Plastics Technology: Resin Prices "Shoot Up"

In the February 2013 issue of Plastics Technology, senior editor Lilli Manolis Sherman reports that commodity resin prices have shot up for a number of reasons: unplanned disruptions in polymer feedstock production in December, planned cracker outages slated for the first four months of this year, etc. Monomer and resin prices have risen, especially with regards to polypropylene. Polyethylene and PVC have also been affected. Some geosynthetics manufacturers have acknowledged these price shocks too in having to increase prices on products as well. Learn more here.;
