2.What are the application problems of NC white foaming agent series?
Compared with the foaming agent AC, the NC series can make the small nuclei evenly distributed (nucleation effect) and the surface is smooth (easy to apply paint), avoiding the problem of not coloring.NC series can be used in injection molding and extrusion systems, the recommended dose of 0. 2~1. 5% mass fraction, the actual use of processing temperature in the process of 180-220°C suitable. NC series are widely used as nucleating agent for thermoplastics. For example, the foaming of polyolefin, Pseva. PVC and other materials uses the direct injection of olefin, pentane, benzene, nitrogen and C02 gas foaming. Because in the high pressure process will promote the nucleus and form a good nuclear structure. But also use in the injection extrusion of many different thermoplastics, such as PVC, PS, ABS, PE, PP and modified PP0 processing.
