Polymers are increasingly used in new and varied applications where specific mechanical, properties are required. A chain extender, reacts with the functional groups of linear polymer chains to extend the molecular chains and increase their molecular weight.
REGRANYL 90 is an additive for PA 6, PA 6.6, PA 12 and copolymers. It works as chain externder and re-polymerization agent, by reactive extrusion process.
- To increase viscosity of the polymer and the relatives mechanical properties;
- To increase the pressure of the die
REGRATEX MB-D is an additive designed for PET intrinsic viscosity enhancement, used to keep or to improve the viscosity and molecular weight during melt state processing. REGRATEX MB-D is suitable for both homo or copolymer PET, virgin or recycled. REGRATEX is the best solution to increase intrinsic viscosity of PET, during recycling process.
