MK-302 ACR Impact Modifier (Acrylic Impact Modifier)

Raw Materials & Manufacturing Process

MK-302 is produced from butyl acrylate and methyl methacrylate monomers using seed emulsion polymerization to form a core-shell structured polymer. It is then processed through coagulation, demulsification, washing, dehydration, fluidized bed drying, and ultra-fine pulverization.

The product features uniform molecular weight distribution, with outstanding weather resistance and impact performance.

Product Functions & Key Advantages

• Superior Impact Efficiency:
  Significantly better low-temperature impact strength than CPE, providing excellent resistance to dropping and impact
• Plasticization Promotion & Reinforcement:
  Enhances uniform plasticization of PVC, improves melt strength and ductility, and reduces product breakage
• Improved Appearance:
  Enhances surface gloss and dimensional stability, resulting in smoother and more precise products
• Outstanding Weather Resistance:
  Long-term outdoor use without yellowing, chalking, or cracking
• Excellent Cost Performance:
  Lower dosage required, delivering better overall performance than conventional impact modifiers
