Core Insights - The talc powder industry is transitioning from being a "common filler" to a "functional particle," with HPCL co-modification technology as a key driver. This technology aligns with global plastic reduction policies and meets the three demands of biodegradable plastics: high filling, high toughness, and high flow [2] - The global market for talc powder is projected to reach $1.383 billion in sales by 2024 and $1.718 billion by 2031, with a compound annual growth rate (CAGR) of 3.2% from 2025 to 2031 [2] Group 1 - The HPCL technology addresses the industry pain point of insufficient particle size distribution in domestic talc powder, with less than 30% of particles being ≤2μm [3] - Mechanical testing shows that adding HPCL reverses the brittleness of the PLA/talc powder system, increasing impact strength from 4.3 kJ/m² to 7.7 kJ/m² and elongation at break from 3.9% to 6.44% when 7 parts of HPCL are added [3] - The HPCL's spherical topology reduces molecular chain entanglement, enhancing the flow properties of the high-filling system, making it suitable for high-end applications like thin-walled transparent packaging and 3D printing materials [4] Group 2 - The melt flow rate of the PLA/talc powder base formula increased from 17.5 g/10min to 30.6 g/10min with the addition of 7 parts HPCL, representing a 74.6% increase [4] - The thermal stability of the system remains high, with decomposition temperatures exceeding conventional processing temperatures, ensuring compliance with EU REACH standards for heat resistance [4] - The report includes a comprehensive analysis of the Russian talc powder market, including current market size, capacity, production, sales revenue, and future forecasts [5][6]
