Application example: Polycarbonate (PC)

In thermoplastic applications, a significant limiting factor is the glass transition point. Through an examination of various loads applied to molded polycarbonate parts, our TMA analysis has revealed that softening takes place well before the glass transition temperature is reached. During this investigation, a pushrod with two different forces (1cN and 2cN) was used to penetrate the material, resulting in varying depths of penetration. For both evaluations, a consistent heating rate of 5K/min was maintained.
