Ester Gum is a steam-stripped, glycerol ester of tall oil rosin. The process conditions of gum grade Ester Gum is tightly controlled to ensure a resin that meets the highest standards set forth by the Beverage industry for consistent good taste and low odor characteristics. Ester Gum has achieved the high quality once dominated by the gum grade resins made from wood rosin. This consistency and high quality is assured through a very special quality control screening.
Ester Gum is available in both solid and pastille (bead) forms. We recommend, however, that shipment of the resin be taken in the solid form, rather than the beaded form. This would reduce the possibility of the resin being oxidized, which could ultimately affect the taste and odor characteristics.

Primary Points Of Entry, Emergency And First Aid Measures:
Skin contact : If molten products contact the skin, apply cold water immediately. Obtain services of a physician immediately for burn treatment.
Special Precautions:Maintain good housekeeping to control dust accumulations.Dust Explosion Hazard Class II. Handling of material should be in a accordance with NEPA if handled with flammable or combustible materials, the explosion hazard may increase. Flaked material may cause a dusting problem.
Waste Disposal: Disposal must be made in accordance with applicable governmental regulations.
Control Measures:
If dust is generated, wear NIOSH approved dust respirator or dust mask. Avoid ignition sources. Local exhaust recommended when generating excessive levels of airborne dust or vapors when heating resin wear general work gloves Wear safety glasses when handling solid resin. Use eyes goggles covered with faceshield when handling hot molten resin.
