What are the characteristics of the production process of high-temperature quality PU steel telescopic hose?

High temperature quality PU steel wire expansion hose production process characteristics:

PU steel wire expansion hose pressure and vacuum resistance, very smooth material, good chemical resistance; Flame retardant conforms to UL-94-V2, bending radius about equal to outer diameter, can be arranged (spiral wire grounding).

Structure: coated with rigid elastic copper-plated steel wire on the pipe wall: special polyether-PUR, wall thickness, smooth inner wall, more than 10 times higher than the general PVC hose, rubber pipe wear resistance; Light weight, high flexibility, smooth inner wall, transparent, can prevent obstruction, appearance spiral Strengthening; temperature range: about-40 ℃ to 125 ℃, short time can be about 150 ℃
