• Product description :

  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 polymer modifier / component in masterbatch:

  1.APAO shows good compatibility with PE , PP , PIB , EPDM rubber , butylrubber , SBS , EVA and so on;

  2.APAO shows good tackiness and good fluidity;

  3.APAO works as a carrier replacing most of the PP , PE , PE wax used in masterbatch production;

  4.The end product has good shape and excellent processing property as well as toughness in stead of being brittle like when wax is used . Good wetting property with powder allows a high filling rate of over 80% .

  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 .

  APAO is also suitable for various applications like :

  •cablefillingcompounds ;

  •coating compounds for carpet tiles ;

  •carmats ;

  •papercoating ;

  •lamination...

  It's a very promising material for various industries .
