Generally cheap PVC garden hose is made of PVC material processing, also known as PVC hose, inside also has the braid, but service life, appearance, odor, compressive degree, the tensile strength and work stress are obviously different.
First is PVC garden tubing smell, did not see its content, first to smell the smell, the smell, the inferior polyvinyl chloride (PVC) is made by PVC material containing pbdes in the release, pbdes serious harm to human and the natural environment, the smell of it has a strong persistence, and strong fat-soluble, cause a harm to human liver and nervous system, thyroid endocrine interference at the same time, easy to cause cancer.Now many countries such as the United States and Europe has successively introduced in 2003 and 2003 files, prohibit this kind of PVC garden tube manufacture, PVC garden tube manufacturing must comply with ROHS and REACH standard, can use.
Second, the pressure effect is poor, the adhesion strength is poor, the cold is easy to be hard, the hand is like a stick, easy to fold;Some PVC garden hose although winter feels quite soft, is hoses production with hardy plasticizer, plasticizer is phthalic acid ester, is chronic poison to human body, easy to cause liver and kidney function decline, the red blood cells in the blood of the, respectively and carcinogenicity.
The third braiding layer is made of inferior polyester material. The inner layer, outer layer and interwoven layer are not bonded easily, which is easy to peel off, thus affecting the working pressure and service life of PVC garden hoses.
