Ucwax 108A for PVC Pipes and Fittings, The Addition Amount Is About 0.5% - 1.2%. It Can Improve The Fluidity of Plastics During The Extrusion Molding Process
UCWAX 108A General Range of Addition Amounts The addition amount of polyethylene wax in PVC products is usually between 0.1% and 3%. However, this range is not absolute, and the actual addition amount may vary depending on factors such as the specific use of PVC products, processing techniques, and the types and quantities of other additives. Specific Situations of Different PVC Products Profile Processing In the production of PVC profiles, the addition amount of polyethylene wax is generally around 0.8% - 1.5%. This addition amount helps to control the plasticizing process of the profiles, improve their surface glossiness, and enable the profiles to be more easily demoulded during the extrusion process. For example, in the production of PVC profiles for doors and windows, an appropriate amount of polyethylene wax can make the surface of the profiles smoother and the appearance quality better. Pipes and Fittings For PVC pipes and fittings, the addition amount is approximately 0.5% - 1.2%. It can improve the fluidity of the plastic during the extrusion molding process, make the molding of pipes and fittings more uniform, reduce surface precipitation at the same time, and ensure the quality and performance of the pipes. For example, in water supply pipes, adding an appropriate amount of polyethylene wax can prevent additives from precipitating on the inner wall of the pipes, ensuring the hygienic performance of the pipes. Masterbatch Application When masterbatches are used in PVC hard products (such as profiles, pipes, etc.), the addition amount of polyethylene wax may reach 2% - 3%. This is because in masterbatches, good pigment dispersibility is required, and polyethylene wax can help pigments to be evenly dispersed in the PVC matrix, thus ensuring the uniformity and stability of colors. Other PVC Products (Blinds, Wood-Plastic Composites, Pellets, etc.) In the processing of PVC blinds, the addition amount is about 0.6% - 1.0%, which can improve their surface gloss and demoulding performance. In wood-plastic composite materials, the addition amount may be between 0.8% - 1.8%, which helps to mix plastics and wood fibers and improve processing performance. For PVC pellets, the addition amount is around 0.3% - 1.0%, mainly to improve the fluidity and lubricity of the pellets.
