Ningbo Formosa AS NX3400 is a high-performance Styrene Acrylonitrile (AS/SAN) copolymer produced by the global petrochemical giant Ningbo Formosa. As a premium thermoplastic engineering plastic, NX3400 is highly regarded in the industry for its excellent optical clarity and balanced mechanical properties.
The physical appearance of this material is uniform, high-transparency granules (pellets). Due to the optimized acrylonitrile content in its molecular structure, NX3400 offers stronger chemical resistance and toughness than standard polystyrene while maintaining transparency. It is particularly suitable for industrial manufacturing sectors with dual requirements for aesthetics and durability, making it the preferred material for lighting fixtures and high-end consumer electronics housings.

Excellent Optical Transparency: NX3400 features high light transmittance and extremely low haze, making it a perfect substitute for certain expensive transparent materials.
Superior Chemical Resistance: Compared to common transparent plastics, it has stronger resistance to kitchen oils, detergents, and various chemical solvents.
Outstanding Dimensional Stability: This grade offers low and uniform shrinkage, ensuring precise dimensions and shape stability of parts after injection molding.
High Rigidity and Strength: It possesses high tensile strength and flexural modulus, capable of withstanding specific structural loads.
Good Processability: With an MFR of 1.1g/10 min, it is suitable for injection molding of large or complex structures, providing a high-gloss surface finish on the end product.
Due to its balance of aesthetics and utility, AS NX3400 is widely used in the following fields:
Lighting Fixtures: Manufacturing of lampshades, diffusers, and various transparent lighting housings, especially suitable for environments with prolonged light exposure.
Household Appliances: Internal refrigerator components (such as drawers and trays), blender jars, and transparent dust containers for vacuum cleaners.
Cosmetic Packaging: High-end perfume bottle caps, cream jars, and makeup cases, utilizing its high transparency and chemical resistance to prevent stress cracking.
Consumer Electronics: Instrument panel covers, calculator keys, and transparent electronic enclosures.
Kitchenware: Seasoning jars, salad bowls, and other food-contact (subject to relevant grades) transparent containers.
Yes. While AS has lower hygroscopicity than nylon, it is recommended to dry the granules at 80°C – 85°C for 2-3 hours before injection molding to ensure the product surface is free of silver streaks or bubbles.
Compared to PMMA, NX3400 offers better chemical resistance and lower costs. Compared to PC, although its impact strength is slightly lower, it provides better processing fluidity and more competitive pricing, making it a more cost-effective transparent solution for scenarios that do not require extreme heat resistance or high impact strength.
Ningbo Formosa AS NX3400 generally complies with the RoHS environmental directive. Regarding specific UL flame retardant ratings or food contact certifications (such as FDA/GB standards), as requirements vary by application, we recommend contacting our technical team for the latest compliance documentation.
