Applications of PVC, PE, PP, and EVA Powders

PVC, PE, PP, and EVA powders are versatile polymer materials with extensive applications across various industries. These powders, characterized by their fine particle size and excellent processability, serve as fundamental raw materials in numerous manufacturing processes.

Rotational Molding and Coating
A primary application of these polymer powders is in rotational molding, particularly for creating large, hollow products like storage tanks, playground equipment, and outdoor furniture. PE and PP powders are especially favored in this field due to their impact resistance and weatherability. Additionally, these powders are widely used in coating technologies. PVC powders, for instance, are essential for metal coating applications, creating protective layers on wire racks, fencing, and other substrates through the plastisol process.

Additive Manufacturing and Composite Production
With the advancement of 3D printing technologies, polymer powders have gained significance in additive manufacturing, particularly in selective laser sintering (SLS) processes. EVA powder finds substantial application in the footwear industry as a key component in midsole production, providing cushioning and flexibility. Furthermore, all four powder types serve as crucial modifiers in the production of various composite materials, including wood-plastic composites (WPC) and thermoplastic elastomers, where they enhance specific material properties and processing characteristics.

Adhesives, Sealants, and Modifiers
EVA powder's excellent adhesive properties make it valuable in hot-melt adhesive formulations, while PVC powders contribute to the production of sealants and caulks. These polymer powders also function as processing aids and property modifiers in numerous industrial applications, demonstrating their versatility and importance in modern manufacturing.
