Végétalex and TPU Inner Tubes: A Sustainable and High-Performance Combination

For cyclists seeking an eco-friendly yet highly effective tyre sealant, Végétalex by Effetto Mariposa stands out as a top choice. Its biodegradable, plastic-free formula makes it an environmentally responsible alternative while ensuring excellent puncture protection. 
One of the most common questions among cyclists these days is whether Végétalex is compatible with TPU (thermoplastic polyurethane) inner tubes. The answer? Yes, absolutely.

Why Choose Végétalex for TPU Inner Tubes?

Unlike traditional latex-based sealants, Végétalex utilizes a plant-based formula that includes finely ground olive stones and cellulose fibers. These elements create an efficient puncture-sealing mechanism without relying on natural or synthetic latex and without any chemical reaction affecting TPU. The extended durability of Végétalex is another big plus over latex sealants, that can solidify in a matter of some months and create big, solid clumps.
As a result, TPU inner tube users choosing Végétalex can benefit from:

• Full Compatibility: Végétalex works seamlessly with TPU inner tubes, providing an effective seal without affecting the material.

• Sustainability: its biodegradable and plastic-free composition make Végétalex an environmentally conscious choice.

• Long-Lasting Performance: with an extended lifespan inside the inner tube, Végétalex remains active much longer than latex sealants, keeping the inner tube functional.

How Much Végétalex for a 28 mm Road Bike Tyre?

For optimal performance, Effetto Mariposa recommends using approximately 40 ml of Végétalex for a TPU inner tube inside a 28 mm road bike tyre. This quantity ensures sufficient coverage and puncture protection without adding unnecessary weight.

Can Végétalex Handle High Pressures?

Even if pressures are not as high as some years ago - when most cyclists were riding on 23 mm tyres inflated at 8 bar - road cyclists still ride at pressures typically around 6 bar (87 psi) or more. Végétalex performs effectively even under these conditions. However, the sealing process depends on the puncture size: the larger the hole, the lower the pressure at which the seal will occur. Nevertheless, Végétalex maintains its efficiency, making it a reliable choice for high-pressure applications.

Final Thoughts

Végétalex is a perfect option for TPU inner tube users looking for a high-performance, sustainable sealant. With its plant-based formula, compatibility with high pressures, and long-lasting durability, it provides an excellent balance of puncture protection and environmental responsibility. Whether you're an eco-conscious road cyclist or simply seeking a hassle-free solution, Végétalex delivers on all fronts.
