Dimethyldibenzylidene sorbitol

Dimethyldibenzylidene sorbitol (CAS 135861-56-2), commercially recognized as Millad 3988, is a high-performance nucleating and clarifying agent used in polypropylene processing. It accelerates crystallization during molding and significantly improves optical clarity in finished plastic parts.

In polypropylene packaging and consumer goods, it enables processors to achieve glass-like transparency without switching to more expensive resins. Injection-molded food containers, caps, and closures benefit from faster cycle times.

Improved stiffness-to-weight ratios are achieved when this clarifier is incorporated at low loading levels. Thin-wall packaging films and sheets processed on high-speed lines use it to maintain consistent clarity across production runs.

In building and construction applications, it supports the production of transparent or translucent polypropylene components. This is essential where optical performance and structural integrity must both be met during the manufacturing process.

Dimethyldibenzylidene sorbitol is supplied as a fine white powder, suited for dry blending or masterbatch incorporation into polyolefin systems. It is available in food-contact compliant grades for various industries.

The material meets regulatory requirements for packaging applications in major markets. Technical-grade material is also available for non-food industrial applications where regulatory compliance is not a primary sourcing criterion.
