Polymer Industry Overview Polymers are a class of organic materials that are generally produced by converting natural gas or crude oil derivatives into monomers, such as ethylene, propylene, vinyl chloride and styrene. Our colorant and additives masterbatches are used in a broad range of polymers, including those used in food and medical packaging, transportation, building products, pipe and wire and cable markets. Our colorant and additives masterbatches are used in a broad range of plastics, including those used in food and medical packaging, transportation, building products, pipe and wire and cable markets.

Polymers are a class of organic materials that are generally produced by converting natural gas or crude oil derivatives into monomers, such as ethylene, propylene, and styrene. The ongoing conflict between Russia and Ukraine has impacted global energy markets, particularly in Europe, leading to high volatility and increasing prices for crude oil, natural gas and other energy supplies. Moh worked for Clariant AG (a global manufacturer of color and additives masterbatch) in various roles of increasing responsibility, culminating in a commercial leadership role in Southeast Asia.
