Kaneka MR-501 Impact Modifier

Kaneka MR-501 is a silicone-acrylic composite toughener, mainly for impact modification and chemical resistance improvement of engineering plastics. It has excellent room and low temperature impact performance, good thermal stability, little effect on substrate tensile, flexural and other physical properties, suitable for PC and other engineering plastic modification needs.

Features Of Kaneka MR-501 Impact Modifier

  1. Silicone-acrylic composite system with excellent impact strength and thermal stability

  2. Good impact resistance at 23℃ room temperature and low temperatures of -30℃/-40℃

  3. Excellent retention of substrate tensile yield strength, flexural strength and modulus

  4. Good chemical resistance, resistant to contact with chemicals such as glacial acetic acid

  5. Good compatibility with PC substrate, no effect on the basic physical properties of the substrate after modification

Typical Applications Of Kaneka MR-501 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
