TPS Plasticized Starch J — Thermoplastic Starch, Plasticized Grade J
TPS Plasticized Starch J is derived from plant starches (like corn or potato) plasticized with agents such as glycerol or sorbitol to improve its workability and flexibility. It is highly biodegradable and compostable, suitable for disposable items and packaging where cost-effectiveness and environmental impact are key considerations.
