Putting it to the test - polymer analysis in the laboratory
Research and development and quality control rely heavily on accurate analytical measurements. Now identifying recycled materials and verifying compliance for increasingly stringent regulations are also proving just as important areas for polymer analysis. Jennifer Markarian reports on some of the major issues in analytical techniques in the laboratory.

Cost reductions drive developments in auxiliary equipment
To no one's surprise, a primary concern for plastics processors is reducing costs related to high energy and resin prices. In addition to reducing energy use, processors are concerned about reducing resin waste from spills, contamination, or damage during processing that results from improperly dried materials. Research and development in dryers and conveying systems is focusing on meeting these customer needs. Jennifer Markarian reports.

Dosing and blending - getting the right mix
Accurate and repeatable dosing and blending is crucial in the manufacture of compounds and masterbatches. A wide variety of equipment is available to ensure that extruders run efficiently. Jennifer Markarian outlines some of the systems on offer from machinery suppliers.
