Fiber Optic Probes for Monitoring Polymer Production Process

Polymers have excellent chemical resistance, strength, and elasticity, but such properties can hinder their chemical analysis. The quality control techniques used for measuring additive levels in polymers may vary, depending on the physical and chemical properties of them. Even slight differences in the process parameters can cause large variations in the characteristics of polymer products...
