NUCLEATING AGENT 3988 – CLARIFYING AGENT

(Sorbitol-Based Clarifying / Nucleating Agent 3988)

Chemical Name: 1,3:2,4-bis(3,4-dimethylbenzylidene) sorbitol
CAS No.: 135861-56-2

Product Description

Nucleating Agent 3988 is a high-performance sorbitol-based clarifying and nucleating agent, primarily designed for polypropylene (PP) and selected polyolefin applications.
The product significantly improves optical clarity, transparency, stiffness, and surface gloss of plastic products, while maintaining color stability and mechanical properties.

Nucleating Agent 3988 also accelerates crystallization, helping to reduce cooling cycle time and increase production efficiency.

Key Features

• Enhances transparency and surface gloss of PP products

• Shortens cooling cycle and improves processing efficiency

• Improves stiffness, flexural modulus, and heat resistance

• Odorless and suitable for food-contact and packaging applications

• Excellent thermal stability and compatibility with PP homopolymer, random copolymer, and impact copolymer

Applications

• Transparent PP products: food containers, cups, lids, packaging

• PP films, sheets, bottles, and transparent molded parts

• Household products, medical applications, and food packaging requiring high clarity

Recommended Dosage

• 0.2 – 0.3% by weight of polymer
  (Depending on polymer type and desired clarity level)
