During lunch hours this week I did some research on POLYMERs. The below information is from ReadingPlastic.com UHMW is a low-cost plastic that can be found in everything from hip replacements to military vehicle armor. Its properties and benefits include: • Highly resistant to abrasion and corrosive chemicals • Low friction • Extremely low moisture absorption • High impact resistance • Suitable for machining and fabrication UHMW has surface and chemical properties that are rare to find in high-performance polymers. It is very resistant to most chemicals, UV radiation, and micro-organisms.
