Kraton D-4274B Impact Modifier

Kraton™ D-4274B is a solid plastic elastomer of SBS type with high fluidity and medium-high hardness, featured by low specific gravity and good mechanical properties. It is mainly used for asphalt modification and shoemaking, also applicable to pipes, belts, auto parts and adhesives, and can be blended with resins/rubbers to adjust formulation viscosity, hardness and flexibility.

Features Of Kraton D-4274B Impact Modifier

  1. SBS block copolymer, solid plastic elastomer, medium-high hardness (Shore A 83)

  2. Ultra-high melt flow rate, excellent processability for various molding processes

  3. Low specific gravity, high tensile stress and good elongation, balanced mechanical properties

  4. Good compatibility with resins/rubbers, available as a performance modifier for blending systems

  5. Multi-scenario applicability, suitable for asphalt modification and light-weight industrial component manufacturing

Typical Applications Of Kraton D-4274B Impact Modifier

  1. Asphalt modification (road pavement, waterproof asphalt, improve processability and toughness)

  2. Shoemaking industry (light-weight sole, shoe upper elastic structural components)

  3. Plastic products (light-weight pipes, belts, sheets with high fluidity)

  4. Industrial components (medium-high hardness auto parts, medical devices, sporting goods)

  5. Adhesives & modifiers (resin/rubber blending systems, adjust formulation performance and reduce weight)
