APP-I Flame Retardant

APP-I is not a simple ammonium polyphosphate (APP) model, it is an intelligent synergistic flame retardant system that has undergone precise molecular design and surface engineering treatment. The APP-I flame retardant produced by Taixing innovatively adopts the core technology of low-temperature directional polymerization+modified coating optimization, and constructs a triple system of "rapid carbonization barrier phosphorus nitrogen synergistic flame suppression broad-spectrum compatibility adaptation". With only 15% -30% addition, it can achieve the UL 94 V-2 level and above flame retardant effect of materials, completely solving the industry pain points of "strong moisture absorption, poor compatibility, and high precipitation risk" of traditional APP-I, and providing a flame retardant solution that combines cost advantages and compliance guarantees for the global general materials manufacturing industry.

Core strengths

1. Extraordinary flame retardant efficiency and consistency

·Molecular level synergy eliminates the "barrel effect": In traditional physical mixing systems, uneven distribution of any component can lead to localized flame retardant failure. The pre bonding structure of APP-I ensures that the acid source and carbon source are always at the optimal reaction ratio and closest distance at the microscopic level when heated, catalyzing a more rapid and thorough char formation reaction, significantly improving the success rate and batch stability of one-time fire tests (such as UL94 V-0).

·Optimized carbon layer quality and thermal insulation: Its special structure can promote the formation of an expanded carbon layer with finer pores, more continuous structure, and higher strength. The expansion ratio of the carbon layer can be increased by more than 20%, and the residual carbon content is higher, providing superior insulation and oxygen barrier.

2. Excellent processing performance and product performance

·Excellent flowability and dispersibility: The unique particle morphology and surface treatment give it excellent lubrication and dispersion effects in polymer melts. The melt flow index (MFI) can be increased by 15-30% compared to the same flame retardant formula using traditional APP, greatly improving the processing flowability in high filling systems and suitable for complex thin-walled products.

·Significantly improving the mechanical properties of the substrate: By reducing stress defect points caused by uneven physical mixing and lowering the total amount required to achieve the same flame retardant level, APP-I can better preserve the impact strength, tensile strength, and elongation at break of the matrix resin. The surface smoothness of the product is high, effectively suppressing the phenomenon of "frosting".

·Reduce system acidity and corrosion risk: By partially neutralizing the surface acidity of APP through pre bonding technology, the potential corrosion of screws and molds in high-temperature and high humidity processing environments is reduced, and the long-term thermal aging performance of materials is improved.

3. Simplified formula and excellent cost-effectiveness

·Simplified design of "two in one" or "three in one": APP-I can significantly reduce or even eliminate the need for additional separate carbon sources, simplify raw material inventory, ingredient processes, and process complexity, and reduce quality fluctuations caused by weighing errors of multiple components.

·Reducing comprehensive costs: Although the unit price may be higher than that of ordinary apps, its comprehensive application cost has significant advantages due to its higher flame retardant efficiency (which may reduce the total amount of additives), better processability (reducing energy consumption and improving yield), and retention of mechanical properties.

Application scenarios

A. High end polyolefin flame retardant products (PP/PE/TPO)

·Home appliance casings and components: high-end air purifiers, dehumidifiers, and smart home controller casings require V-0 flame retardancy, high surface gloss, and good impact resistance.

·Non metallic parts of new energy vehicles: internal insulation components of battery packs, charging gun casings, and low-voltage wire harness sheaths.

·High end tools and consumer goods: electric tool casings, high-quality luggage frame.

B. Engineering plastic modification (PA, PBT, PET)

·Electronic and electrical connectors: components that require extremely high CTI values, heat resistance, and fluidity.

·LED lighting components: reflector, heat dissipation shell, lamp holder.

·Automotive fans and engine hood components: require long-term heat aging resistance.

C. High performance fireproof coatings and sealants

·Expansion type fireproof coating: As a core flame retardant component, it provides a more stable and long-lasting fireproof expansion effect.

·Fireproof sealant and potting adhesive: used for fireproof sealing of building gaps and cable penetrations.
