What is HDPE plastic?
HDPE means High density Polyethylene. What is HDPE plastic? High density polyethylene is a thermoplastic made from petroleum. Its high density allows it to withstand greater stress. HDPE does not contain BPA, phthalates, heavy metals or allergens. It is the most environmentally stable of all plastics and does not emit harmful gases into the environment. As one of the most widely used plastics, it is used in a variety of packaging and commercial applications.
Compared with ordinary polyethylene, the advantages of high density polyethylene HDPE
-
Higher density and more molecular content
The molecular content of ordinary Polyethylene is between 1000 and 15000, and the molecular content of high density Polyethylene is between 20000 and 30000. The density of ordinary Polyethylene is between 0.91~0.92/cm^3, and the density of high-density Polyethylene is between 0.94~0.96, which means that the optical cable sheath products made of HDPE can withstand greater external forces.
-
Greater strength and better wear resistance
HDPE’s strength and wear resistance are significantly better than PE. And it can withstand more wear and tear. It is more suitable for outdoor optical fiber cable sheath applications. Such as pipelines and direct burials.
-
Better heat resistance and cold resistance
HDPE has good heat resistance and high softening. The unpredictable weather and environment outdoors have high weather resistance requirements for optical cable sheaths, and HDPE’s excellent heat and cold resistance just meet them.
-
Better chemical stability
At room temperature, high-density polyethylene is insoluble in any organic solvent. It has good resistance to acids, alkalis and common salt compounds. Therefore, for indoor bare optical cables wired on the ground, the optical cable sheath made of HDPE can well ensure its corrosion resistance to substances such as acid rain and stagnant water.
-
Better processing performance
In addition to being used to make sheaths in the field of optical cables, high-density polyethylene is also used to manufacture containers and other product. For example, distribution bottles, washing bottles, pipes, computer component plastic bags and other molding laboratory equipment due to its good processing performance.
Environmental friendliness of high-density polyethylene
The environmental friendliness of high density polyethylene is reflected in many aspects. First, the energy consumption required to produce HDPE is only a small fraction of the energy consumption required to produce iron from iron ore. Secondly, HDPE can be recycled and reused. Such as optical cable sheaths made of recycled materials, waste and recycling containers, fences and furniture, etc. And HDPE recycled plastic has excellent resistance to salt spray, oil, moisture and other properties, and is relatively stable to the environment. No harmful gases are produced when burned. HDPE itself does not contain substances such as BPA, heavy metals or human allergens. Which makes it the preferred environmentally friendly material for making products in various industries.
Common uses of high-density polyethylene
In construction, it can be used to make environmentally friendly resin bases, fences and furniture, etc.
In catering, it is used to make food storage containers, food preparation products, etc.
It can also be used to make outdoor signs, drains and toys, etc.
Summary
High density polyethylene is in line with the concept of sustainable development, is environmentally friendly, and will be used in more fields in the future.
