Plastic Stress Test Protocols

Polycarbonate stress crackingPolycarbonate stress cracking

High stress levels in plastic are a common cause of component field failures. Stress cracks or surface crazing near stress concentrators like threads can be a sign of future problems. Sometimes stress is not visible until the component is subject to loading or exposure to chemicals by the end user.

Connecticut Plastics has protocols for testing components for stress after machining. These range from total destructive testing to optical stress measurement. Materials most sensitive to field failures are Acrylic, Polycarbonate, Ultem, Polysulfone and Noryl.

Please consider us for your machining needs. Through special processing, Connecticut Plastics can produce a very low stress plastic component. Customers can request a lab stress test along with a production run to ensure suitablity for their application.
