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.
