ACMO Monomer Application scenarios

1. Food Packaging
Enhances transparency and gloss for superior appearance; FDA-certified, safe and odorless.
Transparent meal containers, food storage containers, beverage cups, packaging bottles (e.g., juice/dairy bottles).

2. Medical Supplies
Improves material rigidity and heat deflection temperature, enabling products to withstand high-temperature steam sterilization.
Syringes, medical trays, infusion containers, etc.

3. Consumer Goods
Improves product aesthetics (high transparency, high gloss), enhances tactile feel and durability.
Cosmetic packaging boxes, transparent storage containers, household items.

4. Industrial & Specialty Packaging
Enhances film transparency and moisture resistance, or improves processing efficiency for thin-walled products.
Biaxially Oriented Polypropylene (BOPP) film, DVD/CD cases.

5. Emerging Field: Plastic Electronics
As a chemical additive, precisely controls crystallization processes in semiconductor polymer films to enhance device performance and manufacturing efficiency.
Flexible circuits, solar cells, organic light-emitting diodes (OLEDs), and other plastic electronic components.

🧪 Core Functions & Characteristics
Core Function: Acts as a “crystallization seed” by providing abundant nucleation sites during PP melt cooling, enabling finer and more uniform crystalline structures. This significantly reduces haze, enhances transparency, and simultaneously improves product rigidity, surface hardness, heat deflection temperature, and impact strength.

Processing Advantages: Elevates crystallization temperature to shorten molding cycles and boost production efficiency.

Safety & Environmental Compliance: Non-toxic and odorless, certified for food contact materials by FDA and other regulatory bodies.

Nucleating agent 3988 Usage

Mainly suitable for homopolymer and random copolymer polypropylene products and LLDPE film, can be directly blended with resin and can also be used for injection and extrusion molding.

 

Recommended dosage

It is recommended to add 0.2%-0.3% of 3988 to obtain the best performance, the specific amount of addition according to the actual needs of discretion.

Mixing and Dispersing

It is recommended to mix 3988 transparent agent and polypropylene powder/granule at high speed and then transfer to extruder feeder for extrusion pelletizing. A small amount of white mineral oil can be added to promote the dispersion of the transparent agent. Prevent uneven dispersion of the material. Transparency agent 3988 can also be prepared as a high concentration masterbatch and then diluted proportionally to the expected amount of the high concentration masterbatch.

Extrusion Pelletizing

A twin-screw extruder or a single-screw extruder with high mixing capacity is recommended for good dispersion to improve the permeability of 3988. Extrusion temperature is recommended to be above 230°C.
