized thermoplastic elastomer (TPE) compounds tailored to specific hardness, color, and performance requirements.

(4) Toys and Consumer Goods: Ideal for manufacturing safe, durable, and soft-touch items such as toys, grips, and handles.

(5) Asphalt Modification: Enhances the flexibility, elasticity, and durability of asphalt binders used in roofing and paving applications.
