Urea button and resin button are the same root
Common resin button knowledge misunderstanding: Urea is also a resin?
The urea buckle and the resin buckle are the same root. Let's briefly introduce the performance of the two.
1. Generalized resin: Resin button commonly known as unsaturated polyester resin button is based on unsaturated polyester resin. Unsaturated polyester resin button can be used in 40 ° C, 50 ° C, 60 ° C or 95 ° C water. The corrosion resistance of the laundry liquid. These temperatures cover all washing methods from gentle to strong in the laundry process. The performance of the unsaturated polyester resin button mainly refers to the change of the appearance of the button in the process of making, wearing, washing, ironing, drying and storing the button, including discoloration deformation, staining of the fabric and the button after contact. Waiting for the situation. Characterization of the performance of unsaturated polyester resin buttons is washable liquid corrosion resistance, dry cleaning solvent corrosion resistance, steam ironing resistance, ironing resistance, heat head pressure pressing performance, air corrosion resistance, water resistance Performance, seawater resistance or chlorine water performance.
2. Characteristics of urea button:
1' Ordinary resin buttons can only be cooked in hot water of about 100 °C, and urine aldehyde resin buttons can reach 120 °C. As for the short-time electric ironing temperature can be higher.
2' Higher hardness and good scratch resistance.
Compared with resin buttons, urethane aldehyde resin has higher hardness, and it is also a kind of thermosetting* joint type plastic, so it has good wear resistance and is not easy to be damaged. Therefore, these buttons can be used for clothes, shirts, etc. that are often washed. On the clothes.
3' Good resistance to organic solvents
It has superior organic solution resistance than unsaturated resin buttons and, therefore, can withstand the erosion of dry cleaning agents without damage.
