Disclaimer: The technical data sheet (TDS) of POLYLAC® PA-707K ABS material from Chimei corporation, if there are differences, please refer to the official website of Chimei.
High Melt Flowability: Features a high melt volume-flow rate (23 cm³/10 min at 220°C/10 kg), providing a long flow path and low injection pressure, which significantly improves mold-filling efficiency for large complex parts and thin-walled components.
Balanced Mechanical Rigidity & Impact Resistance: Boasts a flexural modulus of up to 2600 MPa and a tensile strength of 48 MPa. While ensuring high structural rigidity, it maintains good Izod notched impact strength (15 kJ/m²).
Excellent Surface Finish & Processability: Delivers high surface gloss and stable shrinkage after injection molding, making it easy for post-processing such as painting, electroplating, ultrasonic welding, and machining.
Reliable Thermal Stability: Achieves a Vicat softening point of 104°C and a heat deflection temperature of 98°C, ensuring that parts remain structurally stable in ambient to moderate operating temperatures.
Environmental & Food-Contact Compliance: Complies with RoHS and REACH regulations. Specific batches meet food-contact compliance standards (FDA / EU) with low odor and low residual monomer content, making it suitable for applications with high hygiene requirements.
Owing to its high flowability, good mechanical rigidity, and excellent surface appearance, POLYLAC® PA-707K ABS is widely utilized across the following industry sectors:
Q1: What are the recommended drying conditions for POLYLAC® PA-707K ABS prior to injection molding?
A: ABS material is slightly hygroscopic; excessive moisture before processing can cause silver streaks, bubbles, or reduced mechanical strength on the product surface. Recommended drying parameters are as follows:
Drying Equipment: Hot air circulating oven or desiccant dryer.
Drying Temperature: 80°C – 85°C.
Drying Time: 2 – 4 hours (dry until moisture content is controlled below 0.1%).
Q2: What is the difference between POLYLAC® PA-707K and general-purpose standard ABS (e.g., PA-757)?
A: The main differences lie in flowability and rigidity emphasis:
PA-707K focuses on high flowability and high rigidity (higher melt index and superior flowability), making it more suitable for thin-wall molding, large complex injection molded parts, and shorter production cycles.
PA-757 is a high-impact general-purpose grade with slightly higher impact strength, but its melt flow rate is lower than that of PA-707K.
Q3: Does Chimei PA-707K ABS comply with international environmental and flame-retardant certifications (RoHS / UL)?
A: Yes. Chimei PA-707K complies with EU RoHS (2011/65/EU) directives and REACH (SVHC) regulations. Regarding flammability rating, this grade passes the UL 94 HB test at a thickness of 1.5 mm, categorizing it as a standard flammable engineering plastic. If your application requires a V-0 flame-retardant rating, it is recommended to select Chimei POLYLAC® flame-retardant series (such as PA-777D or PA-765).
