Product Description

 

Desription

Small particle size, low scattering, high transparency-ideal for transparent or high-gloss products.

Excellent dispersion and high activity, compatible with various resins, preventing flocculation and floating.

High L° value, delivering ultra-high gloss and vivid color to product surfaces.

Low impurities, free of harmful substances, ensuring safety and surface cleanliness.

Highly inert-resistant to acids, alkalis, high temperatures, UV, and weathering.

Low oil absorption, superior leveling performance.

Uniform particle size, maintaining mechanical properties-narrow distribution, low surface area, and reduced base material usage.

High thermal conductivity and rheology, shortening plasticizing and molding cycles.
