Masterbatch is a concentrated mixture of pigments and/or additives encapsulated during a heat process into a carrier resin which is then cooled and cut into a granular shape. Masterbatch allows the processor to colour raw polymer economically during the plastics manufacturing process.

Ester's Masterbatches are polymer concentrates which contain functional additives that enhance functioning of virgin or recycled materials by blending.

Our Masterbatches are proof of technological excellence which is well supported by creative resources and unparalleled services. The additive concentrates and performance solutions for plastics which we produce have made Ester a preferred supplier across the industry.

Ester's Masterbatches as Specialty Polymers are named after ESPET MB with their respective codes. ESPET MB grades can be blended in minimal quantities as required with other materials like PET/ Recycled PET/ Poly Amides. It is done so to improve characteristics of conventional materials mainly in Carpets, textile, and Technical Yarn industry.

As functional Masterbatches, ESPET MB assists to make the blend miscible or reactive to attain a better product with requisite elements. These are customizable as processed through SSP technology.

The unmatched quality and value of our product with an unsurpassed commitment towards environmental security and health, has made us the market leader.
