The effect of heat on elongation at break
Elongation at break is a measure of a material’s ability to stretch before breaking. As temperature increases, the elongation at break of TPU filaments can decrease, leading to a reduction in their overall durability. This is because heat can cause the polymer chains in the TPU filament to relax, making them more prone to deformation and breakage.
For example, one study found that TPU filaments tested at 80°C showed a 20% decrease in elongation at break compared to those tested at room temperature.
The effect of heat on tensile strength
Tensile strength is a measure of a material’s resistance to breakage when stretched. As temperature increases, the tensile strength of TPU filaments can also decrease, leading to a reduction in their overall strength. This is because heat can cause the polymer chains in the TPU filament to break or become disordered, reducing their ability to withstand tension.
According to a study by the Society of Plastics Engineers, the tensile strength of TPU filaments decreased by 15% when tested at 100°C compared to those tested at room temperature.
Methodologies for testing TPU filaments at different temperatures
