How to increase the toughness of acrylic sheet?
Jul 15, 2021
Although acrylic products have the above-mentioned advantages, for most ordinary customers, if acrylic products can play an excellent product display function, it is necessary to pay attention to the toughness maintenance of acrylic materials in the production process, and for different display purposes. Adjust the toughness of acrylic products accordingly to ensure that the acrylic display stand can work with the most excellent performance.
How does acrylic increase its toughness?
1. Use rigid inorganic fillers for acrylic products to increase toughness
The addition of ultra-fine rigid inorganic fillers in the production can promote the shear yield of the material matrix during the fracture process, which can absorb a large amount of plastic deformation, which leads to the transformation of the fragile properties of the material matrix.
2. Use acrylic rigid organic filler to increase toughness
When the acrylic material is stretched, the difference between the matrix and the dispersed pellets causes the material matrix to exert a strong pressure on the rigid organic filler, thereby transforming its toughness, and the rigid organic filler particles appear "cold flow" deformation and absorption Plastic deformation can improve the toughness of the material. The amount of filler used should be determined according to the requirements of use and the specific conditions of the material.
