Applications                                                                                                                         1)Chewing Gums:polyisobutylene can improve the gum quality,it can also make the gum more flexable and stable,mataining good hydrophobic property and film-forming property.


2)Food Hot-melt Adhesive:polyisobutylene is blinded as a plasticizer of hot-melt adhesive for food,use thermoplastic rubber (TPR) and the like as the base.


3)Foodstuff Packaging Material:poly-isobutylene can be mixed with various paraffin waxes and high molecular polymers to serve as the releasing agent of packaging films, for example, polymer of poly-isobutylene and paraffin wax can be used as the packaging films for cheese.


4)Medical Plaster:polyisobutylene is now widely used in the field of medicine plaster.It has nice compatibility with both western medicines and traditional Chinese medicines,because of its unique net structure long chain and macro molecule. sticking,and non-hair collecting etc.,Food grade poly-isobutylene has developed into a leading material for medicine plasters.


5)Make-up grade polyisobutylene:the structure of make-up grade polyisobutylene is close to the alkane hydroxy of sebum, therefore its skin compatibility is very good.Non-toxic, tasteless, high purity,not easy to oxidize and emulsifies,with all of these characteristics,it can form the water resistance membrane, so the moisturizer is strong.The main application scope is the skin care frost, the lipstick, the cosmetics.Non contain of the chlorine,the purity is high, luminous, the moisturizer is good, it can be used as the substitution of spiny dogfish alkane.

Sealant, polyisobutylene can be used in sealants in double glazing windows and other applications for the construction industry.


6)Adhesives, polyisobutylene can be used in pressure sensitive, hot melt or solvent based adhesives.


7)Roofing: polyisobutylene can be used in roofing membranes, waterproofing for tunnels and cellars.


8)Lubricants, polyisobutylene can be used as additives to increase the viscosity for a variety of lubricants, including engine oils, gearbox oils, hydraulic fluids, and lubricating greases etc.


9)Paraffin and wax, polyisobutylene can be blended with paraffin wax and other waxes and used to coat or laminate paper.


10)Bitumen, polyisobutylene can be added to rubber to get higher melt viscosity and other characteristics.


11)Commercial pipes in underground or underwater locations, polyisobutylene can be used to provide self healing properties and to combat potential punctures, and to keep moisture away from the optical fibers.
