Martindale Heat Resistance Tester

The Martens Heat Resistance Tester determines the temperature at which materials deform under heat by applying a constant bending stress and heating at a uniform rate. It is used for testing the thermal deformation properties of materials such as plastics and electrical insulating materials, verifying their heat resistance stability during quality control processes.
Selection
When selecting, pay attention to the temperature range to ensure it covers the testing standards, the fixture accommodates the sample size, and the heating rate meets the specification requirements. Consider load accuracy and displacement measurement resolution, and ensure the equipment's protection and data recording functions meet daily testing needs.

Heat Deflection Temperature Tester for Measuring the Thermal Resistance of Carbon Fiber Reinforced Plastics
This article introduces the method of testing the heat resistance of carbon fiber-reinforced plastics using a heat deflection temperature tester. The instrument applies a fixed load to the material while increasing the temperature, measuring the temperature at which the material reaches a specified deformation, thereby evaluating its short-term resistance to thermal deformation.
Vicat Softening Point Tester measures the heat resistance of plastics.
This article introduces how a Vicat softening point tester measures the heat resistance of plastics. During the test, the instrument applies a fixed load to the plastic sample and heats it at a constant rate. When the flat-ended needle penetrates the sample to a depth of 1 millimeter, the temperature at that moment is recorded, which is known as the Vicat softening point.
Comparison of Vicat Softening Point Tester and Heat Deflection Temperature Tester in Assessing the Heat Resistance of Resins
This article compares the differences between the Vicat softening point tester and the heat deflection temperature tester in evaluating the heat resistance of resins.
Vicat Softening Point Tester evaluates the heat deformation resistance of resins.
The Vicat softening point tester is used to measure the thermal deformation resistance of resins. It heats and applies pressure to the specimen until it deforms by 1 millimeter, recording the temperature at that point as the softening point.
Temperature gradient control in high-temperature ovens during thermal resistance testing.
The heat resistance test simulates the performance of materials under high temperatures using a high-temperature oven, and the accuracy of its results is highly dependent on the uniformity of temperature inside the oven. If the temperature gradient is poorly controlled, it can lead to uneven heating of samples from the same batch, compromising the validity of the test.
