A big polyethylene expansion in Texas from Chevron Phillips is featured in this week’s Material Insights video. Chevron Phillips plans to build two new ethylene units with combined annual capacity of more than 2 billion pounds. The $5 billion project which also includes a new ethylene unit is expected to create 400 permanent jobs and as many as 10,000 temporary engineering and construction jobs. Recent price decreases in North American prices for solid polystyrene and PET bottle resin also are covered in this week’s video. The video wraps up with a prediction of a stronger year in 2012 for the North American PE market. That prediction comes from Dow Chemical executive Mauro Gregorio, who told Plastics News that both volume and margins could improve for PE in 2012, with the packaging market playing a major role in that comeback.
