Generally, plastics are the preferred raw material for the manufacture of parts because of their ease of fabrication and their relative light weight. These attributes translate into excellent economics. However, occasional problems arise resulting in plastic part failure. The failure can result in significant property damage or injury. When failures occur, Plastic Expert Group becomes involved to conduct testing and analyses of the failed parts to determine the root cause of failure.
ROOT CAUSES OF PLASTIC PART FAILURE
We have found that plastic part failures are generally due to one of the following reasons:
Improper selection of material for the application
Manufacturing defects in the plastic raw material
Fabrication defects in the plastic part
Poor part design
Improper installation of the plastic parts
Degradation of the plastic by exposure to aggressive chemicals, contaminants or UV radiation
Abuse by the consumer/operator

HOW TO DETERMINE CAUSE OF PLASTIC FAILURE
Determining which of the above factors caused a plastic part to fail requires a highly experienced forensic plastic failure science expert. At Plastic Expert Group, we employ world-renown plastic scientists with decades of experience in all aspects of polymer science and engineering.
In addition, we utilize state-of-the-art forensic analysis tools to determine exactly why plastic parts fail and what can be done to solve the plastic part failure problem. Our tools include:
Chemical analysis identifying incompatible chemicals like FTIR and GC-MS
ASTM tests to determine if parts were manufactured to meet specifications
Once we determine the root cause of plastic failure, we offer expert advice on how to solve the problem. If the failure was caused by poor part design, we help redesign the part. If the failure was caused by defective manufacturing, we can help improve the manufacturing operation and develop quality control tests to identify defective parts. If a part is involved in a litigation, we have extensive experience working with both Plaintiff and Defense Attorneys as expert witnesses.
