Life prediction of polymer materials
October 16, 2020
During the use of polymer materials, due to various environmental factors, the aging phenomenon of performance degradation and even loss of use value will gradually occur, which not only causes waste of resources, but also poses safety risks. To help customers cope with aging problems, LIB combines the aging mechanism of different product materials, uses a variety of test methods to characterize and analyze the changes in the macro properties, microstructures and components of the materials during the aging process, and calculates the materials through scientific data processing methods Service life.
The purpose of life prediction test:
Calculate the service life of the material at a specific temperature and stress, predict the maximum temperature at which the material can be used for a long time, explore the service life of the material in a complex environment, and study the application performance and aging mechanism of the material.
Carry out a life cycle assessment of the materials used in advance, and the products can be regularly replaced and maintained to avoid safety accidents and property losses. This is the fundamental purpose of life estimation of polymer materials.
Application areas of polymer material life prediction:
Plastic automobile accessories, plastic pipes, plastic floors, rubber gaskets and rubber tubes, rubber tubing, wire and cable outer shells.
Method of life prediction test:
Usually use natural aging method and artificial accelerated aging method. The natural aging method is the most direct and reliable method to evaluate the life of materials, but the time is too long and the cycle of artificial accelerated aging experiments is short. It is often used to study the life of polymer materials.
Advantages: This method has a short period, good repeatability, simple theoretical derivation, and high prediction reliability.
Life characteristics index:
Apparent properties, mechanical properties, flame retardant properties, electrical properties, etc.
