Wear-Resistant Wax Additives for Glass-Fiber Reinforced PA Compounds

Glass-fiber reinforced polyamide (PA-GF) compounds are widely used in automotive and electrical components due to their high strength and thermal stability. However, the presence of glass fibers can cause high surface roughness, increased tool wear, and reduced abrasion resistance. Wax additives offer a solution that addresses both processing and end-use performance.

Technical Benefits

• Wear Resistance: Forms a protective layer on the surface, minimizing abrasion during assembly and in use.

• Improved Surface Quality: Reduces fiber protrusion, resulting in smoother molded parts.

• Enhanced Processability: Lowers melt viscosity for better mold filling and reduced injection pressure.

Technical Considerations

Modified polyethylene waxes with optimized molecular weight are often selected for PA-GF systems due to their compatibility and thermal stability. Formulation tuning is necessary for achieving optimal dispersion and performance.

An automotive supplier used a specialized wax additive in their PA6-GF30 compound, resulting in smoother surfaces, lower mold wear, and improved part durability.
