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