Industrial vacuum hoses include PU vacuum hoses and PVC vacuum hoses. So what is the difference between these two vacuum hoses?

There are two commonly used materials for industrial vacuum hoses, one is a vacuum hose made of PU material, and the other is a vacuum hose made of PVC material. Now make a comparison between the PU vacuum tube and the PVC vacuum tube.
  PU vacuum tube is made of PU plastic, and its Chinese name is abbreviated as polyurethane.
Features of   PU vacuum tube: Mainly used for abrasive solids such as dust, powder, fiber, chips and particles, gas and liquid environments, for dust removal and suction workshops, industrial vacuum cleaners, paper and textiles fiber. Antibacterial and hydrolysis, good chemical resistance; extremely resistant to abrasion and the underlying copper-plated steel wire to enhance the strength of the tube, very resistant to high pressure, vacuum and compression, high shaft strength, very smooth material, food-grade compliance: FDA 21 CFR 177.2600 and 178.2010 , EC guideline 2002/72/EC (formerly 90/128/EEC), the bending radius is approximately equal to the outer diameter, can discharge static electricity (according to BGR-132, formerly ZH 1/200) spiral wire grounding.
   structure: PU steel wire suction hose is covered with strong elastic copper-plated steel wire; wall: special top polyether-polyurethane, about 0.6mm wall thickness, spiral: elastic steel wire, stretchable.
  Temperature range: about -40℃ to +125℃, it can be about +150℃ in a short time.
The characteristics of    PVC dust suction pipe: temperature range: -20℃~70℃
   structure: elastic steel wire coated on the pipe wall: high-grade soft PVC spiral: elastic steel wire
  Characteristics: very smooth, acid and alkali resistance, chemical resistance, bending radius approximately equal to the outer diameter, discharge of static electricity (grounding screw)
   Application: Used in powdery solids (such as dust, powder, fiber), gas environments (such as steam and smoke), air conditioning and ventilation equipment
   PU vacuum hose and PVC vacuum hose are not very different on the surface, they are both built-in steel wires, but there is a huge difference between the two in terms of performance. From the material point of view, the vacuum hose made of PU material is more pure and transparent than the PVC vacuum tube. The steel wire embedded in the PU vacuum tube is copper-plated steel wire and stainless steel steel wire, which is more wear-resistant than PVC galvanized steel wire. , Resistant to stretching, and the steel wire of the PU vacuum pipe is thicker than that of the PVC vacuum pipe, which greatly extends the service life of the PU pipe. The service life of the PU vacuum pipe is 7-10 times that of the PVC pipe. . In terms of physical and chemical properties, PU dust suction tube has pressure resistance, abrasion resistance and high temperature resistance. These are far less than PVC pipes, and PU dust suction tube will not harden at minus 40 degrees. , It will not become soft or yellow under the high temperature in summer, these are also unmatched by PVC pipes.
