Kimya TPC-91A is a 3D printing filament made from thermoplastic copolyester (TPC), a type of elastomer. This material combines rigid ester segments and flexible ether segments through copolymerization, giving it both flexibility and durability. TPC-91A offers excellent chemical and impact resistance along with a Shore hardness of 91A, making it well-suited for producing flexible parts. It’s used across various industrial sectors like electronics, textiles, and roofing, as well as in decorative and leisure 3D printing applications.
