Biodegradable Plastics With its platy structure, food-grade talcum powder (TPB series) is free of harmful substances such as lead, barium, and arsenic. When added to biodegradable plastics, it improves various properties such as tensile strength, rigidity, creep resistance, heat resistance, and surface hardness. Research shows that talc acts as an effective nucleating agent in polylactic acid (PLA), significantly improving its crystallization speed and degree. This leads to enhanced mechanical properties and heat resistance, making talc an ideal additive for PLA, PBAT, PBS, and other biodegradable plastics.
