How Does the DMA 303 Eplexor® Dynamic Thermomechanical Analyzer Help Achieve Product Design Goals?
Polymers – Critical Materials in Manufacturing
Polymers offer advantages of lightweight properties and ease of molding into complex shapes through diverse processes. Especially in applications where plastic components serve critical functions—such as automotive, electronics, and medical industries—their performance must strictly comply with design requirements. This demands a profound understanding of material behavior, from microscopic molecular structures to macroscopic mechanical properties.

Predicting Mechanical Behavior – Essential for New Product Design
Dynamic Mechanical Analysis (DMA) is a highly sensitive technique for evaluating material properties during design and production. It accurately determines a comprehensive range of mechanical characteristics, including stiffness, elasticity, damping, and viscoelastic behavior.
