DMDBS CAS 135861-56-2 is an efficient nucleating agent widely used as polypropylene masterbatch additive. It can accelerate the crystallization rate of PP resin, shorten molding cycle, improve product transparency and surface gloss. With good dispersion performance, it is easy to formulate into masterbatch, suitable for various injection and extrusion polypropylene products.

Product Detail

CAS 135861-56-2 DMDBS Nucleating Agent Polypropylene Masterbatch Additive Accelerate Crystallization

Product Overview

DMDBS CAS 135861-56-2 is a high-efficiency sorbitol-based nucleating agent, ideal additive for polypropylene masterbatch. It effectively accelerates PP crystallization speed, shortens molding cycle and lifts production efficiency. Meanwhile, it reduces haze, improves transparency and surface gloss of finished products. The powder owns excellent dispersibility, convenient for masterbatch compounding, and adapts to various injection and extrusion PP processing scenarios.

Main Advantages

Accelerate polypropylene crystallization and shorten molding cycle

Boost production efficiency and lower manufacturing costs

Improve PP transparency and enhance surface gloss

Excellent dispersibility, easy to produce PP masterbatch

Good thermal stability under common molding temperatures

Wide compatibility with homopolymer and random copolymer PP

Basic Information

Chemical Name: Bis(3,4-Dimethylbenzylidene) Sorbitol

CAS No.: 135861-56-2

Alias: DMDBS

Appearance: White fine powder
