Polymer material performance testing
With the development of production and science and technology, people are constantly putting forward various new requirements for materials.
Materials are divided into three categories: metal materials, organic materials, and inorganic non-metallic materials. Among them, the vast majority of organic materials are polymer materials,
which are divided into plastics, rubbers, fibers, adhesives, and coatings according to their characteristics.
Due to their unique structure and easy modification and processing characteristics, polymer materials have excellent properties that are incomparable and irreplaceable to other materials,
so they are widely used in science and technology, national defense construction, and various fields of the national economy, and have become widely used materials in all aspects of food,
clothing, housing, transportation, and life in modern society.
Performance testing
Nowadays, new polymer synthesis technologies are constantly emerging, new polymer materials are emerging in an endless stream, and the performance requirements are getting higher and higher.
So what are the main performance tests for polymer materials?
Performance of polymer materials
Tests related to physical and mechanical properties: density, water absorption, viscosity (viscosity), stretching, bending, compression, tearing, shearing, impact, hardness, wear resistance, peeling, fatigue resistance, etc.
Tests related to thermal properties: melt flow rate, Vicat, thermal deformation, ash content, volatile matter, glass transition temperature, melting point, thermal weight loss, thermal expansion coefficient, brittle temperature, specific heat capacity, thermal conductivity, etc.
Tests related to electrical properties: insulation resistance, volume resistivity, surface resistivity, dielectric strength, withstand voltage, breakdown voltage, leakage tracking index, etc.
Tests related to optical properties: transmittance, haze, color, color difference, gloss, etc.
Tests related to aging properties: xenon lamp aging, ultraviolet aging, hot air aging, temperature and humidity aging, salt spray, resistance to liquid media, gas corrosion, etc.
Tests related to combustion and flame retardant properties: horizontal combustion, vertical combustion, oxygen index, smoke density, etc.
