PC/ASA for Outdoor and Automotive Exterior Parts
Weather Resistant Polycarbonate ASA Blend is a weather-resistant engineering plastic based on a PC/ASA alloy system. It is mainly intended for automotive exterior structures and outdoor equipment components.
The material combines weather resistance with good impact performance. Molded parts can also achieve a high-gloss surface, making the material suitable for applications where structural integrity and visible appearance need to be considered together.
Typical applications include automotive luggage racks and photovoltaic-related parts.
Compared with materials mainly intended for indoor housings, weather-resistant PC/ASA places greater emphasis on external environment adaptability, impact resistance, and surface performance. It is suitable for relatively large or complex molded components with clear appearance requirements.
Performance for Impact and Molded Appearance
The typical density is 1.14 g/cm³, while molding shrinkage is 0.50%–0.70%.
Tensile strength at break is 42 MPa, and elongation at break is 28%. The material provides a flexural strength of 62 MPa and a flexural modulus of 1750 MPa.
Notched Izod impact strength reaches 50 kJ/m². The listed flame-retardant performance is UL-94 HB.
This performance profile gives Weather Resistant Polycarbonate ASA Blend a balance of weather resistance, impact performance, structural flexibility, and surface quality for suitable exterior components.
The available product information does not provide a heat deflection temperature. Therefore, projects with clearly defined high-temperature requirements should confirm the required thermal performance during material selection rather than assuming a specific value.
Large Exterior Parts Need Mold and Surface Evaluation
Automotive luggage racks can be relatively large and may include mounting holes, connection ribs, and curved visible surfaces. Buyers should consider loading method, wall thickness changes, and installation structures when selecting a material.
Photovoltaic-related components may involve outdoor installation, long-term fixing, and exposed surfaces. Material selection should therefore consider weather resistance together with impact performance and dimensional stability.
Before mass production, sample parts can be checked for flow marks, weld lines, shrinkage, and warpage on high-gloss surfaces.
Gate design, cooling conditions, and holding pressure may also influence the final appearance. Actual part samples provide a useful basis for confirming whether Weather Resistant Polycarbonate ASA Blend matches the required surface and assembly conditions.
Support for Appearance and Molding Requirements
Diyou New Material supplies modified materials covering weather-resistant, reinforced, flame-retardant, and impact-modified systems.
For weather-resistant PC/ASA, the technical team can support material selection according to part drawings, appearance standards, installation conditions, and molding requirements.
The company also has precision injection molding and post-processing capabilities that can be used to evaluate surface condition and assembly performance.
Raw materials, extrusion processing, and finished-product properties are managed through standardized production procedures. For customized development and batch purchasing, technical communication can focus on mold structure, surface condition, shrinkage, and actual application requirements.
