DBDPE for ABS Plastic

The DBDPE for ABS plastic produced by Taixing is precisely matched with the synergistic system through core-shell structure coating modification technology, perfectly matching the molecular characteristics of ABS ternary copolymer. While achieving UL 94 V-0 flame retardancy for 1.6mm thickness products, it maximizes the impact resistance and surface smoothness of the substrate. The product is completely free of polybrominated diphenyl ether (PBDE) structure, and does not release carcinogenic dioxins during thermal decomposition. It fully complies with strict global standards and provides the triple core guarantee of "high performance, high compliance, and high appearance" for high-end ABS products.

Core strengths

1. Targeted modified design, extremely compatible with ABS substrate

-By adopting the ABS graft core-shell coating modification process, an elastic shell layer highly matched with ABS molecular chains was constructed on the surface of DBDPE particles, which improved the interface compatibility by 70% and completely solved the industry pain points of uneven dispersion and agglomeration precipitation of traditional DBDPE in ABS.

-The average particle size is precisely controlled within 1.5-2.0 μ m, with a particle size distribution span of ≤ 0.5 μ m. It is tightly bonded to the ABS matrix, and the surface finish of the processed product can reach mirror level, without any blemishes or flow patterns. It is suitable for scenarios with strict appearance requirements such as home appliance panels and automotive center control panels.

-Without the need for additional dispersants or compatibilizers, it can be directly blended with ABS resin for processing, without changing the existing production line parameters such as twin-screw extrusion and injection molding, greatly reducing the cost of enterprise production transformation.

2. Low addition and high flame retardancy, minimizing the loss of impact resistance performance

-Bromine content ≥ 83.5%, combined with 3% -4% antimony trioxide synergist, the total addition amount only needs 12% -18% to make 1.6mm thick ABS products stable and meet UL 94 V-0 flame retardant standards, with a limit oxygen index (LOI) ≥ 34%. The addition amount is reduced by 15% -20% compared to traditional flame retardants.

-The impact resistance of ABS substrate is extremely low, with a retention rate of notch impact strength ≥ 92%, a retention rate of tensile strength ≥ 95%, and a decrease in bending modulus ≤ 3%. It perfectly solves the industry problem of "flame retardant compliance and toughness reduction" and meets the strict requirements of mechanical properties for structural components.

-The thermal stability is precisely matched with the processing temperature of ABS, with a 1% thermal weight loss temperature of ≥ 335 ℃ and a processing temperature window width of 200-240 ℃. It is suitable for various processes such as extrusion, injection molding, and compression molding. During high-temperature processing, there is no decomposition, yellowing, or gas release, and no product bubble defects are produced.

3. Molecular level safety and compliance, green and environmentally friendly throughout the entire lifecycle

-Ethane bridge bonds replace traditional ether bond structures, generating only hydrogen bromide and a dense inert carbon layer during thermal decomposition, without any release of highly toxic substances such as dioxins and furans. The toxicity of combustion smoke meets the highest level of low smoke toxicity in EU EN 13501-1:2024, with a smoke density rating (SDR) of ≤ 42.

-Fully certified by the EU REACH regulation's 250 SVHC list, RoHS 2.0 directive, US TSCA compliance assessment, and California Prop 65 safety standard, it is not included in the Stockholm Convention's POPs control list and can be directly applied to sensitive scenarios such as children's electronic toys and food contact grade ABS products.

-The bioaccumulation factor (BCF) is ≤ 450, and discarded ABS products can be recycled through mechanical recycling processes without harmful substance residues, helping customers obtain green supply chain certification and carbon footprint labels for their products.

4. Customized collaborative solutions to meet the diverse needs of ABS products

-Provide exclusive collaborative formulas for different types of substrates such as universal ABS, high impact ABS, and heat-resistant ABS: universal ABS is compatible with the "DBDPE+antimony trioxide" basic solution; The combination of high impact ABS with a composite system of DBDPE, zinc borate, and impact modifier further enhances toughness; Heat resistant ABS matched with high-temperature stable DBDPE, meeting processing requirements above 250 ℃.

-Introducing an antimony free and environmentally friendly version, using a synergistic agent of aluminum hydroxide zinc molybdate to meet the demand for antimony free flame retardancy in some markets, while maintaining a flame retardant effect of UL 94 V-1 or above.
