How to Use PVC Internal Lubricants in Foamed Board Production

Selection of Lubricants: Choose a lubricant based on the desired properties of the final product, such as flexibility, strength, and resistance to environmental factors.

Compounding: The lubricant is mixed with PVC resin and other additives during the compounding process. The amount and type of lubricant can significantly influence the processing characteristics and the properties of the foamed board.

Extrusion and Foaming: During the extrusion process, the lubricant aids in the smooth flow of PVC, preventing degradation. It also plays a role in the foaming process, influencing the cell structure of the foamed board.

Finishing and Fabrication: The presence of internal lubricants in PVC foamed boards facilitates easier cutting, shaping, and finishing of the boards in various applications.

The use of PVC internal lubricants in the production of foamed boards is essential for optimizing processing and enhancing the qualities of the final product. The choice of lubricant depends on the specific application and desired properties of the PVC foamed board. Proper selection and application of these lubricants can significantly improve the performance and versatility of PVC foamed boards in various industries.
