LDPE Tubing: A Look At The Common Myths

From the bags that you carry your groceries in to the squeezable shampoo bottles in your shower, there is a pretty good possibility that these items are created from LDPE (low-density polyethylene). But not only is LDPE found in everyday items, but this highly versatile material is also heavily relied upon in the manufacturing, commercial, and industrial industries, especially in the form of LDPE tubing. While LDPE tubing is ever-valuable, the material is also one that is associated with a number of myths. To get a fair introduction to LDPE tubing, it is best to get the myths out of the way first. 

Myth: LDPE and HDPE tubing are essentially the same kind of tubes. 

LDPE and HDPE can have somewhat similar structures and appearances, and they may even show up in similar applications. However, HDPE is not the same thing as LDPE. HDPE stands for high-density polyethylene. Further, HDPE is more rigid in structure; it has better tensile strength than LDPE but is nowhere near as flexible. HDPE is a bit more resilient to temperature than LDPE, which makes it more suitable for higher-heat applications. 

Myth: You can't use LDPE in the food and beverage industry. 

LDPE tubing is heavily in use in the food and beverage industry. You can find this tubing in an array of different food-service equipment pieces, such as ice and beverage machines, and also in use to package consumer food products like squeezable condiments. LDPE does not leech chemicals or toxins into the food or fluids passing through because the material is highly chemical resilient and hard to break down. 

Myth: LDPE tubing does not stand up to heat exposure. 

LDPE tubing usually comes with a relatively high heat resistance factor in spite of the fact that the material is plastic and flexible. The LDPE material can withstand temperatures of 80°C on an ongoing basis and as high as 95°C intermittently. Therefore, LDPE tubing is suitable for a number of applications, even some that may involve a bit of heat. 

Myth: Tubing made from LDPE is only available in thin sizes because of low tensile strength. 

LDPE tubing is flexible, but it is also breakable with enough direct force. Also, the material has a lower tensile strength than HDPE as mentioned above. Just the same, however, LDPE can be formed into a number of tube sizes without making the material less durable or resilient.
