Core Applications in Downstream Engineering

The primary downstream application for this versatile additive is in engineering plastic modification. When incorporated into formulations, it significantly reduces internal friction between polymer chains and between the polymer melt and processing equipment. This leads to several tangible benefits:

• Improved Mold Release: Acts as an exceptional脱模剂, preventing finished products from sticking to molds. This results in faster cycle times, reduced downtime for cleaning, and perfect surface finish on molded parts.
• Enhanced Lubrication: Its润滑 properties lower melt viscosity, allowing for smoother flow, reduced energy consumption during extrusion or injection molding, and decreased wear on machinery.
• PVC Heat Stabilization: While primarily a lubricant, it also functions as a co-stabilizer in PVC formulations, aiding in processing stability and protecting the polymer from thermal degradation.
• Dispersion Aid: Helps in the uniform dispersion of other additives like pigments and fillers within the plastic matrix, ensuring consistent product quality.
