Kraton D-4274 Impact Modifier

Kraton™ D-4274 is a solid plastic elastomer of SBS type with high fluidity and medium-high hardness, featured by balanced 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-4274 Impact Modifier

  1. SBS block copolymer, solid plastic elastomer, medium-high hardness (Shore A 81)

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

  3. Balanced mechanical properties, high tensile stress and good elongation

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

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

Typical Applications Of Kraton D-4274 Impact Modifier

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

  2. Shoemaking industry (sole, shoe upper elastic structural components with medium-high hardness)

  3. Plastic products (pipes, belts, sheets with high fluidity and adjustable rigidity)

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

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