It increases tensile strength, abrasion resistance, and toughness.

Crosslinked materials can be stretched while hot and "frozen" in place; when reheated, the crosslinks pull the material back to its original shape (the principle behind heat-shrink tubing). 5. Why E-Beam Over Chemical Methods?

When two radicals on neighboring chains meet, they form a permanent covalent bond. This "bridge" is the crosslink. 3. Structural Transformation
