Overview

This article will take a deep look at the test methods and relevant standards for high temperature wear-resistant plastics. Through a thorough evaluation, companies can choose the material that best suits their needs and promote the advancement of industrial applications.

Test Method

Thermal stability test

Thermal stability is an important performance indicator of high-temperature wear-resistant plastics, and its testing methods mainly include thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). TGA evaluates the thermal stability of materials by measuring the curve of material mass change with temperature; DSC determines the thermal performance characteristics of materials by measuring the heat absorbed or released by the material.

Wear resistance test

Wear resistance is an important indicator to measure the long-term performance of high-temperature wear-resistant plastics in a friction environment. Taber abrasion tester and rubber wheel abrasion tester are common testing equipment. Taber abrasion tester produces wear on the material surface by rotating the wear disk to evaluate the wear resistance of the material; rubber wheel abrasion tester applies load through the pressure wheel to test the wear depth of the material surface.

Deformation and strength testing

The deformation and strength of high temperature wear-resistant plastics can be evaluated through tensile strength test, bending strength test and compression strength test. The tensile strength test measures the stress when the material breaks through the tensile device; the bending strength test measures the maximum stress before the material fails through the three-point bending method; the compression strength test measures the deformation and failure of the material when it is under pressure.

Related standards

When testing high temperature wear-resistant plastics, it is necessary not only to follow scientific methods, but also to refer to international and domestic testing standards. The main standards include:

ASTM Standards

ASTM D4060: used to evaluate the abrasion resistance of materials; ASTM E1131: For thermogravimetric analysis of materials.

ISO Standards

ISO 11357: for differential scanning calorimetry; ISO 9227: Corrosion tests are used to evaluate the environmental resistance of materials.

in conclusion

By conducting systematic thermal stability, wear resistance and strength tests on high-temperature wear-resistant plastics and referring to relevant international and domestic standards, companies can more scientifically select high-performance materials to meet specific application requirements.
