What is HDPE?

High density polyethylene (HDPE) is a white powder or granular product. Non-toxic, tasteless, crystallinity is 80% ~ 90%, softening point is 125 ~ 135℃, the use of temperature can reach 100℃; The hardness, tensile strength and creep property are better than low density polyethylene. Good wear resistance, electrical insulation, toughness and cold resistance; Good chemical stability, at room temperature, insoluble in any organic solvent, acid, alkali and all kinds of salt corrosion resistance; Thin film to water vapor and air permeability is small, low water absorption; Poor aging resistance, environmental stress cracking resistance is not as good as low density polyethylene, especially thermal oxidation will reduce its performance, so the resin must be added in antioxidants and ultraviolet absorbent to improve this deficiency.

Filling Long glass fiber

The tensile strength of polyethylene can be improved obviously when the amount of glass fiber is 30% ~ 40%. With the continuous increase of the addition amount, the increase of tensile strength did not change significantly, but tended to be stable.

The addition amount of glass fiber has a great influence on the elastic modulus of polyethylene plastic materials. With the increase of glass fiber addition amount, the elastic modulus of polyethylene plastic materials will continue to increase and reach a certain value.

A adição de fibra de vidro tem um grande efeito no alongamento à ruptura de materiais plásticos de polietileno. Com o aumento da adição de fibra de vidro, o alongamento na ruptura dos materiais plásticos de polietileno continuará a diminuir. Até um certo valor, a fragilidade do polietileno modificado com fibra de vidro será mais óbvia, quase igual à fragilidade da fibra de vidro.
