Material Aging TestingEnvironmental Reliability Testing-CVC-Your Trustworthy Testing&Evaluation Expert

1.Introduction

Physical and chemical performances of non-metallic materials such as plastics, paints, rubber and textiles will deteriorate or lose because of the influence of the environmental factors like light, water and temperature in the actual use, for example, color fading of the surface, loss of gloss, cracking, embrittlement, rigidification and pulverization. This phenomena is called material aging.
The material aging test refers to the thermal-oxidative aging test performed on rubber, plastic parts, electrical insulated materials and other materials of the product, or the ventilation aging test for electronic parts and plasticized products. Aging test is divided into temperature aging, solar radiation aging and loading aging, etc.
