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

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 .
