Top-Tier Materials
for Advancing
Enteral Devices
In the realm of medical device manufacturing, the pursuit of excellence and innovation is paramount. This is why we use only high-quality materials for the manufacture of our products to ensure long product life and safe application.
- High-grade medical Silicone for our gastrostomy tubes
- Soft, flexible Polyurethane for our Extension Set tubings
- Break-resistant TRITAN™ for our enteral connectors
Polyurethane
We prefer Polyurethane (PU) over PVC for the tubing of our danumed® Extension Sets due to its exceptional qualities:
- High Biocompatibility
Polyurethane is a biocompatible material, reducing the risk of adverse reactions and irritation, making it suitable for long-term use. - No Need For Plasticizers
Unlike PVC, polyurethane does not require plasticizers to remain flexible and soft. Plasticizers like phthalates can leach harmful substances with potential health risks for patients. - Resistance To Kinking
Polyurethane tubes are less prone to kinking, which is crucial for maintaining a consistent flow in enteral feeding. - Durability And Flexibility
PU remains its flexibility and elasticity over time and also has excellent tensile strength and elongation properties. - Enhanced Flow Range
PU tubes typically have thinner walls than PVC tubes, providing a larger inner diameter while maintaining the same outer diameter, thus enhancing the flow area for enteral feeds. - Patient Comfort
Polyurethane is softer, more flexible and more comfortable for patients, especially for long-term or sensitive applications.
TRITAN™
TRITAN™ is our material of choice for our button connectors and for the core pieces of our ENFit® connectors for the following reasons:
- Durability: It is a lightweight, robust plastic material known for its resistance to aggressive solutions and medicines.
- Stress crack resistance: TRITAN™ reduces the risk of stress cracks and supports the break-resistant application of enteral devices.
- Structural integrity: It can withstand the rigors of everyday use without compromising the device’s structural integrity.
Considering these factors, we are confident that TRITAN™ can greatly enhance the reliability, safety and longevity of our danumed® products.
Latex-free / DEHP-free / BPA-free
For the manufacture of all our enteral feeding products, we uncompromisingly use high-quality materials, all of them are latex-free, DEHP-free and BPA-free. Using materials that are biocompatible and non-toxic is essential to safeguarding the health of vulnerable patients who rely on safe enteral applications for their nutritional and medical needs.
