Nucleating agent is a functional additive used in the processing and production of incomplete crystalline polyolefin such as polyethylene, polypropylene and other resin materials. A scientific and reasonable nucleating agent addition scheme can effectively improve the crystallization rate, crystal density, grain size and other crystallization behavior of the resin substrate, so that the product can obtain the expected transparency, rigidity, surface gloss, impact toughness, thermal deformation temperature and other excellent properties. Ji Haichuan can provide a series of products such as high-efficient stiffening nucleating agent, stiffening and transparency nucleating agent, thin-wall injection nucleating agent, and high transparency nucleating agent. Ji Haichuan has a series of nucleating agent production units, and the products have been widely used in the production of large domestic petrochemical plants and the processing and production of downstream olefin products.
