FEP Heat Shrink Tube
The FEP Heat Shrink Tube boasts a composition rooted in fluorinated ethylene propylene (FEP), a thermoplastic polymer renowned for its exceptional properties in medical applications.
FEP exhibits a unique combination of characteristics that make it ideally suited for medical tubing. Its molecular structure imparts remarkable clarity to the tubing, allowing for optimal visualization of fluids and instruments during medical procedures, essential for accurate monitoring and precise manipulation.
Features
- Lower heat shrink temperature:FEP heat shrink tubing has a lower heat shrink temperature than other fluorinated heat shrink tubing, such as PTFE, PFA
- It has better flexibility, light transmittance and high lubricity than PFA.
- The recommended shrinking temperature is 80℃-240℃. The shrinking temperature and shrinking time vary depending on the design.
- Demaxcan provide FEP heat shrink tubing with shrinkage ratios of 1.3:1, 1.6:1 and 1.8:1.

PU Braided Tube
The Demax PU Braided Tube is constructed using polyurethane (PU), a high-performance polymer known for its excellent mechanical properties and chemical resistance. This tubing is reinforced with a braided layer, providing enhanced strength and resistance to kinking and collapse. It is manufactured to meet the stringent standards of the medical industry, ensuring biocompatibility and safety for patient use. The tubing is free from latex, phthalates, and other harmful substances, minimizing the risk of adverse reactions or complications.
PTFE Liner
PTFE (polytetrafluoroethylene) is a synthetic fluoropolymer that is used as a liner in catheters due to its unique properties. PTFE has a very low coefficient of friction and is a highly durable material with excellent tensile strength. Catheter liners made of PTFE can withstand the stresses of use in medical devices and resist breaking or tearing.
PTFE is used as a liner in catheters because it provides a smooth, low-friction surface that helps reduce the risk of infection and tissue damage. They are also biocompatible so that most people won’t experience an allergic reaction or any negative response.
Punching
Precision Medical Tubing Services Punching from Demax involves the precise creation of perforations, holes, or patterns in medical-grade tubing using advanced punching methods and equipment. The tubing material, typically made from medical-grade polymers such as polyethylene (PE), polyurethane (PU), or silicone, is carefully selected for its biocompatibility, flexibility, and durability. During the punching process, specialized punches and dies are used to create holes of specific sizes, shapes, and configurations in the tubing, allowing for precise control over the perforation characteristics. Each punched hole is inspected and verified to ensure that it meets the required tolerances and quality standards. Demax’s expertise in precision punching ensures that punched medical tubing maintains its structural integrity, biocompatibility, and performance, meeting the demanding requirements of medical device manufacturers and healthcare professionals.
