APAO ( Amorphous Poly Alpha Olefin ) is an amorphous co-polymer of propylene and ethylene or other alpha-olefin produced by special catalyst .

As bitumen modifier ( waterproofing membranes , road pavement...) , APAO shows :

1.Excellent high temperature property ;

2.Good low temperature flexibility ;

3.Good water resistance ;

4.Good anti-oxidation and UV stability ;

5.Superior compatibility with nearly all kinds of asphalts ;

6.Good compatibility with SBS , EVA , EPDM , PE , IPP ...

The above all features allow APAO to be used in modified bitumen waterproofing membranes( APP , SBS , EPDM , EVA types of waterproofing membranes ) . Meanwhile , APAO also could be used for road pavement and maintenance . The prominent high temperature property endow APAO a wide application in regions with hot weather .
