Pyramid of Plastic

The adove pyramid of plastics/polymer is a ranking of plastics according to their hazardous characteristics PVC, the least clean plastic, is at the pyramid base. Naturally biobased plastic itself has limited characteristics and can not be used in many applications without certain chemicals added. When certain chemicals are added, the biobased plastics also lose its natural cleanliness. In practice, this leaves polyethylene (PE) and polypropylene (PP) to be the cleanest plastics for general applications.

With the ISO 9002 quality system certified by FMRC, every single SYLER pipe will meet the quality of its standards.

Moreover, SYLER pipe passes all tests under standard of BS 1387/85 class M. This assures you that the thickness of the steel pipe and its thick zinc coating will result in the long product lifetime.

In connection with the cleanliness, SYLER pipe passes all the tests under standard of BS6920 Part II, one of the most stringent standards on cleanliness of water pipe, conducted by Nutek System, one of the world's leading test labs. And as from the testing report, it shows that:

:: SYLER pipe passes all the tests on water quality: taste, odor, color change.

:: The extraction of 13 different metals (after containing water for 2 months) is 20-500 times lower than the standard.

:: Growth of aquatic micro - organisms (after containing water for 2 months) is 13 times lower than the standard.
