PVC particles are PVC epoxy resin powder plus various modifiers such as halogen-free flame retardants, tackifiers, lubricants, food grade, fillers, tear resistance modifiers, additives, etc. According to the modification Produced and processed. According to the composition of the tackifier, it can be divided into rigid PVC particles and soft plastic PVC particles. Rigid PVC particles have excellent flame-retardant properties because the tackifier composition is below 10%, and 0.5-thick flame-retardant PVC materials can be modified.

The customers I met, most of the products are thicker than 1.3 mm, because of the thin products, its applicability is very low. Rigid PVC particles can guarantee a 1.2 mm thick V-0 flame retardant level. It is no problem. If 0.5 thick flame retardant PVC is to be guaranteed, it is likely that a part of the synergistic flame retardant needs to be added to the rigid PVC material. Agent and brominated flame retardant. Generally speaking, 0.5-thick flame-retardant PVC products mostly appear in film products and injection molded products, and the sales market of PVC film is also relatively large.

PVC is a multi-component plastic that can be molded and processed in a variety of ways, with a wide variety of products and a wide range of uses. Through the best combination of resin and additives to meet the molding processing and use conditions, the ideal product can be obtained. To do this, it is necessary to understand the type of PVC, processing characteristics and the relationship between molding and products. For example, suspension PVC resin is often used for extrusion, injection molding, calendering, pressing, and blow molding; emulsion PVC resin is often used for molding, dipping, slush molding, etc.

What kind of plastic is pvc? Processing characteristics of polyvinyl ethylene:

1. The thermal stability of the molding process, PVC will decompose at 140°C, which brings great difficulties to the molding process. Therefore, the stabilizer must be heated to increase the decomposition temperature during the molding process. Generally, the decomposition temperature after heating the stabilizer can reach 200°C. Even so, it is not suitable to use too high temperature in the molding process, and staying at high temperature for too long will cause PVC The phenomenon of thermal decomposition.

2. What kind of plastic is pvc? In order to reduce the viscosity of the PVC melt, it should not just increase the temperature to cause it to decompose, but also increase the pressure and increase the shear rate to improve its fluidity.
