Attributes like long-lasting durability, hardness, insulating capacity, heat resistance, weather resilience, and sustained performance over time are frequently hailed as the defining strengths of ASA plastic. Owing to these exceptional characteristics, ASA plastic has steadily established a firm presence across a diverse range of manufacturing sectors, including the automotive technology industry, outdoor campus construction, amusement park facilities, backyard landscaping, and various applications within the electrical field.
1. An Overview of ASA Plastic
ASA plastic has long stood out as a top contender for many investors and manufacturers, thanks to its economic advantages and leading performance in the materials industry. Known formally as Acrylonitrile Styrene Acrylate, ASA is a synthetic, amorphous thermoplastic with the chemical formula C18H23NO2. It is produced by adding a powdered grafted acrylic ester elastomer during the copolymerization of acrylonitrile and styrene, with butadiene rubber playing a vital role in the production process. In terms of performance, ASA plastic boasts excellent weather resistance, heat resistance, and impressive resistance to chemicals, ultraviolet (UV) radiation, and certain other forms of radiation.
Currently, ASA plastic is widely utilized in various manufacturing processes, such as hot pressing, injection molding, extrusion, blow molding, and 3D printing. Its superior weather and radiation resistance make ASA plastic an ideal choice for outdoor applications. Industries with high demand for ASA plastic include automotive technology, electronic equipment, and outdoor tools — all fields that Qingdao Zhongxin Huamei has long served with customized ASA solutions.
As a joint venture with Chi Mei Industrial, Qingdao Zhongxin Huamei specializes in the R&D, production, and customization of modified and dyed ASA plastic particles, providing one-stop plastic material solutions for global clients in 5G, new energy, automotive, and home appliance industries. Our ASA products are manufactured with imported colorants and additives, adopting CHIMEI’s self-developed computer color matching and quality control system to ensure consistent color and stable performance batch by batch.
2. Key Properties of ASA Plastic
As previously mentioned, ASA plastic is highly regarded for its durability, hardness, impact resistance, and exceptional weather resistance. Specifically, ASA plastic exhibits a broad range of heat resistance, spanning from very low to very high temperatures, making it suitable for diverse weather conditions worldwide. Additionally, ASA resin demonstrates resistance to various chemicals, including salt solutions, weak acids and alkalis, oils, and saturated hydrocarbons. Due to these properties, products made from ASA plastic consistently maintain their mechanical durability, color, and attractive glossy surface even after prolonged exposure to outdoor environments. However, it is important for manufacturers to note that ASA plastic can be affected by esters, ethers, ketones, and chlorinated hydrocarbons — a detail our technical team at Qingdao Zhongxin Huamei will fully inform clients of during the customization process.
Below are specific statistical data regarding the properties of ASA plastic (tested by our professional laboratory with 100+ sets of testing equipment):
Flexural Strength: 38.6 - 78.6 MPa
Flexural Modulus: 1,413 - 2,606 MPa
Glass Transition Temperature: ≅ 112 °C
Heat Deflection Temperature (1.8 MPa): ≅ 92 °C
Tensile Strength: 35.0 - 50.5 MPa
Tensile Modulus: 1,786 - 2,468 MPa
Elongation at Break: 25 to 40%
Elongation at Yield: ≅ 5.01%
The fire resistance of ASA plastic can reach the UL94HB level, and it releases a benzene and rubber odor during combustion. For clients with higher flame-retardant requirements, Qingdao Zhongxin Huamei can customize ASA plastic that meets UL94 V-0 standards, fully complying with RoHS and REACH EU regulations. Chemically, materials with properties similar to ASA plastic include ABS and AES, whose corresponding rubber phases are polybutyl acrylate, butadiene/styrene copolymer, and ethylene/propylene copolymer, respectively. It is worth noting that the lower the rubber content, the greater the durability and impact resistance of products made from ASA plastic. Furthermore, ASA plastic’s co-extrusion capability allows it to be compatible with PVC and PC materials — a feature we fully leverage in our customized solutions for clients.
3. Processing Methods for ASA Plastic
3.1 3D Printing with ASA Plastic – Process Details
Given its inherent properties, ASA plastic is well-suited for 3D printing processes. To achieve optimal results when 3D printing with ASA plastic, it is essential to adjust key printing parameters, such as part size and shape, machine temperature, and printing speed. Based on our 29 years of manufacturing experience, the ideal extruder temperature ranges from 240 to 250 degrees Celsius, while the bed temperature should be set between 90 and 130 degrees Celsius. The recommended printing speed is 50-90 mm per second. Another critical consideration is that ASA resin must be dried and kept dry throughout the 3D printing process. Additionally, a heating bed is required, and the printing bed must be completely sealed to ensure the best printing outcomes. Before initiating the printing process, our technical team at Qingdao Zhongxin Huamei will help clients verify the data and parameters of the ASA material to ensure it meets the requirements of their specific processing procedure.
3.2 Injection Molding with ASA Plastic
In addition to 3D printing, ASA plastic is also an excellent choice for injection molding. In this process, ASA plastic undergoes a thermoplastic mixing stage. Due to the high gloss of ASA plastic alloy produced by Qingdao Zhongxin Huamei, the finished products typically do not require post-processing, reducing production costs and improving efficiency for our clients. Some notable properties of ASA injection molding include minimal creep even at high temperatures (up to 130 degrees Celsius), good toughness at low temperatures (down to -100 degrees Celsius), heat and electrical insulation, weather and UV resistance, high surface gloss, remarkable strength and stiffness, and antibacterial properties — all of which can be customized according to client needs.
To achieve the best results in ASA injection molding, refer to the following recommended parameters (summarized by our engineering team based on thousands of successful cases):
Drying temperature: 80 degrees Celsius
Drying time: 3-4 hours
Mold temperature: 40～80 degrees Celsius
Residual material: 3～10 mm
Melting temperature: 220～270 degrees Celsius
Back pressure: 5～15 MPa
Injection pressure: 70-120 MPa
Screw speed: 50-90 rpm
Shrinkage: 0.4%-0.7%
Injection speed: Moderate
