Understanding Polymer Degradation
Polymer degradation occurs when molecular bonds are broken down, often due to a higher dose of electron beam energy than what’s used for crosslinking. This process has diverse applications across industries.
Why Polymerization Matters?
When an electron beam interacts with a molecule at a higher dose, it disrupts the molecular bonds, effectively reducing the material’s molecular weight. This ability to precisely alter materials opens up remarkable possibilities.
Practical Applications
PTFE in Lubrication
Polytetrafluoroethylene (PTFE) is known for its low friction, making it ideal as a lubricant in high-quality inks for pens and print cartridges. However, PTFE’s high molecular weight can hinder ink flow.
By applying electron beam treatment, PTFE can be broken into fine powder without fracturing, preserving its lubricating properties.
