HDPE introduce

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. High density polyethylene film under the condition of stress thermal deformation temperature is low, should pay attention to the application.

Long Glass Fiber filling

High density polyethylene (HDPE)/ glass fiber (LGF) composites were prepared by twin-screw extrusion mechanism, and the mechanical properties and non-isothermal crystallization behavior of HDPE/LGF composites were studied. The results show that the impact strength of the composite can be improved by MAH-g-POE, and the interface bond between the glass fiber and HDPE is good. The Avrami index (n) of the composite does not change with the cooling rate.

The effects of HDPE on the flow properties of PP and its mechanical properties, and the effects of the flow properties of PP/HDPE blends on the mechanical properties of LGF/PP/HDPE composites were studied. The results show that HDPE can not only improve the impact performance of PP, but also improve the liquidity of PP. The mechanical properties of LGF/PP/HDPE composites, such as tensile strength and bending strength, are mainly affected by the flow properties of the matrix, but have little effect on the mechanical properties of the matrix itself.

Frequently asked questions

1. Under what circumstances can long fiber replace short fiber? What are the common alternative materials?

A: Traditional staple fiber materials can be replaced with long glass fiber and long carbon fiber LFT materials in the case of customers whose mechanical properties cannot be met or where higher metal substitutes are desired. For example, PP long glass fiber is often replacing nylon reinforced glass fiber, and nylon long glass fiber is replacing PPS series.

2.  How to choose the fiber content of the product? Is the larger product suitable for higher content material?

A: This is not absolute. The content of glass fiber is not more is better. The suitable content is just to meet the requirements of each products.

3. If want to increase the anti-aging properties of the product, is it possible to add anti-UV agent to the material?

A: You can choose some materials which are better resistant to aging, and then add some antioxidants and UV absorbers to the materials, to improve the aging resistance of the products.
