Polyvinyl chloride (PVC) is a polymer formed by the polymerization of vinyl chloride monomer (VCM) in the presence of initiators such as peroxides and azo compounds or under the action of light or heat according to the free radical polymerization mechanism. Vinyl chloride homopolymers and vinyl chloride copolymers are collectively referred to as vinyl chloride resins.

In the PVC (polyvinyl chloride) processing technology, mixing technology plays a vital role as the first process in the production of PVC products. However, many companies often do not pay enough attention to the mixing process, which leads to misunderstandings among workers about mixing technology, thinking that it is enough to just mix the materials evenly. This article will introduce the role, principle and process of PVC mixing in detail to help readers fully understand PVC mixing technology.

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.

Plastic extrusion is a process in which plastic materials are transformed from solid to liquid and remade into finished products. First, the plastic particles are gravity fed from the hopper into the sheathed screw. When the screw rotates around its axis, it conveys, melts and pressurizes the plasti

There are many different pvc compounds to choose from. A special composite should be able to provide a plastic compound to meet the needs of your product, whether it is ready-made or specially designed for you. A compositor should have technical experts who can work with you to provide solutions and

PVC compounds are used for many things, it can be said that it is a thermoplastic, that is, when heated, it can change shape. This means you can turn it into all kinds of exciting things. It can be rigid or flexible, depending on its thickness and composition. Remember the plastic wrap you used to c

Plastic extrusion is to extrude molten plastic through a mold into a shape with a fixed cross-section. It is an effective method to produce a variety of shapes and is essential in industrial and household product applications. Since plastics are melted from a solid form and then liquefied, only ther

conical twin screw extruder for pvc compound and pelletizing

Counter-rotating twin-screw extruders are another type of twin-screw extruders, which include two kinds of parallel and conical extruders.
