Kaneka MR-502 impact Modifier

Kaneka MR-502 is a silicone-acrylic composite solvent-resistant toughener designed for PC engineering plastic modification. It features outstanding low-temperature impact resistance, excellent thermal stability and chemical resistance, good retention of substrate tensile and flexural properties, and superior compatibility.

Features Of Kaneka MR-502 impact Modifier

  1. Silicone-acrylic composite system with triple excellent performance of impact resistance, thermal stability and chemical resistance

  2. Outstanding low-temperature impact resistance, significant improvement in impact strength at -30℃/-40℃ ultra-low temperature

  3. Good retention of PC substrate's tensile and flexural properties, no effect on the basic performance of the substrate

  4. Better chemical resistance than the same series, resistant to glacial acetic acid, sunscreen and other media

  5. Excellent compatibility with PC substrate, stable modification effect at 5phr addition, strong processing adaptability

Typical Applications Of Kaneka MR-502 impact Modifier

  1. Impact modification of PC, PBT, PC/ABS, PC/PBT and other engineering plastics as well as their alloys

  2. Production of chemical equipment accessories requiring high and low temperature impact resistance and hydrolysis resistance

  3. Toughening modification of flame-retardant PC/ABS alloy products

  4. Preparation of engineering plastic structural parts and precision accessories under high-temperature processing conditions

  5. Production of electronic and electrical parts, automotive engineering plastic parts used in outdoor and humid environments
