Kaneka B-51 Impact Modifier

Kaneka B-51 is an MBS core-shell impact modifier specially designed for transparent PVC, featuring stable impact resistance across a wide addition range. It maintains excellent room and low temperature impact performance at 10-16phr addition, while ensuring good transparency and color consistency with controllable whitening resistance, suitable for large-scale production of transparent PVC products sensitive to impact performance fluctuations.

Features Of Kaneka B-51 Impact Modifier

  1. MBS core-shell structure: Impact strength reaches 77.0kg·cm/cm at 0℃ with 16phr addition, outstanding low-temperature impact performance

  2. Good transparency: Light transmittance of 77.3% and haze of 4.6%, meeting basic appearance requirements of medium-high transparency PVC products

  3. Stable color difference: L value 81.9, b value 6.3, ensuring uniform product color and good batch consistency

  4. Moderate whitening resistance: L value 32.5, controllable whitening after bending, suitable for general bending scenarios

  5. Strong processing adaptability: Compatible with conventional PVC processes such as two-roll mixing (155℃×5min) and press molding (190℃×15min)

Typical Applications Of Kaneka B-51 Impact Modifier

  1. Impact modification of transparent PVC sheets and films, such as outdoor advertising films and thickened packaging films

  2. Transparent PVC injection molded products with medium-high impact requirements, such as children's toys and protective mask frames

  3. Toughening of transparent PVC pipes and profiles, such as transparent water supply pipes and equipment protection strips

  4. Transparent PVC products requiring low-temperature impact resistance, such as refrigeration equipment accessories and outdoor transparent covers

  5. Commercial transparent PVC products, such as supermarket display boxes and transparent turnover boxes
