What is the difference between PU steel wire vacuum hose and rubber vacuum hose

There are many types of vacuum hoses. The rubber vacuum hoses and PU vacuum hoses we are talking about today have many similarities. Below we will give a brief introduction to the industrial vacuum hoses of the two materials. Have a deeper understanding so that you can make a more correct choice when you buy in the future.
  The application history of    rubber vacuum cleaners is very long, but as a rising star, PU vacuum cleaners are encroaching on the territory originally belonged to rubber vacuum cleaners, but each product has its own advantages, especially in some special occasions. The rubber vacuum tube still plays an important role.
  Rubber vacuum tube is non-toxic, odorless, environmentally friendly, UV resistant, high and low temperature resistance (-80 to 300 degrees), strong resilience, compression and deformation resistance, oil resistance, stamping resistance, acid and alkali resistance, abrasion resistance, and difficult The properties of combustion, withstand voltage, electrical conductivity, etc., have many similarities with PU vacuum pipes, but in terms of use, rubber vacuum pipes have a larger application range, mainly in terms of temperature, and can be made super strong. Products resistant to high and low temperatures, but relatively speaking, the tear resistance and abrasion resistance are much different than those of PU vacuum hoses. Generally speaking, the abrasion resistance of PU vacuum hoses is 5-8 times that of rubber hoses, and the tear resistance is about In 3-5 times, and the temperature range of its use also meets the needs of the conventional environment, except in some special occasions, you can choose to use the PU dust suction tube, because it is more portable, flexible, and durable.
  PU steel wire dust suction hose is generally used in suction occasions, there are abrasion solids, such as dust, powder, fiber and debris, active media such as oil vapor and welding fumes, and industrial dust removal and suction hoses. PU dust suction hose has very smooth characteristics, anti-microbial and hydrolysis, good chemical resistance and mineral oil resistance; good UV and ozone resistance; high tensile strength and tear strength, high stretch and compression ratio 4:1, small bending radius, not easy to kink; food grade conforms to: FDA 21 CFR 177.2600 and 178.2010, EC regulation 2002/72/EC, RoHS regulation; can discharge static electricity, ground through spiral wire.
  Structure: The tube wall is covered with elastic steel wire, extruded in a strip shape, and the wall thickness is about 0.4 mm;
   Material: pipe wall: special polyether-polyurethane, spiral wire: elastic steel wire;
  Temperature range: about -40°C to +125°C, up to +150°C in a short time
