[QUOTE="bergmen, post: 1154314, member: 15189"] Nylon (Polyamide) is a semi-crystalline thermoplastic in the same general category as the polyethylenes and polypropylenes. Polycarbonate is an amorphous thermoplastic in the same general category as ABS, PVC, etc. Nylon is very resistant to stress (or tension) failures, it stretches quite a bit before actual failure. Polycarbonate on the other hand is extremely strong with compressive loads and is very popular as impact resistant shields (bullet "proof" windows at banks, etc.), safety glasses, face shields and windshields. PC is very weak in tensile strength. Acrylic (Plexiglass) fractures easily with impact loads (especially with thinner cross sections) and is not a good choice for motorcycle windshields or helmet face shields as a result. Dan [/QUOTE]
