Irgatec® CR 76 IC

Technical Datasheet | Supplied by BASF
Irgatec® CR 76 IC by BASF is a sterically hindered hydroxylamine ester in a polymer matrix. It is a novel, peroxide free polymer modifier for polypropylene. It allows a controlled degradation of polypropylene during processing leading to a narrow molecular weight distribution. It is characterized by a low content of volatiles. It is highly efficient at extrusion temperatures exceeding 250°C and therefore particularly suited for polypropylene meltblown applications. Irgatec® CR 76 IC is available as a pre-dispersed concentrate, which guaranties a homogeneous distribution during extrusion. Polypropylene meltblown nonwovens produced with Irgatec® CR 76 IC exhibit higher hydrostatic height, improved air permeability as well as higher long-term thermal stability. The mechanical properties such as tenacity and elongation are also improved. Typical concentrations for the production of polypropylene melt blown nonwovens are between 1-2%, for processing temperature exceeding 250°C. For spunbond PP, the recommended concentration of Irgatec® CR 76 IC is between 0.5 and 1%.
