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.
