Shanghai Wenqin Plastics Co., Ltd., established in 2020, is dedicated to providing high-performance polymer solutions for the global market. Our ASA Resin PW-957 BK High Gloss Grade is engineered specifically for the demanding requirements of consumer electronics housing. This material combines exceptional aesthetic appeal with robust mechanical properties, offering manufacturers a reliable and visually superior solution for their premium product casings.
The core value of PW-957 lies in its ability to deliver a flawless, high-gloss finish directly out of the mold, significantly reducing or eliminating the need for secondary painting processes. This not only enhances production efficiency but also contributes to more sustainable manufacturing by lowering VOC emissions and energy consumption.
Detailed Product Features & Specifications:
This ASA resin grade is formulated to excel in applications where both appearance and durability are critical. Below are its key characteristics and advantages:
- Superior Aesthetics: Provides a deep, rich black color with a consistent high-gloss surface, ideal for premium consumer devices.
- Excellent Weathering Resistance: ASA polymer inherently offers outstanding resistance to UV radiation, heat, and moisture, preventing yellowing, fading, or brittleness over time.
- High Impact Strength: Maintains good toughness and impact resistance even at lower temperatures, ensuring the housing can withstand accidental drops and daily wear.
- Good Chemical Resistance: Resists common household chemicals, cleaners, and sweat, preserving the appearance and integrity of the housing.
- Excellent Processability: Designed for smooth injection molding with good flow properties, allowing for the production of complex, thin-walled designs with high surface quality.
- Dimensional Stability: Exhibits low shrinkage and warpage, ensuring precise part dimensions and assembly fit.

Frequently Asked Questions (FAQ):
Q1: What is the main advantage of ASA over ABS for electronics housing?
A1: ASA offers significantly better resistance to ultraviolet (UV) light and weathering compared to standard ABS. This prevents yellowing and degradation when the device is used outdoors or near windows, making ASA a preferred choice for long-term color stability.
Q2: Does the high-gloss finish require any special mold surface treatment?
A2: To achieve the optimal high-gloss result, it is recommended to use molds with a high-polish surface finish (e.g., SPI A1 or better). The resin itself is formulated to replicate the mold surface faithfully.
Q3: Can PW-957 be used for thin-wall applications common in modern devices?
A3: Yes, its good melt flow characteristics make it suitable for molding thin-walled sections while maintaining surface quality and adequate strength.
Q4: Is this material flame retardant?
A4: The standard PW-957 grade is not inherently flame retardant. However, flame-retardant (FR) grades can be developed upon request to meet specific safety standards such as UL94.
Q5: What are the recommended drying conditions before processing?
A5: Typical drying conditions are 80-85°C (176-185°F) for 2-4 hours. Proper drying is essential to prevent surface defects and ensure optimal properties.
Q6: Can colors other than black be provided?
A6: Absolutely. While PW-957 BK is a standard deep black high-gloss grade, we offer custom color matching services to produce this ASA resin in virtually any color required for your design.
Q7: How does it perform in terms of chemical resistance against common agents?
A7: ASA resin generally shows good resistance to diluted acids, alkalis, and aliphatic hydrocarbons. It offers better resistance to environmental stress cracking than some other thermoplastics when in contact with certain oils and greases.
Q8: What is the typical lead time for an order?
A8: Lead times depend on order quantity and destination. For standard grades and container loads shipped from Shanghai or Ningbo, typical lead times range from 2 to 4 weeks. We provide precise timelines upon receipt of your inquiry.
