Shanghai Wenqin Plastics Co., Ltd., established in 2020, is a specialized manufacturer committed to providing high-performance engineering plastics. Our ASA Resin PW-978B High Impact Strength Grade is engineered specifically to meet the demanding requirements of outdoor applications, offering exceptional durability against environmental stressors. This product represents our dedication to quality and innovation, backed by a robust operational framework in Shanghai and a commitment to international standards.
ASA (Acrylonitrile Styrene Acrylate) PW-978B is a thermoplastic polymer renowned for its superior balance of properties, making it an ideal choice for components exposed to harsh outdoor conditions. Unlike standard ABS, ASA incorporates an acrylate rubber component, which significantly enhances its resistance to ultraviolet (UV) radiation, weathering, and chemical exposure while maintaining high mechanical strength.
- Superior Weathering Resistance: The acrylate component provides outstanding UV stability, preventing yellowing, fading, and degradation of mechanical properties over prolonged sun exposure.
- High Impact Strength: The PW-978B grade is formulated to deliver excellent toughness and impact resistance, even at low temperatures, ensuring product integrity in varying climates.
- Good Chemical Resistance: Resists attack from many common chemicals, greases, and cleaning agents, maintaining surface quality and functionality.
- Thermal Stability: Maintains performance across a wide temperature range, suitable for applications experiencing thermal cycling.
- Ease of Processing: Compatible with standard injection molding and extrusion equipment, facilitating efficient manufacturing with good flow characteristics.
- Color Consistency: Offers excellent colorability and long-term color retention, crucial for aesthetic outdoor products.
The technical specifications of ASA Resin PW-978B are tailored to ensure reliability in outdoor settings. Below is a summary of key properties:
| Property | Test Method | Typical Value | Unit |
|---|---|---|---|
| Tensile Strength | ISO 527 | 55 | MPa |
| Flexural Modulus | ISO 178 | 2400 | MPa |
| Notched Izod Impact Strength | ISO 180/A | 25 | kJ/m² |
| Melting Point (Vicat) | ISO 306 (B50) | 105 | °C |
| Melt Flow Rate (MFR) | ISO 1133 (220°C, 10kg) | 15 | g/10min |
| Specific Gravity | ISO 1183 | 1.07 | - |

Frequently Asked Questions (FAQ)
Q1: What are the main differences between ASA and ABS resins?
ASA offers significantly better UV and weathering resistance compared to ABS due to its acrylate component. ASA retains its color and mechanical properties outdoors, whereas ABS tends to degrade.
Q2: Is ASA Resin PW-978B suitable for automotive exterior parts?
Yes, its high impact strength and excellent weathering resistance make it a suitable candidate for non-structural automotive exterior trim components, grilles, or mirror housings.
Q3: Can this material be used in injection molding for thin-walled parts?
Yes. The melt flow rate and processing characteristics of PW-978B are designed for efficient injection molding, including applications with thinner wall sections.
Q4: What is the typical color range available?
Standard colors are available, and custom colors can be developed upon request to match specific design requirements.
Q5: Does it require any special storage conditions?
It should be stored in a dry, cool environment away from direct sunlight. Standard polymer storage practices are recommended.
Q6: Are there any regulatory certifications specific to this product?
The resin is produced under a quality system certified to ISO9001. Specific end-product certifications depend on the final application and should be verified by the manufacturer.
Q7: What is the packaging format?
The standard packaging is 25kg bags. Other packaging options (e.g., bulk bags, drums) can be arranged based on order volume and customer needs.
Q8: How does the impact strength perform at low temperatures?
ASA PW-978B maintains good impact resistance at lower temperatures, making it suitable for outdoor applications in colder climates.
