Radiation Crosslinking Boosts Nylon Properties
Demand for more robust plastics is creating new opportunities for radiation-crosslinked nylons, including nylon 6 and 66, which can serve as cost-effective alternatives to higher-cost, high-heat thermoplastics. Crosslinked nylons have higher heat resistance than their standard counterparts, along with better physical properties and abrasion resistance. Adapted from a paper presented at SPE ANTEC 2012.
