Thermal Conductivity, Thermal Diffusivity, and Specific Heat

Introduction

At Axel Products, the basic thermal properties of thermal conductivity, thermal diffusivity and specific heat of rubber and plastic materials over temperatures ranging from -40C to 200C are measured using a transient plane source method which goes by the trade name Hot Disk(TM).

Thermal Expansion and Tg

Introduction

A PerkinElmer Diamond Thermomechanical Analyzer (TMA) is used to determine dimensional changes in materials as a function of temperature or time. It is used to measure changes in length, width, thickness and linear expansion of materials.

Accessories facilitate various measurements, including expansion coefficient, glass transition, softening, swelling, gel time, creep, stress-strain, and stress-relaxation
