HDPE plastic hose main HDPE high density polyethylene as the main raw material, according to the material quality standard requires smaller dose, the injection process, medicinal high-density polyethylene tube can be divided into oral liquid and medicinal high-density polyethylene YBB oral solid hose.

HDPE English full name High DensityPolyethylene, High density polyethylene, can also be referred to as the low pressure polyethylene. An opaque white wax material, weight is lighter than water, the proportion of 0. 941-0. 960, softness and toughness, high crystallinity and nonpolar thermoplastic resin. High density polyethylene is a kind of white powder granular products, non-toxic, tasteless, density at zero. 940-0. 976 g/cm3 range; Crystallinity is 80% ~ 90%, softening point is 125 ~ 135 ℃, using temperature is 100 ℃; Melting temperature of 120 ~ 160 ℃, for larger molecular materials, the chemical stability is good, at room temperature, does not dissolve in any organic solvent, acid, alkali and corrosion of various salts; Thin film of water vapour and air permeability of small, low water imbibition.

HDPE plastic hose main characteristic resistance to acid and alkali, solvent resistance, good electrical insulation, low temperature, can still maintain a certain toughness. Surface hardness, tensile strength, stiffness and mechanical strength higher than that of LDPE ( Low density polyethylene) , close to PP ( Polypropylene) , is better than PP toughness, but the surface finish is better than PP.
