Smoke suppressants for engineering plastics are specialized functional additives developed and produced by Taixing, specifically designed to address the industry pain points of ABS, PC/ABS, PP, PA and other engineering plastics, such as flame retardancy but excessive smoke, mechanical property degradation, and poor processing adaptability. Different from the broad-spectrum and low efficiency shortcomings of general smoke suppressants, this product achieves a quadruple breakthrough of efficient smoke suppression, synergistic flame retardancy, mechanical protection, and process friendliness. It can be compounded with various flame retardants such as phosphorus nitrogen series, expansion type, hydroxide, etc., greatly reducing smoke density and toxic gas release. It is the core additive of high-end engineering plastic products.
Using montmorillonite zinc borate nanointercalation composite technology, a dual effect smoke suppression structure of "layered barrier+free radical capture" is constructed; The grafting modification process of specialized compatibilizers for supporting engineering plastics forms an active functional group layer on the surface of the additive particles that precisely matches the molecular chain of the substrate, completely solving the problems of material brittleness and reduced processing flowability caused by inorganic additive aggregation. The particle size of the product is precisely controlled between 50-100nm, with a specific surface area that is 55% higher than traditional smoke suppressants. The smoke suppression efficiency is over 65% higher than that of general zinc borate products, and its compatibility with engineering plastics has reached an industry-leading level.
1. Targeted smoke suppression and toxicity reduction: The nano intercalation structure can quickly capture the core components of smoke particles (carbon black, polycyclic aromatic hydrocarbons) during the combustion stage, while releasing boron containing gas phase components, targeting and quenching active free radicals such as · OH and · H in the combustion chain reaction, and cutting off the pathway of toxic gas generation; Reduce the smoke density rating (SDR) of engineering plastics by 60% -70%, and ensure that the release of toxic gases meets the requirements of GB/T 20285-2006 standard, achieving low smoke and low toxicity.
2. Synergistic flame retardancy and efficiency enhancement: When the zinc borate component in the smoke suppressant is combined with the flame retardant, it can promote the formation of a dense and high-strength ceramic carbon layer on the surface of the substrate. This carbon layer not only blocks oxygen and heat transfer, but also adsorbs smoke particles and inhibits their escape, increasing the material's oxygen index by an additional 3-5 units and making the flame retardant performance more stable and durable.
3. Interface compatibility protection: The grafted specialized compatibilizer molecules form physical entanglement and chemical cross-linking with the engineering plastic molecular chains, filling the interface gaps between inorganic additives and organic substrates to avoid a decrease in material tensile strength and impact toughness; The impact strength retention rate of ABS products after addition is ≥ 92%, and the bending strength retention rate of PC/ABS products is ≥ 90%, fully meeting the structural performance requirements of high-end products.
1. Efficient smoke suppression, with smoke toxicity indicators far exceeding industry standards
-Outstanding smoke suppression efficiency: When combined with phosphorus nitrogen flame retardants for ABS household appliance shells, the smoke density grade (SDR) is reduced by more than 65%, the smoke generation rate (SPR) is reduced by 55%, and there is no visible black smoke overflow;
-Low toxicity and environmental protection: There is no release of toxic and corrosive gases such as hydrogen halides and cyanides during combustion, and the concentration of toxic gases (excluding CO and CO ₂) is ≤ 500ppm, which complies with strict smoke and toxic standards such as EN 45545 for rail transit and ISO 6722 for automotive interiors;
-Collaborative flame retardant does not conflict: When compounded with various flame retardants, it has no antagonistic effect and can instead improve the stability of the flame retardant system, helping materials easily pass UL94 V-0 and GB 8624-2022 B1 level flame retardant tests.
2. Mechanically friendly, ensuring the core performance of engineering plastics
-Excellent compatibility: Perfectly compatible with mainstream engineering plastics such as ABS, PC/ABS, PP, PA6, PBT, etc., evenly dispersed without agglomeration, without affecting the melt index and processing flowability of the material;
-Significant mechanical protection: When the addition amount is only * * 3% -8% * *, efficient smoke suppression can be achieved, and there is no significant negative impact on the mechanical properties of the substrate. The impact resistance, bending resistance, and tensile performance retention rate of the product are all ≥ 90%;
-No impact on appearance: The whiteness of the product is ≥ 93, and the addition does not change the natural color of the engineering plastic, nor does it affect the subsequent precision processing steps such as spraying, electroplating, and coating of the product.
3. Process friendly, compatible with mainstream processing methods of engineering plastics
-Wide processing temperature window: able to withstand high temperature processing environments of 200-300 ℃, suitable for mainstream engineering plastic processing processes such as injection molding, extrusion, blow molding, etc., without causing product bubbles, yellowing, or color difference due to high temperature decomposition;
-No need to adjust equipment parameters: can be directly blended with engineering plastic raw materials and flame retardants for granulation, without the need for additional dispersants or lubricants, reducing production and debugging costs and time for enterprises;
-High batch stability: The product has a narrow particle size distribution and a performance fluctuation error of ≤ 3%, ensuring stable and consistent product quality during large-scale production.
4. Global compliance helps ensure worry free export of high-end products
-100% halogen-free, antimony free, and heavy metal free, fully certified by authoritative standards such as EU RoHS 2.0, REACH (224 SVHC), US UL94 V-0, ASTM E84, etc;
-Meet the requirements of specialized systems such as IATF 16949 in the automotive industry and IPC-A-610 in the electronics industry, and can be used in high-end fields such as automotive interior parts, electronic and electrical enclosures, and rail transit components;
-The combustion residue is a stable and harmless inorganic compound that can be recycled and reused, meeting the circular economy requirements of the EU WEEE directive.
Q1: What is the core difference between this smoke suppressant and a universal smoke suppressant?
A1: General smoke suppressants are mostly single component, with low smoke suppression efficiency and easy to lead to a decrease in material mechanical properties; This product is a nanocomposite modified formula designed specifically for engineering plastics. It has the triple effects of efficient smoke suppression, synergistic flame retardancy, and mechanical protection, with better adaptability and performance.
Q2: Can it be used for transparent engineering plastic products (such as transparent PC)?
A2: Sure. For transparent materials such as PC, ultra-fine transparent formulas can be customized, with a light transmittance retention rate of ≥ 85% after addition, meeting the smoke suppression and flame retardant requirements of transparent products.
