Plastic processing aid-PPA Introduction

PPA's basic performance plastics processing aids-PPA can automatically accelerate blowing or calendering production speed, progressive equipment capacity, lower power consumption per unit of production and associated management costs. PPA can not change the blown film, calendering equipment original process conditions, the device can automatically improve the production capacity of 7-12%. Main motor without increasing the screw speed of the electrical energy but progressive case, the production capacity can be further improved to 10-15%.
Substantial reduction in the blown film process or calendering arising from crystallization point, including the human eye can not be directly observed tiny crystal point, therefore, can significantly reduce the fine print caused by the crystallization point of the "white spot."plastic flame retardant
Can significantly improve various blowing or calendering membrane surface smoothness, in particular in an optical microscope shows the microscopic smoothness, therefore, the transparency of the various types of membrane, the brightness of the printing ink, the uniformity of the fine dot printing , fine printing layering averaged progress.
Eliminate the die or device on the membrane surface of the drive components caused by longitudinal drag marks, including the human eye is difficult to see in normal light, high-intensity light source must be obvious to see the longitudinal drag marks. Can reduce the die temperature 10-15 ℃. Reduce die temperature, high performance PE materials for processing all types of great significance. As high performance PE materials melt viscosity, therefore, the process in the use of higher die temperature in order to obtain a higher degree of smoothness membrane. Die temperature is high, the body is calm qualitative blown bubble has a significant impact. Especially in the summer, due to the cooling air ring air temperature is higher, further qualitative impact foam body is calm. Therefore, it directly limits the speed of advancement of the blown film. PPA die temperature can be reduced 10-15%, therefore, can improve the performance of ordinary equipment for machining various Stable PE foam body material characterization, production speed of progress, providing a guarantee of process conditions.Metal soap
Progress various blown film, the thickness of the rolling membrane thickness uniformity and qualitative Stable. Membrane thickness uniformity and Stable qualitative, to ensure fine printing quality, to ensure the reliability and sealing strength plastic leveling of a resistance, to ensure multi-layer shrink film bubble volume expansion uniformity and fine printing pattern on a heat shrinkage After the isometric contraction, has important significance.
Plus a metallocene catalyst mLLDPE make the membrane, with a uniform sealing fastness, fastness of the sealing line to guarantee reliability and make the metallocene catalyst mLLDPE be added to the amount of physical control, the foam body Wen qualitative get progress. PPA can improve the mixing of different ingredients melt index melt plastics sex, mLLDPE melt viscosity at high shear rates than ordinary occasions, produced with a Ziegler catalyst PE is high, not only the foam body Wen qualitative decline, back pressure and to increase the extruder, the main motor torque progress. Is a new generation of high speed film blowing shear rate, high-speed multi-layer co-extrusion or calendering equipment characteristics. Some plastic bag factory for the sake of rapid advances in membrane sealing effect, tend to metallocene-catalyzed mLLDPE added amount raised high, not only the production costs increase, and PE melt process conditions deteriorate. PPA process after using the above types of questions can be significantly improved. Plastic processing aid-PPA
