J.K thermoforming acrylic sheet

J.K thermoforming acrylic sheet PMMA Diffuser for Thermoforming  is kind of extruded product, which combine PMMA resign and different scale of diffusion agent, features distinct high light diffusion and high light transmission. It’s kind of translucent milk white material, which one side is matte, another side looks like orange peel texture. It’s an idea lampshade material for LED ceiling light. Thermoforming  is a manufacturing process where a plastic sheet is heated to a pliable forming temperature, formed to a specific shape in a mold, and trimmed to create a usable product.

The temperature acrylic products

The use of a wide range of  acrylic sheet  products, we can say in our daily lives  can often be seen. But we should pay attention to the temperature of acrylic  products can withstand what is, to answer them below: 1, acrylic article is made from polymethyl methacrylate-cresol,  p-cresol-containing polymethacrylate polar side group, with a strong hygroscopic  property and water absorption in the acrylic sheet generally must be kept dry,  78 need dried 5-6h dried under ℃ -80 ℃. 2, acrylic polymer is an invisible, its scope are reduced shrinkage, are  generally in the 0.45% -0.9, so the time for the production of acrylic products  provide good precision molding conditions are generally formed is very  accurate. 3, the polymethyl methacrylate-cresol adaptation range of the ambient  temperature of the fluid does not have a general, but has a non-Newtonian fluid,  and therefore at high temperature, the melting viscosity of t...
