Cross linked vs linear polymers
WebMar 6, 2009 · Crosslinked parts are better than linear, and linear is better than no crosslinking at all. Crosslinked parts will resist environmental stress cracking more than 15 times longer when compared with linear and with non-crosslinked parts (>1000 hours versus 72 hours versus 47 hours in ASTM D-1693). WebThe basic structure of a polymer can be used to categorize polymers into linear polymers and crosslinked polymers. The main difference between linear polymers and …
