How Temperature Influence Acrylic Sunglasses Display Racks

Ice will melt when environment temperature increase, and temperature affects many things in daily life. So, for acrylic sunglasses display racks, how does temperature affect it? Let's share it with you by Able Acrylic Display!

1. Affect the extension ability of acrylic display racks;

With the increase of temperature, the elongation of acrylic material increases gradually during the brittle fracture process. And the elongation at break of acrylic material reaches 5.6% at 60 centigrade. When the temperature exceeds a certain standard, the acrylic will begin to soften and the stretching process will damage the acrylic sunglasses display racks.

2. Influence the hardness of acrylic sunglasses display racks;

The hardness of acrylic material decreases as the temperature increase. In addition, the greater the load value used to measure the hardness, the lower the measured hardness value. Within a certain range, the larger the thickness of the acrylic material is, the higher the measured value will be. However, when the thickness increases to a certain extent, the measured hardness will no longer increases significantly.

3. Affect the poisson ratio of acrylic display racks;

The temperature also has a certain influence on the poisson ratio of acrylic material. The higher the temperature, the larger the poisson ratio.

4, the thickness of acrylic is different, the impact is also different;

The temperature also has influence on the impact properties of acrylic sunglasses display racks. As the temperature increases, the movement of the molecular segment of acrylic is strengthened. The macro performance is the flexibility and impact strength increase.

5. Effect on tensile strength and tensile modulus of acrylic display racks;

As the temperature increases, the tensile strength and the tensile elastic modulus of acrylic sunglasses display racks will decrease substantially linearly. The reason is that, as the temperature increases, the activity of the polymer material segment increases, and the glass state gradually becomes highly elastic and the transition of the viscous flow state. Macro performance is an increase in flexibility, and decrease in strength and modulus of elasticity.
