PVC profile performance classification The PVC profile with added functional additives has anti-aging, anti-ultraviolet, anti-corrosion, high strength, low price, good heat preservation and heat insulation performance, and can partially replace aluminum profiles and steel. The pollution is lower tha... read more
The PVC plastic profile is mainly composed of PVC resin and additives. The additives are further divided into: heat stabilizer, lubrication agent, processing modifier, impact modifier, filler, ageing agent and colorant. Wait. Before designing a PVC formulation, you should first understand the proper... read more
The PVC resin is converted into a molten state under heat and shear during processing. This melt flow behavior is usually explained by molecular structural parameters such as molecular mass, molecular mass distribution, and branched structure. With the deepening of research and the accumulation of p... read more
Modern rigid PVC profile processing uses a twin-screw extruder to directly extrude the mixed powder, and its plasticizing mixing capacity and output are greatly improved. However, the positive displacement conveying capacity of the twin-screw extruder is much greater than the mixing capacity of the ... read more
After the dry mix leaves the mixing system, it usually passes through a screening step before entering the storage system to screen out the coarse particles in the dry mix. The incorporation of these particles into the dry blend can affect the quality of the extruded product, such as the formation o... read more
