Plastic pipe cap

The products of plastic pipe caps can be divided into three categories: general plastics, general engineering plastics, and special engineering plastics, in order of increasing performance and price, and present a stepped distribution. The universal plastic located at the bottom of the staircase has a single performance, low price, and is also common in daily life. Plastic products include five major varieties, namely polyethylene (PE) and polypropylene (PP)

1. The additive mixing of color and light for plastic flange covers

2. Plastic pipe cap color pigment mixture

3. Subtraction and mixing of color pigments inside the pipe mouth, color and light mixing

4. Mixing of color pigments for plastic pipe caps (subtractive mixing)

The color scheme for plastic pipe caps and plastic flange covers usually uses a mixture of red, yellow, and blue pigments. Red refers to the plastic valve cover that allows red wavelengths to pass through and absorb green and other adjacent color wavelengths, giving the impression of red. Yellow and blue follow the same principle.
