Internal And External Lubricants : Acid Esters & Glyceryl Monostearate GMS For PVC

Description:

Distilled Glycerin Monostearate(DMG90), also called distilled Monoglycerides or Glycerin Monostearate GMS99, is made with natural vegetable oil and fat, which is the most widely applied for food emulsifier.

CAS No.:31566-31-1

MF:C21H42O4

EINECS No.: 204-664-4 

LUBRICANT CLASSIFICATION for PVC terminology:

. External = Insoluble

   .Typically provide lubrication between the polymer and the metal surface of the processing equipment

   .Classic types: Polyethylene waxes, Oxidized Polyethylene waxes, Paraffins, Metal Soaps, Esters (high esterification), Amides, Fatty Acids.

    like Acid Esters - Pentaerythritol Stearate PETS

. Internal = Semi-Soluble (Plasticizer)

  .Typically reduce bulk viscosity through partial compatibility with the polymer, thus opening the polymer chain with the lubricant’s soluble component while providing intermolecular lubrication with the less soluble portion of the molecule. 

  . Classic types: Fatty alcohols, Esters (low esterification), EVA Wax, others.

   like Acid Esters - Glyceryl Monostearate GMS
