Ningbo Formosa AS NF2200 SAN Resin Raw Material

Ningbo Formosa AS NF2200 SAN Resin Raw Material (hereinafter referred to as NF2200 SAN Resin) is a high-performance, injection-molding grade Styrene-Acrylonitrile copolymer (SAN resin) introduced by the Ningbo Formosa brand. As a premium general-purpose transparent engineering plastic, it combines exceptional transparency, mechanical strength, and processing flowability, making it widely suitable for injection molding needs in transparent products, electronics, and packaging containers.

Zijun Plastics, as a professional manufacturer and supplier with years of experience in the engineering plastics field, provides authentic NF2200 SAN resin with a stable supply and comprehensive technical support.

Core Value Propositions

• High Transparency: Featuring high light transmittance and low haze with a flawless surface finish, it can be used directly for transparent product manufacturing without additional modification.

• Excellent Processing Flowability: Its moderate melt flow rate ensures smooth injection molding, preventing defects such as short shots or weld lines, and is highly suitable for mass production of thin-walled and complex transparent parts.

• Stable and Controllable Quality: Produced using advanced polymerization processes, it offers minimal batch variation and stable mechanical strength, ensuring standardized scale production and reducing production losses.

Common Application Areas

1. Transparent Products: Utilizing its high transmittance and low haze, it is used for cosmetic bottles (essence and lotion bottles), transparent stationery (pen holders, folder panels), transparent toy accessories, and instrument housings (small detector covers).

2. Electronic and Electrical Accessories: Suitable for high-end transparent or translucent components such as router shells, Bluetooth speaker covers, headphone charging case lids, and smart home control switch buttons.

3. Packaging Containers: Applied in high-end packaging like food boxes (biscuit and candy boxes), pharmaceutical bottles (capsule and tablet bottles), and daily necessity containers. Specific batches meet FDA standards for direct food and drug contact.

Processing Guidelines

1. Pre-treatment (Drying)

• Drying Temperature: 75-85°C.

• Drying Time: 2-3 hours (dehumidifying dryers are recommended to prevent surface defects like bubbles or silver streaks).

• Drying Standard: Moisture content must be ≤ 0.1% to avoid surface depressions and loss of transparency.

• Note: Dried material should be sealed and used immediately. Re-drying is required if the material re-absorbs moisture.

2. Processing Precautions

• Temperature Control: Processing temperatures should not exceed 220°C to prevent material degradation, yellowing, brittleness, and decreased transparency.

• Mold Maintenance: Clean the mold and nozzle every 6-8 hours to prevent material carbonization and maintain surface gloss.

• Cooling Treatment: After molding, natural or air cooling for 3-5 minutes is recommended to prevent deformation.

• Contamination Prevention: Avoid mixing with other resins. Use specialized SAN cleaning agents to thoroughly clean the barrel and nozzle when switching materials.

• Defect Adjustment: For weld lines, consider increasing injection temperature or speed, adjusting gate positions, and ensuring proper drying.
