PVC pipe grade: white and gray PVC pipe, which one better?

If you think gray is better, then you are wrong. But if you think white is better, you are not right either. Then which one? The answer is dependent on the manufacturer and the commitment of the pipe manufacturer itself. PVC pipe grade is not depends on its color.

In detail I will explain the meaning of my statement above. As a businessman and Managing Director of one of the leading PVC pipe manufacture in Indonesia I just want to share one of the myths about PVC pipe grade comparison between white and gray PVC pipe.

in general, a quality PVC pipe is PVC pipe with ideal composition. Ideal in the sense of the word contains PVC (poly vinyl chloride) in large quantities, about 80% -95% of the total mixture of the material and the rest is filler and addictive. I will explain about the addictive for PVC in other posts. The more filler the pipe, the lower the quality results.

To determine the color of the pipe, we simply use the color pigment. The color pigment itself is included in one component of what we call addictive. Color pigment has only a very small effect under 5% of the total composition of materials used in processing PVC pipe products. It did not affect the PVC pipe grade.

PVC gray pipe commonly in the processes is mixed with recycled PVC materials because the material will not be visible in gray. In this case, recycled materials can not be mixed on white PVC pipe cause it will damage the whiteness of the pipe. The percentage is depend on the company itself.

The more the recycle material used, the more it decreases the quality of the pipe. This is one reason people think that PVC gray pipe quality is worse than white PVC pipe.

However, that opinion is not always true because in white PVC pipe we can easily add white filler into the material of  PVC white pipe product. You will never find out the difference visually.

We can concluded that the actual PVC pipe grade does not depend on the color, but it depend on the composition of the PVC pipe product examine by the manufacturer of the PVC pipe. They are the one who decide the PVC pipe grade.

For example:
PVC pipe factory Denya produces PVC pipe with two common colors i.e gray and white, with each color having two different product categories.
You can choose between:
– a super-quality white PVC pipe, or a white color with a normal quality on good price and a super-quality gray PVC pipe
– or a gray color with a normal quality on a good price as well.

In the conclusion, we cannot simply judge PVC pipe grade by the color.
