Kraton D-4272 Impact Modifier

Kraton™ D-4272 is a solid plastic elastomer of SBS type with high hardness and good fluidity. It is mainly used for asphalt modification and shoemaking, also applicable to pipes, belts, auto parts, medical devices and adhesives. It can be blended with resins/rubbers to modify and adjust the viscosity, hardness and flex resistance of formulations.

Features Of Kraton D-4272 Impact Modifier

  1. SBS block copolymer, solid plastic elastomer, high hardness (Shore A 90)

  2. High melt flow rate, excellent processability for various molding processes

  3. High tensile stress, moderate elongation, good mechanical strength and structural stability

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

  5. Multi-scenario applicability, suitable for high-hardness demand asphalt modification and industrial component manufacturing

Typical Applications Of Kraton D-4272 Impact Modifier

  1. Asphalt modification (high-performance road pavement, waterproof asphalt, improve rigidity and toughness)

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

  3. Plastic products (high-rigidity pipes, belts, sheets with good processability)

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

  5. Adhesives & modifiers (high-hardness adhesive formulations, resin/rubber rigid modification)
