Hyperbranched Polyamine Charring Agent (HPCA)

Hyperbranched polyamine charring agent (HPCA)


SWC-100 is a kind of hyperbranched polymerized nitrogen-based charring agent which has high hydrolysis resistance, thermal stability and chemical stability due to its special molecular structure.

It can be combined with flame retardant system such as ammonium polyphosphate (APP), melamine cyanurate (MCA), aluminum hypophosphite and organic hypophosphite. By improving the stability and densification of the carbon layer in the combustion process to achieve the inhibition of combustion and melt droplets behavior, improve the flame retardant properties of polymer materials.
It's mainly used in polypropylene, polyethylene, polystyrene, polymethyl methacrylate and other carbon-poor polymer materials in the field of polymer materials.

For different materials and flame retardant system, the recommended addition ratio is different: 1) such as polypropylene composite materialwith acid source (such as ammonium polyphosphate) complex into a halogen-free intumescent flame retardant (ratio of 3: 1) The total adding amountis 25%, flame retardant up to LIO> 30, UL94- V0 level effect; 2) such as polyethylene composite materialwith acid source (such as ammonium polyphosphate) complex into a halogen-free intumescent flame retardant (ratio of 2 : 1), the totaladding amount is 30%, flame retardant up to LIO> 30, UL94- V0 level effect.

Advantage and Application:
The product has the advantages of good dispersibility, good thermal stability, non-toxic, carbon-forming efficiency and high flame-retardant efficiency. It is widely used in flame-retardant products such as thermoplastics and thermosetting rubber, fiber and textile products with poor carbon Polypropylene, polyethylene, polystyrene, natural rubber, ethylene propylene rubber, butadiene rubber and other polymer composite materials, flame retardant. Normally,recommendation is using of complex, with ammonium polyphosphate, melamine polyphosphate, melamine cyanuric acid and other flame retardants used in combination, the effect is better.
