What are catheters made of, and does catheter material make a difference? Many intermittent catheters can look similar, but the material of the tube can play a part in how firm, flexible, or easy to handle they feel.
The material of your catheter can also be important if you have a latex sensitivity or prefer products made without ingredients like DEHP or PVC.
From vinyl and red rubber to silicone and POBE, this guide explains some of the most common catheter materials and what makes each one different.
The Most Common Catheter Materials
Catheter material is only one part of choosing an intermittent catheter. Length, French size, insertion tip, coating or lubrication, and product type can affect how a catheter feels and handles.
Some people may prefer a firmer catheter for more control, while others might find a softer, more flexible material easier to use. There’s no single catheter material that works best for everyone, so it can help to understand your options.
Vinyl Catheters
Vinyl, also known as PVC or polyvinyl chloride, is commonly used to make intermittent catheters.
Depending on the product’s design and formulation, a vinyl catheter may feel relatively firm or more flexible. Some manufacturers use plasticizers to adjust the material’s flexibility.
Common Features of Vinyl Catheters
- Clear material that allows urine to remain visible during drainage
- Available in different levels of firmness and flexibility
- Depending on the product, may include a color-coded funnel end for identifying French size
- Available in uncoated, pre-lubricated, hydrophilic, pocket, and closed system catheter options
- Many options made without natural rubber latex
Here are just a few of the many high-quality vinyl catheters available at 180 Medical:
Red Rubber Catheters
Red rubber latex catheters are known for their soft, flexible feel. Because red rubber is thermosensitive, the material may become more pliable as it warms to the surrounding temperature.
Some people prefer this added flexibility, while others may find a soft catheter more difficult to control.
Common Features of Red Rubber Catheters
- Soft, flexible catheter material
- May appear red, brown, or orange, depending on the manufacturer
- Opaque rather than clear
- Not color-coded for French size identification
- Usually not suitable for those with latex allergies or sensitivities
Silicone Catheters
Some intermittent catheters are made entirely from silicone, offering an alternative to PVC- and latex-based products. Silicone catheters are generally smooth and flexible, although their firmness and handling can vary by product design.
Keep in mind that a 100% silicone catheter is different from a catheter made from another material with a silicone coating. Check the individual product information.
Common Features of Silicone Catheters
- Super smooth material
- Flexibility lies somewhere between vinyl and rubber latex
- Latex-free and often DEHP-free
- Clear for viewing urine output
- Some brands feature a color-coded funnel for easy French size identification, while others are entirely silicone
POBE Catheters
POBE, or polyolefin-based elastomer, is a flexible thermoplastic material used in LoFric® hydrophilic catheters. POBE offers a PVC-free catheter option with a hydrophilic surface coating for smooth insertion and withdrawal.
Common Features of POBE Catheters
- Flexible thermoplastic catheter
- Made without PVC, phthalates, or natural rubber latex
- Offered in different lengths, French sizes, and insertion tip styles
- Clear for viewing urine output
What Does DEHP-Free Mean?
DEHP is a plasticizer that may be used to make certain PVC products softer and more flexible. A catheter labeled DEHP-free is made without this plasticizer.
DEHP-free describes the product’s formulation rather than its base material. Check the individual product information or reach out to our catheter experts at 180 Medical if you’re looking for a catheter made without DEHP, PVC, latex, or another specific material. We’ll do our best to help!
Which Catheter Material is the Best?
No single catheter material or type is best for everyone. This is because each person’s preferences and needs are different. The firmness, flexibility, coating, size, insertion tip, and other features all play a role in what may work and feel best to you.
