The nucleating agent is suitable for incompletely crystallized plastics such as polyethylene and polypropylene. By changing the crystallization behavior of the resin, the crystallization rate is increased, the crystal density is increased, and the grain size is refined, thereby shortening the molding cycle and improving the transparency of the product. New functional additives for physical and mechanical properties such as surface gloss, tensile strength, rigidity, heat distortion temperature, impact resistance, and creep resistance.
According to the difference in crystal morphology, it is generally classified into an α crystal nucleating agent and a β crystal nucleating agent. The α-crystalline nucleating agent mainly improves the transparency, surface gloss, rigidity, heat distortion temperature, etc. of the product, and is also known as a transparent agent, a penetration enhancer and a strengthening agent. Most of the types currently on the market belong to this category, including binary sorbitol (DBS) and its derivatives, aryl phosphate esters, substituted benzoates, etc., especially DBS nucleating transparent agents are the most common applications.
The β crystal nucleating agent is intended to obtain a polypropylene product with a high β crystal form content, and has the advantages of improving the impact resistance of the product without reducing or even increasing the heat distortion temperature of the product, and the contradiction between impact resistance and heat deformation resistance. All aspects are taken into consideration.
