PI&PTFE Coating
PI/PTFE coatings are two high-performance specialty coatings, among which PI (polyimide) coatings are known for their excellent high temperature resistance, high insulation strength, and mechanical strength. They are widely used in implantable medical devices (such as insulation layers for nerve stimulation electrodes) and precision diagnostic components (such as medical sensor coatings), providing reliable protection for equipment; PTFE (polytetrafluoroethylene) coating, with its extremely low friction coefficient and excellent non stick and anti-corrosion properties as its core characteristics, is widely used on the surface of various interventional surgical instruments (such as guide wires and catheters), significantly reducing tissue insertion resistance and blood adhesion, thereby improving the smoothness and safety of surgery. Both provide key surface solutions for innovation and performance optimization of modern medical devices.

Product Details
Product Features:
Medical PI coating:
- Excellent insulation: It can effectively isolate current, ensuring the stability and safety of implantable electronic devices during operation.
- Excellent mechanical strength: The coating is sturdy and wear-resistant, providing reliable physical protection for delicate medical components.
- Outstanding biocompatibility: Mild reaction when in contact with human tissue, suitable for long-term implantation of devices.
- High chemical resistance: able to withstand the erosion of complex biochemical environments in the body and maintain stable performance.
Medical PTFE coating:
- Extremely low friction coefficient: can significantly reduce the friction between instruments and tissues, making interventional surgical operations smoother.
- Excellent non stick and anti thrombotic properties: effectively preventing blood proteins and cell adhesion, reducing the risk of thrombosis.
- Stable chemical inertness: does not react with bodily fluids and tissues, ensuring long-term safety for use.
- Smooth film-forming property: It can form a uniform and dense coating on the surface of complex shaped instruments, achieving comprehensive coverage.
Application fields:
PI (polyimide) coating is mainly used in scenarios that require precision protection and electrical stability due to its insulation, mechanical strength, and biocompatibility.
- Neural stimulation and recording equipment: used as an insulation layer for deep brain stimulation electrodes and neural signal recording arrays to ensure accurate transmission of electrical signals.
- Implantable sensor packaging: As a protective layer for implantable pressure, glucose, and other biosensors, it isolates fluid erosion and maintains signal stability.
- Fine diagnostic and treatment tools: coated on the surface of precision cables of instruments such as endoscopes, providing bending resistant insulation protection.
- Minimally invasive surgical instrument components: key components such as flexible joints used in surgical robot arms to ensure precise movements and electrical safety in small spaces.
PTFE coating mainly utilizes its extremely low friction coefficient and non adhesiveness to solve the problems of instrument passability and biocompatibility in the human body.
- Vascular intervention guide wire/catheter: coated on the surface of the intervention guide wire and peripheral nerve microcatheter, greatly reducing the resistance when it enters tortuous blood vessels.
- Tissue separation and anti adhesion: Implantable anti adhesion film is made and placed on surgical wounds to effectively prevent tissue adhesion.
- Oil free lubrication components: used for sliding parts of electric staplers, bone drills, and other instruments to achieve oil-free lubrication and avoid contaminating the surgical area.
- Drug delivery system: As an internal coating of drug elution devices or delivery lumens, it ensures smooth drug release and reduces residue.
