As an important inorganic filler in the field of plastic modification, talc powder has a significant impact on the mechanical properties, processability, and functional characteristics of polymer composites due to its particle size parameters. After more than ten years of technological research, Liaoning Xinda Talc Group Co., Ltd. has established a modification system based on particle size morphology interface synergistic regulation, revealing the reinforcement mechanism of talc powder with different particle sizes in matrices such as polypropylene (PP) and polyethylene (PE). 

Every effort deserves respect, and every drop of sweat shines brightly

Talc powder, as a key inorganic filler, plays a crucial role in water-based coatings. However, the calcium content in talc powder may have a negative impact on the performance of the coating. This study explores in depth the sources, mechanisms of action, and solutions of calcium, aiming to clarify the specific impact of calcium content in talc powder on the performance of water-based coatings and provide technical reference for the coating industry. Through measures such as raw material control, formula optimization, and process improvement, the adverse effects of calcium impurities on coating performance can be effectively reduced, and the application effect of talc powder in water-based coatings can be improved.

From April 15th to 18th, the four-day 2025 International Rubber and Plastic Exhibition Chinaplas came to a grand end in Shenzhen.

All along, Xinda Talc Group has deeply rooted the concept of environmental protection in the core of its corporate development. Its factories actively explore the journey of green development, practice their environmental mission with practical actions, and contribute to the sustainable development of this blue planet.

This article focuses on the application and advantages of ultrafine talc powder with high aspect ratio in polypropylene plastics. Firstly, the sheet-like structure and bonding method of talc powder were introduced, and then the technical difficulties in the production process were analyzed. Subsequently, based on the research and development achievements of Liaoning Xinda Talc Group R&D Center, the significant effect of its 3000 mesh talc powder in protecting large scales was introduced, and the superior diameter to thickness ratio of its talc powder was demonstrated through comparative images. Finally, the practical application effects and market feedback of high aspect ratio talc powder in plastics were summarized.

Liaoning Xinda Talc Group Co., Ltd. was established in 1995 and is an enterprise group that integrates talc mining, sorting, research and development, deep processing, and sales.

On March 18, 2025, Xinda Group welcomed a delegation of important Japanese clients for a visit.

Talc, as a type of layered silicate mineral, has significant application value in the field of plastic modification due to its unique sheet-like structure and mechanical properties.
