The Halogen free eco flame retardant for PP, developed and produced by Taixing, adopts a green formula system of bio based carbon source, phosphorus nitrogen synergistic effect, and mineral enhancement. It replaces traditional petrochemical based carbonization agents with biomass charcoal derived from agricultural waste. At a dosage of 30%, it can achieve UL 94 V-0 flame retardant for 1.6mm PP products, while endowing the products with partial biodegradability, providing a triple core guarantee of "flame retardant compliance, ecological friendliness, and non-destructive performance" for fields such as new energy vehicles, green building materials, and biodegradable packaging.
1. Fully ecological formula design, environmentally friendly from raw materials to waste
-Biobased core components: using agricultural waste such as straw and rice husk as raw materials to prepare biomass charcoal, with a biobased content of ≥ 60%. It has passed the American ASTM D6866 biobased content certification, significantly reducing the product's carbon footprint and helping customers obtain carbon reduction credits.
-Zero halogen and zero heavy metal: The halogen (Cl+Br) content is ≤ 300ppm, and the heavy metal content such as lead, cadmium, mercury is ≤ 1ppm, fully meeting the strict standards of EU RoHS 2.0 and California Prop 65. There is no release of corrosive hydrogen halide gas during combustion, and the smoke toxicity reaches the highest safety level of EU EN 13501-1:2024.
-Partially biodegradable: PP products with added flame retardant have a biodegradation rate of ≥ 15% in soil environment after 12 months, which is much higher than the degradation level of traditional flame retardant PP products. After disposal, they can be safely disposed of through composting or biological treatment to avoid the risk of "white pollution".
2. Phosphorus nitrogen mineral synergistic effect, achieving efficient flame retardancy with low addition amount
-Triple synergistic flame retardant mechanism: Adopting a bio based carbon source+ammonium polyphosphate (APP, purity ≥ 99.8%)+modified magnesium hydroxide ternary composite system, during combustion, a dense and high toughness expanded carbon layer is formed through the triple action of "gas-phase free radical capture+condensed phase expansion into carbon+mineral insulation", with a carbon layer expansion rate of 16:1, effectively blocking oxygen and heat transfer.
-Excellent flame retardant performance: Adding 30% to 1.6mm thick PP products can stably meet UL 94 V-0 flame retardant standards, with a limit oxygen index (LOI) of ≥ 34%; 3.0mm thick products can pass the GB 8624-2012 Building Materials B1 level flame retardant certification without the need for additional synergists, solving the pain point of high addition of traditional halogen-free flame retardants.
-Non droplet characteristic: There is no droplet phenomenon during the combustion process, greatly reducing the risk of fire spread, especially suitable for scenarios with high fire safety requirements such as automotive interiors and building ventilation ducts.
3. Interface modification optimization, ultimate compatibility with PP substrate
-Composite coating modification technology: Adopting a double-layer coating process of silane coupling agent+PP-g-MAH grafting, an affinity layer highly matched with PP molecular chains is constructed on the surface of flame retardant particles, which improves interface compatibility by 70% and completely solves the problems of uneven dispersion, aggregation and whitening of traditional halogen-free flame retardants.
-Accurate particle size control: The average particle size D50 is precisely controlled between 1.8-2.2 μ m, with a particle size distribution span of ≤ 0.6 μ m. It is tightly bonded to the PP matrix, and the processed product surface is smooth without any pockmarks or flow patterns. It is suitable for scenarios with strict appearance requirements such as home appliance panels and automotive center controls.
-Wide processing temperature window: 1% thermal weight loss temperature ≥ 325 ℃, processing temperature range covers 180-240 ℃, accurately matched with processing temperatures of various substrates such as homopolymer PP, copolymer PP, high impact PP, etc. High temperature processing has no decomposition, yellowing, or gas evolution, and does not affect the forming accuracy of the product.
4. Low performance loss, ensuring the core advantage of PP substrate
-High retention rate of mechanical properties: The retention rate of tensile strength of PP substrate is ≥ 94%, the retention rate of notch impact strength is ≥ 92%, and the decrease in bending modulus is ≤ 4%. It perfectly solves the industry problem of "flame retardant compliance and material brittleness" of traditional halogen-free flame retardants, and meets the dual requirements of strength and toughness for structural components.
-Excellent weather resistance and corrosion resistance: After 1000 hours of xenon lamp aging test, the retention rate of flame retardancy and mechanical properties is ≥ 91%; After acid and alkali corrosion testing (soaking in 5% hydrochloric acid/sodium hydroxide solution for 72 hours), the product showed no cracking or discoloration, making it suitable for complex environments such as outdoor building materials and chemical pipelines.
