Physical and Chemical Properties:
Food grade poly-isobutylene is transparent and odorless semisolid.
Applications:
Chewing GumS: Poly-isobutylene can improve the gum quality when mixed with wax paraffin wax and resin; it can also make the gum more flexible and stable, maintaining good hydrophobic property and excellent film-forming property.
Food Binding Agent: mixed with various adhesives (including pressure sensitive adhesive), poly-isobutylene has the functions of adhesive bonding and modification.
Poly-isobutylene has a hydrophobic property and can keep low-toxicity absorption and high-temperature stability when mixed with hydrophobic substances (CMC, pectin, gel). It also adjustable in hardness and has germ resistance.
Food Packing: 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. Poly-isobutylene can improve the low-temperature stability and water resistance of product.
Food grade Hot Melt Adhesive: Poly-isobutylene has a function of plasticization, and can be used for thermal-plastic rubber, etc.
Medicine plaster: Food grade poly-isobutylene 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. With the properties, including non-irritability, repeated pulling and sticking, and non-hair collecting etc., food grade poly-isobutylene has developed into a leading material for medicine plasters.
