      Modified plasticIntroduction
      Modified plastics refer to plastic products on the basis of general-purpose plastics and engineering plastics that are processed and modified by methods such as filling, blending, and reinforcement to improve flame retardancy, strength, impact resistance, and toughness. Modified plastic parts can not only achieve the strength properties of some steels, but also have a series of advantages such as light weight, rich colors, and easy forming, achieving the effect of replacing steel with plastic.
