Flexible Extrusion

Processing plasticized compounds via flexible extrusion requires precise rheological and thermal control to ensure homogeneous melting and prevent polymer degradation across high-output production lines. The presence of primary and secondary plasticizers alters melt dynamics, making specialized additive systems essential for proper lubricity and continuous thermal stability throughout flexible extrusion.

In the manufacturing of clear tubing, spiral hoses, gaskets, and soft profiles, selecting the right IKA thermal stabilizer directly determines optical clarity, long-term aging behavior, and resistance to exudation. Our solid Calcium-Zinc (Ca/Zn) and Calcium-Organic systems are engineered specifically for excellent plasticizer compatibility, preventing additive migration and maintaining dimensional stability in flexible extrusion.

For demanding applications—such as medical tubing, electrical cables, and weatherstripping profiles for automotive or construction uses—we supply high-purity solid formulations compliant with low Volatile Organic Compound (VOC) emissions. These additives provide extruded soft profiles with high resistance to yellowing, superior surface finish, and retention of mechanical tensile strength.


Operational Note: IKA does not produce or supply liquid stabilizers, focusing research and development exclusively on high-performance solid systems that are heavy-metal-free and optimized for sustainable processing in flexible extrusion.
