First of all, this technology is new technology.which is different from the previous heavy lay flat hose . and indeed it will be thin from the appearance because the material and the middle weaving reinforced are different from the old technology-heavy lay flat hose
1. Because of this technology hose is high strength polyester strengthening layer in the raw material extrusion molding, very strong, and because it does not contain calcium powder to reduce the cost.
good elasticity and flexibility, good resistance to wear. The most main is to solve the problem of handling is heavy.
2. Old technology is to use cotton thread of the liner, PVC raw materials by extruder after melt infiltration to the liner layer and outer layer, so their hose if it is a back and forth on the uneven road surface friction easily grinding the outer plastic raw materials, can produce water trachoma, and add a lot of calcium powder, toughness is very poor, it is easy to break, so the plastic-coated hose just looks thick, actually on the abrasion resistance and toughness than the hose of the new technology. These two kinds of lay flat hose are like our down jackets, painted like cotton-padded jackets. The down jacket is light and light, but it has a good thermal effect, and it is made of polyester material, waterproof and fireproof, which is not easy to cut. But the cotton-padded jacket looked thick, but outside was rough, and it was flammable and broken. This is the progress of technology.
