POLYMER ADDITIVES
APPLICATION DEFINITIONS :

Lubricant- Additives used to improve flow characteristics of polymers. Depending upon compatibility in a polymer, these materials can function internally or externally. Internal lubricants reduce melt viscocity, which promotes flow. External lubricants reduce friction between the polymer melt and the metal surfaces of the processing equipment. Injection moulding,external lubricants are referred to as internal mould release additives. A balance of internal and external lubrication leads to increased production rates and/or reduced energy.

Processing Aid- Multifunctional additive to enhance flow and to improve dispersion of fillers in processing filled polymer compounds.

Antistatic Agent- Additive migrate to the surface to dissipate static charge through association with moisture in the air.

Slip Additive- Inhibits polymer film from sticking to itself and other surfaces such as converting equipment.

Dispersion Aid- Aids in the uniform dispersion of additives such as pigments in colour concentrate formulations.

Viscocity Depressant- Additive, having good compatibility with PVC, to reduce the viscocity of PVC paste used for application like Coating, Dip-moulding etc.

Antifog Agent-Additive migrates to the polymer surface to prevent the formation of visible condensation. It is designed to have a controlled solubility in order to provide a reservoir of material that continuously migrates to, and is lost at the surface.
