Irgaclear DM
Diparamethyldibenzylidene sorbitol
54686=97-4/81541-12-0
* Application:
Irgaclear DM is a highly effective clarifier for polypropylene homopolymer and random copolymer.
* Features:
Irgaclear DM is used for producing high clarity polypropylene. The product acts as a nucleating agent, by creating a large number of smell size spherulites(< 1 micron): during the cooling of the polypropylene melt. These small spherulites lead to a polypropylene that has greatly improved clarity and reduced haze compared to polypropylene which is not clarified. The elastic modulus of the polymer is also enhanced by using Irgaclear DM.
