How to make PVC raw materials for PVC machine

PVC Resin:

PVC resin serves as the primary ingredient, typically provided in granular or powder form. It forms the base of PVC compound, determining the physical properties and processing characteristics of the final product.

Additives:

Plasticizers: Used to enhance flexibility and processability of PVC.

Stabilizers: Prevent PVC from decomposing during processing and use.

Fillers: Such as calcium carbonate, used to reduce costs, increase strength, and improve physical properties.

Colorants and Pigments: Used for coloring PVC compounds.

Antioxidants: Prevent PVC from aging during processing and use.

Lubricants: Improve flow and processing characteristics of PVC.

Processing Aids:

Enhance processing performance and manufacturability of PVC compounds, such as flow agents and surfactants.

Mixing Process:

Formulation Design:

Based on the requirements and performance specifications of the final product, design the formulation of PVC compounds. Determine the proportions of PVC resin, various additives, and processing aids.

Dry Blending:

Place PVC resin, fillers, pigments, and other additives into a mixer or dry blending equipment for mixing and even distribution. This process ensures uniform dispersion of additives in PVC resin.
