We can now expedite our R&D efforts and produc- tion development by proving resin performance prior to customer trials. This is enabling us to produce attrac- tive options using new structures with reliable accuracy”, Niwat added. SCGChemicals, theparent companyof Thai Polyethylene, is one of Thailand’s largest integratedpetrochemical com- panies. The company offers products ranging fromupstreamproduction of ole fi ns to downstream production of polyethylene and polyvinyl chloride. The installation of the Davis-Standard lab line at their facility in Rayong, Thailand, aligns with the company’s commitment to developing new tech- nology that creates high value-added products (HVA) and service solutions for customers worldwide. Thai Polyethylene Co., Ltd.
