Urea-formaldehyde cover is the most commonly used toilet cover. Urea-formaldehyde is also urea-formaldehyde resin. Of course, there are many other aliases, such as urea-formaldehyde resin, cement asbestos board and fiber amphibole, etc.
For urea-formaldehyde material, it is generally soluble in water, and it is relatively easy to cure. The cured urea-formaldehyde is non-toxic, Colorless and good light resistance, it is one of the very good environmentally friendly building materials. The color is firm and the color will not change whether it is used for a long time or thermoforming. If you want to make brightly colored products, you can add various colorants for dyeing. Treatment, urea-formaldehyde is hard and scratch-resistant, and is also corrosion-resistant and oil-resistant. The price is cheap, but it is easy to absorb water, and the heat resistance is not high, but it does not affect the performance of the toilet lid. The toilet lid made of urea-formaldehyde is very durable. So use more.
PP material is the first to appear, also known as polypropylene. Similar to PVC material, PP material is also cheap and easy to process, but its strength, hardness and heat resistance are better than PVC material, and it can be used at about 100 degrees Celsius.
It has good acid and alkali resistance, and can resist a variety of organic solvents and acid and alkali corrosion. Common acid and alkali organic solvents have little effect on it. And it is non-toxic, tasteless, low density, has good anti-electric performance and high frequency insulation, and is not easily affected by humidity.
