Blow molding

Thermoplastic resin by extrusion or injection molding to get the tubular plastic billet, while hot (or heating to the softening state), placed in the fold-open mold, mold closed immediately after the billet into the compressed air, so that the plastic billet blown and close to the mold wall, after cooling off, that is, to get all kinds of hollow products.
High density polyethylene
High density polyethylene (HDPE) is a white powder or granular product.Non-toxic, tasteless, crystallinity is 80% ~ 90%, softening point is 125 ~ 135℃, using temperature up to 100℃;Hardness, tensile strength and creep property are better than low density polyethylene.Longchang petrochemical high density polyethylene has good wear resistance, electrical insulation, toughness and cold resistance.Good chemical stability, at room temperature, insoluble in any organic solvents, acid, alkali and various salts corrosion resistance;The film has low permeability to water vapor and air and low water absorption;Aging resistance, environmental stress cracking resistance is not as good as low density polyethylene, especially thermal oxidation will make its performance decline, so the resin must be added antioxidant and uv absorbent to improve the shortage of this aspect.The thermal deformation temperature of hdPE film is low under the condition of stress, so attention should be paid in application.
