How much could get improved for the plastic performance by adding impact modifier

What are the main important properties for plastics ? How much could get improved for the plastic performance by adding impact modifier

Answer :  

Plastics main properties including Mechanical Property , Optical Property, Electrical Property, Physical Property, Thermal Property, Aging Property .

Among which Mechanical Property is the most important, it contains : Tensile Strength  , Notch Impact Strength, Flexural Strength, Shore Hardness,

Rockwell Hardness. These items are all what we must test after adding our plastic impact modifiers. In Our Test ,by adding our plastic impact modifiers, the plastic properties get increased to nearly 95% of the New plastic materials.
