Life cycle assessment of thermoplastic starch
Web01. jan 2024. · The mechanical properties of TPS depend upon the process temperature, moisture in the starch, and nature and quantity of the plasticizer used. Plasticizers have … WebThey are molten when heated and harden upon cooling. When frozen, however, a thermoplastic becomes glass-like and subject to fracture. These characteristics, which lend the material its name, are reversible, so the material can be reheated, reshaped, and frozen repeatedly. As a result, thermoplastics are mechanically recyclable.
