Choosing between rubber and TPE involves part performance, processing and production cost. Both categories contain different formulations, so neither has a universal performance advantage.
Consider molding methods, tooling and equipment, cycle time, finishing, tensile properties and compression set. Compare candidate grades using data obtained under equivalent conditions.
Reprocessing depends on the material system, cleanliness, formulation, intended use and performance requirements. It does not mean that all waste can be returned directly to production.
