Mitsui TAFMER DF640 Impact Modifier_copy20260203110942

Mitsui TAFMER™ DF640 is a low-density high-transparency POE with high fluidity, excellent low temperature resistance and compatibility, easy to process, suitable for packaging, automotive and wire cable applications.

Features Of Mitsui TAFMER DF640 Impact Modifier

  1. Low density and high transparency with excellent optical properties, the products are lightweight and have good light transmittance, balancing material cost control and appearance display requirements

  2. Brittleness temperature below -70°C, maintaining flexibility and impact resistance in a wide temperature range, no embrittlement at low temperature, stable molecular structure with excellent weather and aging resistance

  3. Excellent melt fluidity with a higher melt flow index than conventional models of the same series, high efficiency in injection molding and extrusion, suitable for high-speed processing production lines

  4. Excellent compatibility with polyolefins such as PP and PE, which can improve the flexibility and impact resistance of the substrate after blending, and easy to realize large-scale modified production

  5. Support crosslinking modification, the heat resistance, mechanical properties and chemical resistance are significantly improved after crosslinking, which can expand high-end industrial application scenarios

Typical Applications Of Mitsui TAFMER DF640 Impact Modifier

  1. Automotive lightweight exterior parts such as bumpers and fenders, low density and impact resistance, balancing the needs of vehicle weight reduction and impact protection

  2. High-transparency packaging films such as stretch wrap film and food cling film, high transparency and puncture resistance, suitable for high-speed film making process

  3. Wire and cable insulation layer, stable electrical performance and weather resistance, suitable for wiring insulation in outdoor and low temperature environments

  4. Transparent soft daily necessities such as children's toys and soft storage containers, soft and safe, with both light transmittance and deformation resistance

  5. Shoe midsole/soft parts, flexible and good resilience, improving the wearing comfort and walking cushioning effect of shoes
