Nucleating agent 3940 Application scenarios

1. Food and Daily Necessities Packaging
Enhances transparency and gloss for more aesthetically pleasing packaging; improves rigidity to facilitate thinner walls.
Food containers, beverage cups, transparent bowls/buckets/plates, microwaveable meal containers, stationery (e.g., CD cases), premium diningware.

2. Medical Packaging and Supplies
Meets transparency and hygiene safety requirements, suitable for high-temperature sterilized products.
Medical supplies, pharmaceutical packaging.

3. Films and Sheets
Significantly boost film transparency and gloss.
LLDPE films, PP cast films, thermoforming sheets, transparent tubing.

4. General-purpose plastic products
Enhances product rigidity, surface hardness, and heat deflection temperature while shortening molding cycles and boosting production efficiency.
Household items, industrial components, and various injection-molded or extruded products.

🛠️ Usage Instructions
Typical dosage: Recommended addition rate is 0.1%–0.3% by resin weight; optimal transparency enhancement is typically achieved at 0.2%.

Mixing Method: To ensure uniform dispersion, PP powder can be directly mixed during processing. For PP/PE pellets, it is recommended to first wet the pellets with a small amount of white oil (approximately 1.5-2.0 ml/kg), then add the nucleating agent powder and mix to achieve even coating.

Processing Methods: Can be directly compounded with resin. It is also commonly pre-formulated into high-concentration masterbatch (e.g., 2.5%-5%) for blending with standard resin, offering greater convenience and improved dispersion.

Process Compatibility: Suitable for various processing techniques including injection molding, blow molding, extrusion, and cast film production.
