Versaflex™ Thermoplastic Elastomers provided excellent sealing and overmolding for seat ventilation tube Continuous Glucose Monitors (CGM) Advanced Mobility Composite Structures

Polarity of the substrate dictates the chemical nature of the thermoplastic elastomer and hence the properties and the performance of the thermoplastic elastomer. Figure 1 shows the surface energy match of various thermoplastic elastomers with rigid thermoplastics.
