Nucleating agent BTA-6008

Scope of application

Amide nucleating agent BTA-6008 is mainly used to optimize the crystallization behavior of polyamides for the following scenarios:

.   PA types: PA6, PA66, PA12 and other semi-crystalline polyamides.

.   Processing: injection molding (precision parts, thin-walled products),

extrusion molding (film, pipe), fiber spinning (industrial silk, textile fibers)

               .   End fields:

o    Automotive industry: engine peripheral parts, gears, connectors (improved heat resistance and dimensional stability).

o    Electrical and electronics: sockets, coil bobbins (enhanced insulation and rigidity).

o    Packaging and films: high barrier films, food packaging (improved surface finish).

o    Fiber Products: High-strength industrial fibers (e.g., fishing nets, ropes).

Functions and Purposes

.   Accelerate crystallization rate: shorten the molding cycle and improve production efficiency (20-40% reduction in crystallization time).

.   Refinement of grain size: Reduce the size of spherical crystals (from tens

of microns to 1-5 μm), reduce material brittleness.

             .   Improvement of overall properties:

o     Increase tensile strength (↑10-20%), flexural modulus (↑15-30%) and heat deflection temperature (HDT ↑10-25℃).

o     Reduce warping and shrinkage of products, enhance dimensional stability.

.   Regulating crystalline morphology: inducing the formation of a more regular crystalline structure (e.g. α crystalline dominant), optimizing    material transparency (in some formulations).

Structures

.   Typical structure:

。 N,N'-Ethylenebis(stearamide) (EBS): contains long chain alkyl and amide groups (-NH-CO-).

o    Aryl-substituted amides: e.g. benzamide derivatives (both rigid and nucleating activity). 

            .   Structure function:

o    Amide group: Forms hydrogen bonds with the amide bonds of the PA molecular chain to enhance interfacial bonding.

o    Long alkyl chains/aromatic rings: provide hydrophobicity and spatial site resistance to promote uniform dispersion of the nucleating agent in the melt.
