When we really want the additive to be evenly distributed throughout the polymer matrix, we would claim that we need to improve dispersion. Or we design the screw to have a distribution mixing element, but the material is easy to agglomerate and needs to be dispersed first before being distributed.

Plastic modification is a method of improving the quality of plastics by adding additives, fillers, etc. to alter their properties. Meanwhile, plastic modification is also the most effective way to reduce the cost of plastics. The elements of formula design in plastic modification mainly include material selection, compounding, dosage, and mixing method. The interaction between various elements can be either mutual assistance or mutual cancellation. Therefore, designing a high-performance, easy to process, and low-cost formula is not an easy task.

Nylon (PA) has a series of excellent properties such as high mechanical strength, chemical resistance, oil resistance, wear resistance, self-lubricating, and easy processing and molding, and has become one of the widely used thermoplastic engineering plastics both domestically and internationally.

Thermoplastic elastomers, abbreviated as TPE or TPR, are also referred to by many as SBS, a specific type of elastomer. But in reality, there is no unified name for thermoplastic elastomers both domestically and internationally, and most of the time they are represented by the English abbreviation TPE.

PVC needs to add additives in processing in order to produce various products that meet people's needs, such as soft, hard, transparent, good electrical insulation, foaming, etc. When selecting the variety and dosage of additives, it is necessary to comprehensively consider various factors, such as physical and chemical properties, flowability, and formability, in order to ultimately establish an ideal formula.

The main components of automobile lights are composed of reflectors, lenses, casings, light sources, electronic circuits, and installation accessories. With the development trend of lightweight automobiles, the proportion of plastics in automobiles is getting higher and higher.

Five common problems and solutions in plastic granulation 01 Black Dots 02 Broken Bar 03 Hollow 04 Material Overflow 05 Bridge Construction

Plastic extruder is a common plastic mechanical equipment. In the daily operation of the extruder, various faults are inevitable, which affect the normal production of the extruder. Below, we will analyze the faults of the extruder in detail.

Bridging occurs when materials interlock or bond together, forming an arch above the container outlet. There are many factors that cause the "bridging" phenomenon: particle size, shape, specific gravity, humidity, static electricity, the cohesive strength and internal friction of a single particle will all have an impact on the "bridging" phenomenon. When this happens, the arched structure holds the rest of the contents in the feeder in place, preventing the remaining material from being discharged.
