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 co-efficient 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 which will alleviate supply and quality issues and allow you to focus on other things.
