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

Advantages of APAO are shown as follows :

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 .

As component in sealant:

APAO has good solubility with PIB ( polyisobutene )or butyl rubber . Adding APAO in the formulation helps to improve processing property of PIB base sealant , improve the aging resistance and high / low temperature property , as well as achiving a better shape , better looking and superior moisture resistance.

In hotmelt adhesive , APAO exhibits / is :

1.Good adhesiveness to PP , PE , paper , metal and soon ;

2.High temperature resistance ;

3.Excellent electric and non-corrosive properties ;

4.Good compatibility with SBS , EVA , and tackifier ;

5.Solvent free and odorless ;

6.Clean and environment-friendly;

7.Cost efficiency;

8.APAO based hotmelt adhesive works in high moisture environments .

It's a very promising material for various industries .
