Understanding TPU Inner Tubes

Thermoplastic Polyurethane (TPU) is a versatile material that combines the elasticity of rubber with the toughness and durability of plastic. This unique combination makes TPU an ideal material for bicycle inner tubes.

Advantages of TPU Inner Tubes:

• Lightweight: TPU tubes are significantly lighter than traditional butyl tubes, reducing the overall weight of the bicycle and enhancing performance.
  

• Durability: TPU offers high resistance to abrasion, cuts, and punctures, ensuring a longer lifespan for the inner tubes.
  

• Flexibility: The material's flexibility allows it to conform to the tyre's shape, providing a smoother ride.
  

• Recyclability: TPU is a recyclable material, aligning with environmentally conscious practices.
  

At Eclipse TPU, we pioneered the development of TPU inner tubes in 2011, introducing the world's first commercial TPU inner tube. Our tubes are designed with precision, utilising advanced manufacturing techniques to ensure consistency and reliability.

We are committed to sustainability, and our TPU inner tubes are fully recyclable. By choosing Eclipse TPU inner tubes, cyclists contribute to reducing environmental impact while enjoying superior performance.

Common Causes of Punctures in TPU Tubes

While TPU inner tubes are more resistant to punctures than traditional butyl tubes, they are not entirely immune. Understanding common causes of punctures can help in prevention and timely repairs.

Common Causes:

• Sharp Debris: Objects like glass shards, nails, or thorns can penetrate the tyre and puncture the inner tube.
  

• Pinch Flats: Also known as "snake bites," these occur when the tyre compresses against the rim, causing the tube to be pinched and punctured.
  

• Prolonged Wear: Over time, the inner tube material can degrade, making it more susceptible to punctures.
  

• Improper Installation: Incorrect installation can lead to folds or twists in the tube, increasing the risk of punctures.
  

Regular maintenance and inspection of tyres and inner tubes can help in early detection of potential issues. Using protective measures, such as tyre liners or sealants, can also reduce the likelihood of punctures.

The compact size of the kit makes it convenient to carry during rides, ensuring you're prepared for unexpected punctures.

Eclipse TPU Tube Sealant

Our TPU Tube Sealant is a solvent-free, fast-reacting solution designed to seal punctures efficiently.

Features:

• Quick Sealing: The sealant rapidly seals punctures, reducing air loss and maintaining tyre pressure.
  

• Solvent-Free Formula: Safe for TPU materials, ensuring no degradation of the inner tube.
  

• Enhanced Air Retention: Improves the already superior air retention properties of TPU tubes.
  

• Compatibility: Suitable for all TPU inner tubes available in the market.
  

Usage Recommendation:

• Volume: Use an amount equivalent to the tyre width in millimetres (e.g., 25ml for a 25mm tyre).
  

• Application: Shake well before use and inject into the inner tube through the valve.
  

By incorporating our sealant, cyclists can proactively prevent punctures and maintain optimal tyre performance.

Step-by-Step Guide to Repairing TPU Tubes

Repairing TPU inner tubes is straightforward with the right tools and techniques. Below is a step-by-step guide using Eclipse TPU's repair solutions.

Using the Adhesive Repair Patch Kit

• Locate the Puncture:
  

• Inflate the inner tube and listen for escaping air or submerge it in water to identify bubbles.
  

• Prepare the Area:
  

• Deflate the tube completely.
  

• Clean the puncture area using the provided alcohol prep pad to remove dirt and oils.
  

• Ensure the area is dry before proceeding.
  

• Apply the Patch:
  

• Peel the backing off the patch.
  

• Place the patch directly over the puncture, pressing firmly to ensure full adhesion.
  

• Allow the patch to set for a few minutes.
  

• Reinflate and Test:
  

• Inflate the tube to the recommended pressure.
  

• Check for any air leaks to confirm the repair's success.

Applying the TPU Tube Sealant

• Prepare the Tube:
  

• Ensure the inner tube is deflated and removed from the tyre.
  

• Inject the Sealant:
  

• Shake the sealant bottle well.
  

• Remove the valve core if possible.
  

• Using an appropriate injector, introduce the recommended volume of sealant into the tube.
  

• Reinstall and Inflate:
  

• Reinstall the valve core.
  

• Place the tube back into the tyre and mount it onto the rim.
  

• Inflate the tyre to the desired pressure.
  

• Distribute the Sealant:
  

• Rotate and shake the wheel to evenly distribute the sealant inside the tube.
  

By following these steps, cyclists can efficiently repair punctures and extend the life of their TPU inner tubes.

Maintenance Tips to Prevent Future Punctures

Preventative maintenance is key to reducing the likelihood of punctures and ensuring the longevity of your TPU inner tubes.

Regular Inspections

• Check tyres and inner tubes for signs of wear, embedded debris, or damage.
  

• Ensure that the tyre tread is not excessively worn, which can increase the risk of punctures.

Proper Inflation

• Maintain the recommended tyre pressure to prevent pinch flats and improve ride quality.
  

• Use a reliable pressure gauge to monitor and adjust tyre pressure regularly.

Use of Sealant

• Consider adding Eclipse TPU Tube Sealant as a preventative measure, especially for long rides or rough terrains.
  

• The sealant can seal minor punctures as they occur, reducing the need for immediate repairs.

Carry Repair Kits

• Always have an Eclipse Adhesive Repair Patch Kit during rides to address unexpected punctures promptly.
  

• Familiarise yourself with the repair process to ensure quick and effective fixes when needed.
  

By implementing these maintenance practices, cyclists can enhance their riding experience and minimise disruptions caused by punctures.

Environmental and Economic Benefits of Repairing TPU Tubes
