II. Flagship Exhibited Product: Pushing NF-331 Medium & Low-Temperature Fluorine-Free Oil Repellent
In response to the fluorine-free oil-repellent demand of paper-plastic food container producers, Puxin independently developed Pushing NF-331, which precisely meets the market’s urgent need for eco-friendly, efficient and low-cost oil-repellent solutions, making it a preferred additive for food container manufacturers.
(1) Core Technical Advantages
- Independent R&D & Patented Formula
Pushing NF-331 features a complete formulation system, fully developed in-house with controllable core technologies.
- Automated Manufacturing
The whole production process — from raw material monomer treatment to finished product delivery — adopts automated lines, ensuring stable batch quality and avoiding inconsistencies.
(2) Key Product Features
- Medium & Low-Temperature Oil Repellency
Effective within 5–60°C, especially suitable for refrigerated storage below 20°C.
Tested: salad oil at 4–6°C placed in treated containers shows no leakage after 30 minutes at constant temperature.
- Stable Performance & Easy Storage
No special packaging required; can be stored exposed to air for a long time with minimal performance degradation.
Severe testing: products exposed to air at 45°C for 28 days + room temperature for 14 days still show no oil leakage at 55°C and 5°C.
- High Cost Performance
Direct control from raw material synthesis, eliminating intermediate links, reducing procurement costs for downstream customers while ensuring quality.
