High Concentration Flame Retardant for PP

The high concentration flame retardant for PP developed and produced by Taixing adopts high load encapsulation granulation technology to increase the content of flame retardant active ingredients to 60% -80%. Through the molecular compatibility design of carrier resin and PP substrate, it achieves a processing experience of "direct feeding, uniform dispersion, and stable performance". Our products cover two major series: halogen based and halogen-free phosphorus nitrogen synergistic effects, providing efficient and convenient flame retardant solutions for PP products such as automotive parts, electronic casings, and building pipes.

Core strengths

1. High concentration of active ingredients, significantly reducing costs and increasing efficiency

-Active ingredient content of 60% -80%: far exceeding the industry's conventional loading limit of 50%, significantly reducing the proportion of masterbatch added - only 15% -25% of the added amount is needed to make 1.6mm PP products stably meet UL 94 V-0 flame retardant standards, with a limit oxygen index (LOI) of ≥ 32%.

-Accurate measurement with low loss: The granular form avoids powder flying and equipment residue, reducing the feeding loss rate to below 0.5%. The measurement accuracy of the automated production line is improved to ± 0.2%, effectively reducing raw material waste and workshop cleaning costs.

-Processing efficiency increased by 30%: No additional pre mixing process required, directly blended with PP resin for extrusion/injection molding, smooth screw conveying without bridging, equipment cleaning cycle extended by 2 times, significantly reducing production cycle time.

2. Molecular level compatible design, perfectly matched with PP substrate

-Customization of specialized carrier resin: using polyolefin carrier with the same origin as PP, combined with PP-g-MAH graft compatibilizer, the interface adhesion is increased by 70%, completely solving the problem of white spots and rough spots caused by uneven dispersion of traditional masterbatch, and the surface smoothness can reach mirror level.

-Precise particle size control: The mother particle size is evenly distributed between 2-3mm, consistent with the shape of PP resin particles, and melts synchronously during melt blending. The flame retardant components are dispersed at the nanoscale in the matrix, without aggregation or precipitation, ensuring the consistency between the mechanical properties and flame retardant properties of the product.

-Full category PP adaptation: Three series are launched: homopolymer PP special type, high impact PP special type, and heat-resistant PP special type, which match the processing temperature and performance requirements of different types of PP substrates, and can be directly applied without adjusting production line parameters.
