Ester Introduction

Ester lubricants are polymer-processing additives built around ester functionality. Different molecular structures and esterification levels provide distinct compatibility, lubrication, melt-flow and release characteristics, allowing ester lubricants to meet the requirements of PVC, transparent products and high-performance engineering plastics.

Key Features

Ester Structure & Compatibility

Different acid, alcohol and esterification structures create different polarity and polymer interactions, allowing ester lubricants to be selected for specific processing systems.
Lubrication & Melt Flow

Ester lubricants reduce friction within polymer melts and help regulate melt flow, supporting smoother processing and a balanced lubrication profile.
Release & Surface Quality

Selected ester structures provide effective release and reduce adhesion during processing, supporting easier demolding and good finished-surface quality.
Thermal & Processing Performance

Molecular structure determines volatility and thermal behavior, allowing selected ester lubricants to meet both conventional PVC processing and demanding high-temperature applications.

Applications Advanced additive solutions for diverse polymer applications

Rigid PVC

Ester lubricants provide controlled internal lubrication and melt-flow adjustment in profiles, pipes, fittings, sheets and other rigid PVC products.

Transparent Products

Selected ester lubricants combine good compatibility with lubrication and release, supporting stable processing, surface quality and optical appearance in transparency-sensitive applications.
