Huajin ABS 275 is a high-performance matte flame-retardant injection molding grade Acrylonitrile-Butadiene-Styrene (ABS) copolymer resin developed by Huajin Corporation, a leading petrochemical enterprise in China. Utilizing a bulk or emulsion polymerization process (depending on the production line), this grade is supplied as matte flame-retardant pellets characterized by high uniformity and excellent melt processability, making it ideal for high-volume injection molding applications.
In the high-performance specialty ABS market, Huajin ABS 275 has established itself as a benchmark base material across the home appliance, automotive, and electronic enclosure industries due to its excellent balance of impact strength and rigidity, stable melt index, outstanding flame-retardant properties, and superior heat resistance. Its typical downstream applications include television enclosures, air conditioner panels, toy building blocks, suitcase shells, and automotive interior trims.

The technical data sheet (TDS) of Huajin ABS 275 material from Huajin Corporation, if there are differences, please refer to the official website of Huajin Corporation. > (The above data is for reference purposes only. In the event of any discrepancies with the official data published by Huajin Corporation, the official specifications on Huajin Corporation’s website shall prevail.)
Balanced Mechanical Performance: Features a tensile yield strength of 37.6 MPa and a flexural modulus of 1610 MPa, achieving an excellent balance of rigidity and toughness to meet the load-bearing requirements of structural components.
Excellent Processing Flowability: With a melt flow index of 9.52 g/10min, it ensures fast mold cavity filling during injection molding and minimizes flow marks, making it highly suitable for complex, thin-walled parts.
High Surface Hardness: Boasting a Rockwell hardness of R 104.1, the molded parts exhibit superior scratch and abrasion resistance, making it ideal for cosmetic exterior components.
Good Impact Resistance: Exhibits a Charpy impact strength of 10.25 kJ/m², enabling it to withstand moderate energy impacts at room temperature and reducing the risk of cracking during transit and end-use.
Adequate Thermal Stability: With a Vicat softening point of 100.23°C, it reliably withstands the operating temperatures of standard consumer goods, such as heat-generating environments inside household electrical appliances.
With its cost-effectiveness and exceptional batch-to-batch consistency, Huajin ABS 275 is widely utilized in the following industries:
Household Appliances: Indoor air conditioner panels, refrigerator door handles, vacuum cleaner housings, electric fan bases, and related components.
Toys & Children’s Products: Toy bricks, interlocking educational blocks, and model car shells, benefiting from a finish free of sharp flashes, ease of coloration, and baseline RoHS compliance.
Automotive Interiors: Dashboard decorative trims, air conditioning vent louvers, cup holders, and other non-structural, low-stress components.
Consumer Goods & Housewares: Suitcase luggage trolley handles, safety helmet shells, stationery cases, photo frames, and consumer electronics.
Electronics & Electrical Devices: Junction boxes, socket switch faceplates, and battery enclosure bases fitted for applications requiring flame retardancy and high-temperature resistance.
Q1: Is Huajin ABS 275 suitable for food-contact applications?
A: This grade is primarily formulated as a specialty functional ABS resin and is not explicitly certified for food-contact applications. If you plan to use it for food-contact utensils (such as tableware or water cup components), please request an official Food Contact Compliance Declaration from Huajin Corporation and perform final product testing in accordance with local regulations (such as GB 4806.7 or FDA 21 CFR 181.32).
Q2: What are the recommended injection molding processing parameters for this material?
A: Based on its melt index of 9.52 g/10min, the recommended processing window is as follows:
Cylinder/Barrel Temperature: 200–230°C (from rear zone to front nozzle)
Mold Temperature: 40–70°C
Injection Pressure: 60–100 MPa
Drying Conditions: Pre-dry at 80°C for 2–4 hours (ensuring residual moisture content <0.1%)
(Actual parameters should be fine-tuned based on the specific part geometry and injection molding machine model.)
Q3: Does Huajin ABS 275 offer a price advantage compared to standard general-purpose ABS?
A: Huajin ABS 275 is positioned as a high-performance specialty ABS compounding resin that integrates flame retardancy, heat resistance, and high strength. Because Huajin Corporation possesses fully integrated upstream production capabilities for core feedstocks (butadiene, styrene, and acrylonitrile), its ex-factory price is typically more competitive than imported brands with similar engineering properties (such as LG ABS HI-121H or Chimei PA-757). Actual prices fluctuate according to weekly petrochemical plant listings, and we recommend sourcing via authorized distributors for optimal volume discounts.
