Melt flow rate is referred to as melting finger in this paper.Finger height is the reaction of the polymer in the high temperature processing molten state of the flow performance of the melt, the higher the melt, the better the flow.According to international standards, the melt index is measured by the melt weight passing through the capillary in 10 minutes at constant load and constant temperature.In the production process, under the same technological conditions, the higher the melting finger of raw materials, the more material through the mold per unit time, the thicker the thickness of products.
P1-1 is a modifier that can greatly improve the fluidity of PP. It is a kind of peroxides. Under high temperature conditions, P1-1 produces free radicals that attack the main chain of PP, establish a new active site to break the molecular chain of PP, and reduce the average molecular weight of PP, so as to significantly improve the fluidity of PP.To improve the process difficulty of spinning in drawing and melt-blown processing, when applied to the melt-blown field, it is only necessary to add about 1.5%-2% P1-1 to increase the melting finger of 30-40 PP raw material to about 1500.Download
Usage: When using P1-1, it must be mixed evenly with the raw material. The best mixing effect is that P1-1 powder is uniformly adhered to the raw material particles.For example, 1000kg of raw materials need to be processed, and the additive amount is 1.5%.That is, 15kg of P1-1 is weighed, and 1000kg of raw materials are fully mixed with P1-1 by horizontal mixer or other types of mixing equipment, and then the raw materials mixed with P1-1 are transported to the processing equipment for processing and production.
