TOROWHITE FIL 04 as a functional additive increases the thermal and mechanical properties of the biopolymer matrix in conjunction with other additives while decreasing the costs substantially. In biodegradable plastics such as polylactide (PLA) optimum results with improved functionalities are obtained at 20-40% FIL 04 levels in the respective composites. In highly filled PLA composites containing 40% of FIL 04, the co-addition of up to 10% impact modifier can significantly improve impact properties, leading to 2-3 times increase in impact strength. TOROWHITE FIL 04 can also be used to significantly improve the flame retardant property of polylactide (PLA) based polymers utilized in conjunction with other additives. PLA composites containing FIL 04 with other as flame retardant without halogens are classified “VO” ( in the case of 25% FIL 04) and “V2“ (in the case of 40% FIL 04).* FIL 04 displays excellent dispersion properties in compounds with PLA based polymers.
