Chewing gum is a soft, cohesive substance intended for chewing but not swallowing. Gum base is the non-nutritive, non-digestible, water-insoluble masticatory delivery system used to carry butyl rubber, sweeteners, flavors and any other substances in chewing gum and bubble gum. It provides all the basic textural and masticatory properties of gum. Gum bases for chewing gum are different from those for bubble gum. A bubble gum base is formulated with the ability to blow bubbles; it contains higher levels of elastomers or higher molecular weight polymers for this purpose. Gum bases for non-acid flavored gum use calcium carbonate as a filler, while gum bases for acid flavored gum use talc as a filler, since acids can react with calcium carbonate to produce a gas, which is undesirable. Bubble gum usually contains 15-20% gum base, while chewing gum contains 20-25% gum base and sugar-free chewing gum contains 25-30% gum base. Butyl rubber provides the elasticity or bounce in gum base and/or chewing gum. Cenway food grade butyl rubber IIR 532F is especially for the food industry which is strictly controlled under the global recognized HACCP food production management system.
Because of its low permeability, flavor is retained longer than with natural rubber-based products and thetransmission of air and waterr are minimized. Its low-temperature flexibility prevents it from becoming brittle and shattering,even in heavily filled compound. Butyl rubber has outstanding stability and resistance to ageing that can resists hardening during shelf storage, thus helps retaining the soft texture required for stick gums. It also serves as a hydrophobic pasticizer, providing softness and smoothness to enhance chewing.
