The picture above lists the main materials and auxiliary materials most commonly used in die-cutting factories. Let's talk about the foam in the main materials:Polyurethane foam is also called polyurethane elastomer.Polyurethane is an emerging organic polymer material and is known as the "fifth largest plastic". Because of its outstanding performance, it is widely used in many fields of the national economy

Foam is a high molecular polymer with many small cells, the solid phase is a polymer matrix, and the small cells are filled with gas.The foam is divided into open and closed cells according to the structure of the cell. The cell connected with the cell is called the open cell structure, and the cell that is not connected with the cell is called the closed cell structure

"Thermal conductive silicon film" is a kind of thermally conductive material synthesized by a special process with silica gel as the base material, adding various auxiliary materials such as metal oxides. In the industry, it is also called thermally conductive silicone pad, thermally conductive silicon film, soft Thermally conductive pads

Thermosetting polyimide film has excellent thermal stability, chemical resistance and mechanical properties, high tensile strength and stable chemical properties. The application is also very wide,Application in winding electromagnetic wire.The film is used as the substrate, and the perfluoroethylene propylene emulsion is coated on one or both sides to form an adhesive tape, which can be wrapped around the bare copper wire and then enter the high-temperature furnace. The film shrinks and the wire is tight, so that the wrapped The adhesive tape layers are melted into a whole, and when the wire is cooled out of the high-temperature furnace, add a pair of pressure rollers on both sides of the wire to improve the bonding strength between the adhesive tape layers

3M double-sided tape is very heat and corrosion resistant, and can maintain stable adhesion under temperature changes; and it is not easy to stick to surfaces such as metals, gold-plated surfaces, plastics, wood, paper, silicone, plastics, etc. They all have good adhesion to absorb external impact, vibration and noise. They can prevent corrosion between different metals, have super high adhesion, and have good adhesion durability in high and low temperature environments.

PC performance advantages: high transparency, scratch resistance, high temperature resistance, environmentally friendly flame retardant, good insulation, etc...PC is used in the field of flat panel LCDs:PC is used in the medical field: With the improvement of people's living standards, the number of diabetic patients is increasing day by day, and the demand for blood glucose test strips is greatly increased. Because polycarbonate has good electrical insulation, polycarbonate (PC) film can be used for blood glucose meter test paper after special treatment
