We give a short answer on the FAQ page but it is accurate. It is totally dependent on your specific product’s application.
Hopefully, you have created a Product Design Requirements Specification for your product or something like that type of a document. Within it, you have documented what types of stresses your product (and its associated plastic) needs to stand up to. Some of those are in no particular order:
Environmental – temperature range in use, temperature range in storage/shipment, temperature transition profile, dust/dirt exposure, humidity, atmospheric pressure
Physical – handheld, tabletop, drop resistance, shock & vibration exposure, fluids exposure i.e. water submersion, water splashing, cleaning agent exposure.
The list can go on for some time.
For each of these scenarios there is a resin or composite that will meet the requirements specified. In some cases more than one. Just like electronics, resins & composites can and do go obsolete. Selecting primary and alternate materials can help reduce life cycle exposure.
