We know that the acrylic display frame is very sensitive to temperature. In case of high temperature, the acrylic display frame may deform, and some acrylic display frames may be placed outdoors or released to high temperature. How to improve the heat resistance of the acrylic display frame?
In fact, there are many methods to improve the heat resistance of acrylic, and each method has its own advantages and disadvantages. Some methods can improve the heat resistance of acrylic, maintain transparency, and reduce other properties. In order to improve the heat resistance and other properties of acrylic display frame at the same time, it is sometimes necessary to use a variety of improvement methods at the same time.
For example, the main function of PHMI is to improve the heat resistance, and the main function of MAA is to improve the refractive index. In this way, PHMI is the main monomer, and MAA is the side monomer. The resulting copolymer not only improves the heat resistance, but also the refractive index, so the terpolymer has both high heat resistance and low moisture absorption. The Vicat softening point temperature of mma-phmi-nma copolymer reaches 137 ℃, and the water absorption rate is increased It is about 25% lower than PMMA, and other properties are similar to PMMA.
Now there are many materials scholars who are constantly striving to develop a high-performance acrylic display frame, so as to expand its application and improve the economic benefits of acrylic display frame. We are also very looking forward to contact us if you need acrylic display frame.
