Polypropylene (PP) is a kind of high crystalline polymer, which has a slow crystallization speed during processing, which can easily form spherulites, thus affecting the transparency of products and impact strength of products.
The most effective way to modify PP is to add nucleating agent. Effective nucleating agent added crystallize ultra-micronization model.the, homogenizing, can greatly improve the transparency of PP and the surface glossiness, and impact strength, tensile strength, modulus and heat deformation temperature, suitable speed boost the quality of the products; At the same time, due to the accelerated crystallization speed, the molding cycle has been shortened and the efficiency of the enterprise has been greatly improved. Because the process of adding nucleating agent to the PP is simple, the addition quantity is small, the modification effect is obvious, so the use of nucleating agent is becoming more and more extensive.
Nucleating agent is used to add some crystal material in the polymer melt, melt heterogeneous nucleation at higher temperatures, increase the crystallization rate, at the same time make the polymer crystallization for easy demoulding curing at high temperature, so as to shorten the processing cycle, and improve product quality. Nucleating agent can further refine the crystallization structure of crystalline polypropylene, which is to increase crystallinity, reduce the diameter of spherulites and control certain morphology. Therefore, it can improve the rigidity of polypropylene, improve the transparency and luster, and reduce the molding temperature. Shorten the molding cycle and improve the PP performance.
Adding nucleating agent, polypropylene can be subtle spherulite structure, make the original all other nuclear a heterogeneous nucleation, increase the spherulite system within the number of crystal nucleus, multiply the number of crystallite, reduced Numbers of spherulite, thus can improve the optical performance of polypropylene, such as transparency or translucency. At the same time, the crystallization temperature must be lower than the melting point of PP, but it can not be too close to the glass transition temperature, so that the molecular chain has the necessary motility.
Nucleating agent for crystalline polyolefin resin modified additives, can make the plastic products has good processing performance and the use of performance, in order to give full play to the advantages of the nucleating agent, in recent years, the development direction is mainly nucleating agent distribution. There are significant synergistic effects of inorganic, organic or different nucleating agents, and multicomponent composite is an important trend in the development of modern polymer additives. The research field of compound nucleating agent is very active, such as the combination of sorbitol derivative and its subsidiary components to enhance the transparency of PP. Add sorbitol derivatives and other functional additives, such as organophosphorus antioxidants, fatty acids and esters, and obtain transparent PP with excellent comprehensive performance. Compound transparent agent Clarifexy 800 is processed by acid, ester, salt and other organic compounds. The development of compound nucleating agents is not limited to simple mixtures of several types of substances. It can also be designed for nucleating agent molecules to hold other functions. Such products are emerging. For the improvement of the sulfur and other substituents on the two benzyl rings of sorbitol derivatives, it is highly efficient, transparent and has the properties of anti-oxidative degradation.
