Environmental Stress Cracking
Curbell Plastics, Inc., one of the nation’s top suppliers
of plastic sheet, rod, tube, tapes, and fabricated parts,
published a new technical paper for engineers and machinery
designers about environmental stress cracking
(ESC), the premature brittle failure of plastic materials
caused by the combination of stress and chemical contact.
The Plastic Part Failure Caused
by Environmental Stress Cracking
white paper discusses how certain
plastics are susceptible to
failure when exposed to adverse
conditions. The paper combines
knowledge from scientific literature
as well as from industry
experience to outline common
causes of ESC and how to contend
with them. The paper is
written to help with plastic material selection, part design,
and assembly in order to avoid environmental stress cracking
and costly part failures.
“Due to the nature of polymeric materials, their structural
integrity can be compromised by adverse environmental
factors such as chemicals, cyclic loading and
vibration. We are cautious when selecting and assembling
plastic parts in order to prevent premature failures,”
said Timothy Buchanan, the paper’s author and Technical
Service Engineer for Curbell Plastics.
This 17-page paper includes charts, graphs, and illustrations
explaining the most common environmental
stress cracking issues that engineers and designers encounter.
The paper concludes with techniques to reduce
environmental stress cracking, tips on proper cleaning
and how to minimize physical stress.
