High-density polyethylene [HDPE] and low-density polyethylene [LDPE] derive from the polymerization of ethylene. Polyethylene is the world’s most utilized plastic. Manufacturers of HDPE and LDPE polymers generally take polyethylene pellets and, using heat and pressure, extrude a resin into the shape of tubing or various custom profiles, depending on usage.
The different chemical composition between HDPE and LDPE is determined through the polymerization method. The main difference between the two – dense and rigid versus flexible – determines the uses for each. The demand for both HDPE and LDPE tubing and custom shapes is enormous and covers a vast array of products that impact every aspect of our lives.
Let’s look at applications for both products:
HDPE Tubing and Custom Shapes Applications
Aside from being rigid, HDPE has high impact, chemical, and abrasion resistance; has a low coefficient of friction, and excellent wear properties.
Among the applications for HDPE tubing and custom shapes are:
Automotive
Conveyor
Geophysical
Industrial
Material Handling
Military and defense
Wire and cable
LDPE Tubing and Custom Shapes Applications
The beauty of LDPE is it has most of the benefits of HDPE but is flexible.
Among the applications for LDPE tubing and custom shapes are:
Automotive
Conveyor
Geophysical
Industrial
Material Handling
Military and defense
Wire and cable
What to Look for When Buying HDPE and LDPE Tubing and Custom Shapes
There are numerous manufacturers of HDPE and LDPE tubing and custom shapes. If you are looking for a company to partner with you should consider the following:
Years of experience
The sophistication of their extrusion process
Their ability to meet your specs in terms of size, etc.
Their track record on completing projects on time
Cost
Who their customers are
Ideally, if you choose the right company you will build a long-term relationship that will alleviate supply and quality issues and allow you to focus on other things.
