Some of the information arises from laboratory work with small-scale equipment which may not provide a reliable indication of performance or properties obtained or obtainable on larger-scale equipment. UV Resistance Test - 0.68W/m2 @ 45°C expose 168 hours Anti-abrasion Test - H18 wheel load 1kg @ 500 cycles Surface/Non-blooming - Visual observation Touch Feel - Hand touch Mechanical Properties - Refer to hardness, gravity, tensile strength, elongation, MFI, and flexural modulus, which are tested using ASTM methods Processing - Demold speed & cycle time TEST RESULTS Comprehensively, the Versaflex CE 3130 non-blooming series performed better than competitive materials in balancing functional properties and processing.

At every stage of the plastic life cycle, from manufacturing through processing and end use, Cesa Nox antioxidant masterbatches help maintain shine and transparency while preventing yellowing, surface cracking and odors.

Key considerations should include addition ratio, screw design, extrusion or cycle speed and other factors, such as wall thickness and part design. 

Maxxam™  Polyolefin Formulations solution exceeded performance requirements, eliminated overmolding, and reduced cycle times.
