Chewing Gum Base Ester Gum
Chewing gum base ester gum is a glycerol-rosin ester that provides chew elasticity and flavor release in gum base formulations. Its water-insoluble nature maintains gum cohesion during mastication, making it a key ingredient in chewing gum production. This product falls under tariff item 3806.30.00 as an ester gum derived from rosin.
3806.30.00Food-Grade Ester Gum for Soft Drinks
Food-grade ester gum for soft drinks is typically glycerol or pentaerythritol rosin esters used to stabilize citrus oils in carbonated beverages. It prevents oil separation and enhances mouthfeel without affecting flavor, making it essential for beverage emulsion stability. This product is classified under tariff item 3806.30.00 as an ester gum.
3806.30.00Glycerol Ester of Wood Rosin (Food Grade)
Glycerol ester of wood rosin is a pale, tack-free resin approved as a food additive (E445) for beverages and confections. It functions as an emulsifier in citrus oil beverages and as a masticatory substance in chewing gum. This product falls under tariff item 3806.30.00 as an ester gum derived from rosin.
3806.30.00High-Softening Point Penta Rosin Ester
High-softening point pentaerythritol rosin ester (130-110°C ring & ball) provides heat resistance in tire cord adhesives and tape formulations. It is derived from disproportionated tall oil rosin for color stability and performance. This product is classified under tariff item 3806.30.00 as an ester gum.
3806.30.00Liquid Methyl Ester Gum for Printing Inks
Liquid methyl ester gum serves as a solvent-free plasticizer in lithographic and gravure printing inks. Its low viscosity enables high pigment loading without tack buildup, improving print quality. This product falls under tariff item 3806.30.00 as an ester gum derived from rosin.
3806.30.00Methyl Ester of Rosin (Methyl Rosinate)
Methyl ester of rosin, also known as methyl rosinate, is a low-viscosity liquid resin formed by esterifying rosin acids with methanol. It serves as a plasticizer in inks, coatings, and synthetic rubber compounds. This product is classified under tariff item 3806.30.00 as an ester gum.
3806.30.00Pentaerythritol Ester of Tall Oil Rosin
Pentaerythritol ester of tall oil rosin is a high-viscosity synthetic resin produced by esterifying tall oil rosin acids with pentaerythritol. It is widely used as a tackifier in adhesives, hot-melt glues, and pressure-sensitive tapes. This product falls under tariff item 3806.30.00 as an ester gum.
3806.30.00Triethylene Glycol Ester of Rosin
Triethylene glycol ester of rosin is a soft, tacky resin used in hot-melt adhesives and bookbinding glues. Its polyol esterification provides flexibility and low melt viscosity, making it ideal for bonding applications. This product is classified under tariff item 3806.30.00 as an ester gum.
