Nucleating agents are mostly used within PP and they offer many benefits such as reduced cycle time during injection moulding, improved mechanical properties, improved dimensional stability, increased heat deflection temperature (HDT) and in some cases improved optical properties.
Norner offers several tests, the tests are performed in PP random copolymer and/or PP homopolymer.
Melting point and freezing point by DSC
Crystallisation speed by DSC (isothermal crystallisation half time)
Mechanical properties of injection moulded test specimens (E-modulus, charpy impact, HDT)
Haze on injection moulded samples (1- and 2-mm thickness)
