Chain extension of polyamides
The NEXAMITE® product range for polyamides/nylons offers melt strength and viscosity modification and is made up of linear chain extenders and long chain branching agents.
The linear chain extender NEXAMITE® A99 provide increased molecular weight during the melt processing of the polyamide. This effect is beneficial in e.g. extrusion applications of filaments, where process stabilization and increased mechanical properties are desired.
Our latest innovation NEXCIRCLE™ R801 is specifically designed to offer chain extension and viscosity increase in recycled polyamides, r-PA. As with many recycled polymers, they lose part of their original performance when they are recycled, but a large portion of this can be restored by chain extension.
