HDPE High Density Polyethylene
1.Introduction
HDPE has several properties that make it ideal as a packaging and manufacturing product. It's stronger than standard polyethylene, acts as an effective barrier against moisture and remains solid at room temperature. It resists insects, rot and other chemicals. It is easily recyclable and can be used again and again. Recycled HDPE creates no harmful emissions during its production or during its use by the consumer. Also, HDPE leaks no toxic chemicals into the soil or water.
HDPE is one of the most commonly used plastics in the world. It is typically found in milk jugs, plastic bags and refillable plastic bottles. In addition to plastic lumber and recycled plastic furniture, recycled HDPE is used to manufacture lawn and garden products, buckets, crates, office products and automobile parts.
2.Grade
HDPE pipe grade can be used in the production of pressure pipes, such as pressurized water pipes, fuel gas pipelines and other industrial pipes.
HDPE Injection grade, red, blue, green,
HDPE Blow grade, white, grey, black
HDPE Pipe Grade black pellet
HDPE coating grade
And So On

4.Products Properties
High density polyethylene for non-toxic, tasteless, no smelly white particles, melting point is about 130 °C, relative density of 0.941 ~ 0.960. It has good heat resistance and cold resistance, chemical stability, but also has high rigidity and toughness, good mechanical strength. Dielectric properties, environmental stress cracking resistance sex also is good.
5.Storage:
Shelf life: It should avoid damp, contaminated and direct sun light during transport.And should be stored in ventilated and dry place. Do not put it with flammable and corrosive substances together,and away from the fire.
