This week marks the debut of a redesigned resin pricing chart in Plastics News. The major goals of the changes that you see today are to make the chart more attractive and more informative for most of our readers, and to make better use of the space.
Some of the changes are obvious. We have added new graphics that will change every week and are designed to help explain the supply/demand picture. These may include prices for natural gas and crude oil, pricing histories for specific grades of resin and data related to current supply trends.
We've also created a new section devoted to plastics futures contracts traded on the London Metal Exchange.
These types of information will prove invaluable for anyone interested in current resin pricing - and in trying to predict where prices are moving.
Many of the other changes will be less apparent, unless you're looking for something and can't find it. So here is a list of some of the other changes:
* The category formerly called Volume Thermoplastics has been changed to Commodity Thermoplastics. However, most of the materials in this section have not changed.
* All the ABS grades have moved from the Engineering Thermoplastics section to Commodity Thermoplastics.
* Several specific grades of commodity thermoplastics have been dropped: LDPE - extrusion 2-4% EVA film; LDPE extrusion fractional melt; LLDPE - extrusion, fractional melt film; and PS - EPS, cups modified. Each of those materials is closely related to another material (or materials) that remain on the chart, so it will be easy to continue to follow those pricing by watching prices for the related grades.
* Several materials in the Engineering Thermoplastics section have been dropped: ABS - injection extra-high-impact; ABS plating; ABS structural foam; and PVC/ABS.
* Thermosets alkyd and diallyl phthalate have been dropped.
For many years, we have devoted space on our weekly charts to some materials that rarely change, or stay within a fairly wide range. In our new chart, some of those grades will appear once per month, instead of weekly. They include:
* All materials in the High-Temperature Thermoplastics section.
* All grades in the Thermoset section.
* The following materials from the Engineering Thermoplastics
