Medium Molecular Weight Polyisobutylene
(Food Grade)
Grade: HRDF-350 - HRDF-950
Mv:35, 000-100, 000
Physical and Chemical Properties:
The product is a kind of yellowish transparent semi-solid substance, nontoxic and odorless. It has good chemical stability and resistance to heat, ozone, acid and alkali, UV ray, and weather, etc. It has high electric volume resistance, low expansion coefficient, no dielectric medium, excellent electrical insulation no residues after pyrolysis, and good compatibility with polyethylene and paraffin wax, etc. It is soluble in organic solvents such as gasoline and benzene etc., but not in water and alcohol type solvents, and has good shearing stability.
Main 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.
