Nucleating Agent also named Clarfying agent is a modifier that promotes polymer crystallization and improves its grain structure. The nucleating agent acts as the carrier of the resin and forms the plastic film to ensure increased density, improved tensile strength, increased stiffness and stiffness, and can greatly change the fluidity. It is especially suitable for the manufacture of precision plastic products and reduces wear in the process. Improve the quality and smoothness of the outer film on the surface of the product. Nucleating agents can greatly improve impact resistance, toughness, stability and reduce system shrinkage and expansion. The nucleating agent has a strong anti-heat and anti-freeze ability, and at the same time improves the wear resistance and corrosion resistance of the system.
