Polyamide (PA) Processing Aids
Product Description
Dendritic polymers as "the fourth class of new polymer materials", are attractive to the scientific world and industrial circles. The novelty of these materials includes highly branched molecular structure, a large number of surface functional groups, void space in molecules, monodisperse molecular weight distribution and nanoscale dimensions. The structural characteristics of dendritic polymers lead to unique properties such as excellent solubility and dispersion properties, low melt viscosity and solution viscosity, difficult to crystallize and easy to form film, showing unparalleled nano features.

Dendritic polymers are excellent modifiers for polyamide (PA) because of the unique structure and physicochemical characteristics. 1) Improve tensile strength, flexural strength, impact strength and rheological properties (improve melt fluidity, lower plasticizing temperature) in PA6 ; 2) Used as compatilizer for PA6, PP or other nylon, such as PA11, PA1010 , improve both compatibility and mechanical properties; 3) Improve dispersion of glass fibers, carbon fibers and various inorganic fillers in PA6; 4) Decrease spinning temperature of nylon to reduce thermal degradation; 5) Endow PA6 with excellent low temperature toughness, thereby increase performance of low temperature resistance.

Excellent performance of nylon system with dendritic polymers:
·Improve mechanical properties of PA6, such as tensile strength, flexural strength, impact strength, etc.;
·Improve flowability, processability of PA6;
·Lower processing temperature , reduce thermal decomposition of PA6, decrease energy consumption, save cost;
·Improve the low temperature resistance performance of PA6;
·Improve compatibility of PA6 with other nylon systems or other resins such as PP;
·Improve dispersion of inorganic fillers such as glass fiber in the PA system.
