Most people subconsciously think that white is better than black, safer and healthier. As a manufacturer of Non-Toxic HDPE Tubes, Tengyuan will explain to you today :
First of all, the HDPE tube is non-toxic, and the black and white HDPE tubes are all made of polyethylene.
PE is a polyethylene plastic, plastic bags, plastic wrap, etc. are PE, HDPE is a high crystallinity, non-polar thermoplastic resin. The surface of the original HDPE is milky white, and is semi-transparent in a thin section.
PE has excellent days and characteristics of industrial chemicals. PE pipe for water supply is a replacement for traditional steel pipe and PVC drinking water pipe. It is necessary for the water supply pipe to withstand a certain pressure. Usually, a PE resin having a large molecular weight and good mechanical properties, such as HDPE resin, is used. Because of its high health indicators, HDPE resin has become a common source of drinking water pipes. HDPE resin has a small melt viscosity, good fluidity and easy processing, so the selection of its melt index is also wide.
The black HDPE tube is blackened at the time of production, mainly UV-resistant, and can be extended to life. This tube is mainly used outdoors. The white HDPE tube is not added with a black mother during production, and the UV resistance is greatly reduced.
Therefore, the white HDPE tube is not much better than the black HDPE tube.
As a Dredging Pipe Factory, Tengyuan produces a variety of Large Diameter HDPE Water Supply Pipe, HDPE underground drainage pipe and HDPE Underground Drainage Pipe. Welcome everyone to come to consult and order.
