In the quality indicators of raw materials, we often encounter some terms. Accurately understanding their meanings will help us better grasp the performance of raw materials. Here are some commonly used terms.

To improve the film's sliding properties, a sliding additive is introduced during its production (usually the active substances are oleamide and erucamide). After film extrusion, the additive migrates to the surface and creates a sliding layer on it, due to which the friction coefficient is significantly reduced and the film's sliding properties are improved.

Have you solved these problems encountered in the production process of TPE extrusion materials? 1. Rough surface of molded product 2. Scaling 3. Unstable extrusion volume 4. Deformation 5. Stripes

The plastic granulator is a kind of equipment commonly used to produce plastic granules. The temperature regulation of each area is very important for product quality and production efficiency. The following will introduce in detail the temperature regulation method of each area of the plastic granulator.

CaCO3 powder, also known as calcium carbonate powder, is often added to plastic pellets for the following reasons:1. Reduce costs 2. Improve mechanical properties 3. Density Adjustment 4. Improved processing properties 5. Environmental benefits 6. Improve the heat resistance of plastic products 7. Improve the light diffusion of plastics 8. It can make the product have some special properties

The structure of a twin-screw extruder is very similar to that of a single-screw extruder, but its working principle is very different. In a single-screw extruder, material transportation relies on the friction and viscous resistance of the material, so the residence time distribution is wider. In contrast, the material conveying of the twin-screw extruder relies on the positive displacement of the screw, so the residence time distribution is narrower. The raw materials of the twin-screw extruder are fed through the feed port by a metering feeder. Some additives (such as glass fiber) need to be added through the feed port in the middle of the barrel and transported to the die head by the screw. During this process, the movement of the material varies depending on the screw meshing method and the direction of rotation. This article will introduce the specific differences in their working principles from this perspective.

Six kinds of recycled plastic process 1.Process flow of recycled low-density polyethylene (LDPE) 2.Recycled Polypropylene (PP) Process 3.Recycled polyethylene terephthalate (PET) process flow 4.ABS plastic process flow 5.Recycled Polycarbonate (PC) Process 6.Recycled polyvinyl chloride (PVC) hard material process flow
