Key Specifications for Polyimide Tubing

Dimensions and tolerances

Choosing polyimide tubing with exact sizes is very important. Small size mistakes can hurt how well it works. For example, wrong thickness can cause big stress errors in tests. To prevent this, use tools like micrometers or automated devices. Standards like ISO 527-1 and ISO 527-2 stress the need for accurate measurements for good results.

Polyimide tubing comes in many types and sizes to fit designs. Manufacturers make tubing with smooth surfaces and strong columns for steady performance. Always check the supplier's tolerances to match your needs.

Thermal resistance and electrical insulation

Polyimide tubing is great at handling heat and chemicals. It can survive very high temperatures, making it perfect for tough jobs. For example, it works at 240°C for 20,000 hours and up to 400°C. This heat resistance makes it last longer in hot conditions.

It also provides excellent electrical insulation. Its strong dielectric strength stops electrical failures, keeping devices safe. Compared to PET or PTFE, polyimide tubing insulates better, making it a top choice for industries needing high electrical safety.

Flexibility and mechanical strength

Polyimide tubing is both strong and flexible, fitting many uses. Its tensile strength of 172 N/mm² and hoop stress of 76 N/mm² make it tough under pressure. It also resists kinking, which helps in tight or moving spaces.

The tubing bends easily without losing its shape. This flexibility and strength make it great for precise and adaptable designs. Whether for medical tools or aerospace parts, it performs reliably.

Tip: Think about how much strength and flexibility your project needs. Picking tubing that matches these needs will make it work better and last longer.

Coating compatibility and options

When picking polyimide tubing, think about its coating compatibility. Coatings improve tubing by adding features like low friction or safety. But not all coatings work well with polyimide tubing. Knowing how coatings and tubing work together gives better results.

The base material, polyimide film, works with many coatings. For example, silicone coatings stick well and stay flexible. Fluoropolymer coatings, like PTFE, are also common. These coatings lower friction and help in tools needing smooth surfaces, like medical devices.

Think about where the tubing will be used when choosing a coating. If it faces heat, pick a heat-resistant coating. For example, heat-safe coatings work well in cars or planes. For medical tools, biocompatible coatings like Parylene are safer and more reliable.

Tip: Ask your supplier if the coating fits polyimide film. Testing coated tubing in real use can prevent problems.

Choosing the right coating makes polyimide tubing last longer and work better. This ensures it meets your project’s needs.

Matching Polyimide Tubing to Your Application

Environmental factors (temperature, pressure, and chemical exposure)

Choosing the right polyimide tubing depends on its environment. Things like heat, pressure, and chemicals affect how it works. When temperatures rise, the material's polymer chains move more. This movement creates tiny spaces, letting chemicals seep in. Over time, this can cause small holes on the tubing's surface. High heat and chemicals make this worse.

Tests prove these effects. In one test, tubing was heated to 90°C under 8 MPa pressure for weeks. The tubing slowly changed over time. Another test showed that higher heat lowered the tubing's softening temperature. These results show why you need tubing that fits your environment.

Performance needs (durability, precision, and pushability)

Polyimide tubing is strong, precise, and easy to push. It keeps its shape even under stress. This makes it great for small, detailed jobs. For example, PI Glide™ tubing is slippery inside. This helps tools like catheters slide in with less force.

The tubing is precise enough for tiny medical tasks. It also resists wear and tear, like PEEK material. These features make it last longer. Polyimide tubing is a top choice for tough jobs.

Industry-specific requirements (medical, aerospace, electronics)

Polyimide tubing is perfect for medical, aerospace, and electronics jobs. In medicine, it is safe and flexible for tools like catheters. It handles high heat during cleaning without breaking.

In aerospace, it is tough and works in extreme conditions. It is used in wiring and other important parts. For electronics, it insulates well and resists heat. This makes it great for wires and connectors.

Many industries trust polyimide tubing because it is reliable. Whether for medical tools, planes, or electronics, it works well and lasts long.

Benefits of Low-Friction Coatings for Polyimide Tubing

How low-friction coatings improve performance

Low-friction coatings help polyimide tubing work better. These coatings lower friction, making tools move smoothly. In medicine, coated tubing helps catheters slide easily. This reduces harm to nearby tissues. In electronics, coatings stop damage from repeated movements. This makes parts last longer.

The smooth surface also saves energy. This is very useful in industries like aerospace. Less friction keeps the tubing strong and working well. Even in tough conditions, it performs reliably. Low-friction coatings make polyimide tubing a great choice for hard jobs.

Types of low-friction coatings for polyimide tubing
