Shanghai Wenqin Plastics Co., Ltd., established in 2020, is a specialized manufacturer of high-performance engineering plastics. We proudly introduce our ASA Resin PW-997S, an injection molding grade material engineered to deliver an exceptional surface finish that meets the demanding aesthetic and functional requirements of modern manufacturing. Our commitment to quality is reflected in our adherence to stringent management systems, ensuring that every batch of PW-997S provides consistent performance and reliability for our global clientele across diverse markets.
This product is designed for applications where visual appeal is as critical as structural integrity. The superior surface quality reduces or eliminates the need for post-processing, saving time and costs while enhancing the final product's value. Below, we detail the characteristics, technical specifications, and advantages of PW-997S.
Core Characteristics & Advantages:
- Excellent Surface Finish: Produces high-gloss, smooth surfaces directly from the mold, minimizing painting or polishing.
- Enhanced Weather Resistance: ASA resin inherently offers superior resistance to UV radiation, heat, and environmental stress cracking compared to ABS.
- Good Mechanical Properties: Provides a balanced combination of impact strength, rigidity, and heat deflection temperature suitable for exterior applications.
- Ease of Processing: Specifically formulated for injection molding, ensuring stable flow, fast cycle times, and excellent mold release.
- Color Consistency: Offers excellent pigmentability and color stability, maintaining its appearance over time even under outdoor conditions.

Frequently Asked Questions (FAQ):
-
What is the main advantage of ASA over ABS?
ASA offers significantly better resistance to ultraviolet (UV) light and weathering without requiring additives, making it suitable for long-term outdoor use where ABS would degrade and yellow. -
Can PW-997S be used for automotive exterior parts?
Yes, its combination of good mechanical strength, heat resistance, UV stability, and excellent surface finish makes it a suitable candidate for automotive trim, grilles, and mirror housings. -
What injection molding parameters are recommended?
Typical melt temperature ranges from 220-250°C, with mold temperatures between 50-80°C. Drying before processing (e.g., 2-4 hours at 80-90°C) is recommended for optimal results. -
Is the material available in colors?
Yes, PW-997S can be supplied in a wide range of standard and custom colors. Its excellent pigmentability ensures vibrant and consistent coloration. -
Does it have any relevant industry certifications?
While the material itself may not carry specific end-product certifications, our manufacturing processes are certified under ISO9001 and ISO14001, ensuring controlled and reliable production. -
What is the typical lead time for orders?
Lead times depend on order quantity and color requirements. Generally, standard colors are available from stock or with short lead times. Please contact us for a specific timeline. -
Can you provide technical data sheets and samples?
Yes, we can provide comprehensive technical data sheets and material samples for evaluation upon request to support your qualification process. -
What packaging is used for shipment?
The resin is typically packaged in 25 kg moisture-proof bags on pallets, ensuring safe and clean delivery to your facility.
