Mitsui TAFMER DF840 Impact Modifier

Mitsui TAFMER™ DF840 is a high-transparency POE with excellent low temperature resistance and toughening effect, good fluidity and processability, suitable for plastic modification, automotive and packaging applications.

Features Of Mitsui TAFMER DF840 Impact Modifier

  1. Excellent optical properties with high transparency and low haze, meeting the appearance and use requirements of transparent products, suitable for food packaging, transparent accessories and other scenarios

  2. Brittleness temperature as low as -70°C, excellent impact resistance in low temperature environment, maintaining flexibility and elasticity in a wide temperature range without embrittlement failure

  3. Significant toughening effect on PP/PE polyolefin substrates, which can greatly improve the impact resistance and softness of substrates with strong modification adaptability

  4. Good melt fluidity with a melt flow index of 3.6g/10min, high-efficiency molding for injection molding, extrusion and blow molding with high processing efficiency

  5. Outstanding chemical corrosion resistance and weather resistance, able to resist the erosion of complex chemical media, UV and oxidation resistance for outdoor use with a long service life

Typical Applications Of Mitsui TAFMER DF840 Impact Modifier

  1. Automotive parts such as bumpers and instrument panels, with low temperature resistance and impact resistance, both flexibility and structural strength, improving the safety of vehicle use

  2. PP/PE polyolefin modification and toughening, as a special toughener, improving the brittleness of substrates and expanding the application scenarios of products such as pipes and containers

  3. Food packaging films/containers, high transparency and chemical resistance, complying with food contact safety standards, balancing display and use safety

  4. Cable sheaths and insulating materials for electronic and electrical appliances, with stable weather resistance and electrical performance, suitable for insulation protection needs of indoor and outdoor wiring

  5. Daily necessities such as toys and sports equipment, soft, high elastic and impact resistant, safe to use, improving the holding and use experience of products
