Precision-engineered TPU pneumatic solutions, ultra-light bicycle inner tubes, and high-tenacity industrial hoses
As Barcelona and the wider Catalonia region accelerate their transformation into Southern Europe’s premier hub for sustainable urban mobility and high-tech industrial automation, the demand for advanced material science in pneumatic applications has reached an all-time high. Traditional vulcanized butyl rubber inner tubes and standardized rubber hoses are increasingly proving to be technological bottlenecks. Modern municipal transport projects, such as Barcelona's ambitious Superilles (Superblocks) urban design initiative and the expanding Carril Bici bicycle lane network, require micro-mobility components that minimize downtime, reduce system weight, and withstand harsh coastal environmental stressors.
Our OEM manufacturing unit specializes in custom thermoplastic polyurethane (TPU) extrusion and conversion. Unlike standard butyl, which suffers from low tensile strength, rapid air permeability, and weight penalties, our proprietary ultralight TPU formulations deliver up to a 75% mass reduction while doubling puncture resistance against sharp urban debris like glass, thorns, and metallic shards. For commercial bike-sharing operators, OEM bicycle brands based in Spain, and industrial equipment integrators across the Zona Franca and Martorell industrial belts, our customized TPU tubing delivers unprecedented operational efficiency and total cost of ownership (TCO) savings.
Furthermore, Barcelona's coastal Mediterranean climate presents unique challenges. High humidity, elevated salt-spray levels from the Mediterranean Sea, and intense summer UV radiation accelerate the degradation of classic rubber hoses and tubes, leading to premature cracking and dry rot. Our 100% pure ester- and ether-based TPU materials demonstrate superior hydrolytic stability, UV resistance, and chemical inertness, making them the ultimate material choice for both high-end cycling and industrial fluid transfer in coastal Southern Europe.
To understand why global OEMs are shifting to Thermoplastic Polyurethane, one must examine the molecular architecture of the polymers. Butyl rubber relies on vulcanization—a chemical cross-linking process using sulfur that creates a dense, heavy matrix susceptible to shear breakdown over time. TPU, by contrast, is a block copolymer consisting of alternating hard and soft segments. This unique structural composition provides an extraordinary combination of high elasticity, extreme tensile strength, and exceptional tear propagation resistance.
Wall thickness can be safely reduced to an astounding 0.15mm – 0.3mm (compared to 0.9mm for standard butyl) without compromising pressure retention or mechanical integrity, cutting inner tube mass down to just 23g–38g.
Exhibits tensile strength exceeding 45 MPa and elongation at break over 550%. TPU stretches around intruding sharp objects rather than puncturing under pressure, preventing catastrophic blowouts.
Uninflated TPU inner tubes occupy up to 70% less physical volume than butyl equivalents, allowing bike shops, fleet maintenance hubs, and cyclists to store multiple spare tubes in minimal space.
Our OEM ultralight tubes and customized TPU hoses are tailored to meet the exacting requirements of specific regional applications across Catalonia’s diverse geographic and industrial landscapes:
Navigating Barcelona’s dense urban core, from Eixample to Poble Sec, requires high uptime. Our anti-puncture TPU liners and heavy-duty X-TUBO series drastically reduce maintenance intervals for e-bikes, urban cargo bikes, and municipal rental fleets.
The rugged terrain of Parc Natural de Collserola presents demanding gravel and trail conditions. Our Tubo-CX/Gravel and S-TUBO MTB series feature high pinch-flat resistance, permitting lower tire pressures for enhanced traction without snakebite risk.
Road cyclists tackling iconic climbs like Santa Fe del Montseny or coastal routes along the Costa Brava benefit from ultra-low rolling resistance and 30g lightweight wheel setups, maximizing watt efficiency on long alpine gradients.
Catalonia's automotive and manufacturing facilities require reliable pneumatic transmission lines. Our 4mm-16mm PU air hoses and ester-based PUR tubing ensure zero-leak fluid transfer, kink resistance, and high burst pressure tolerance.
Specialized flexible TPU riser pipes and food-grade transparent coils meet strict EU food-contact standards, delivering safe drinking water transfer for coastal resorts, agricultural irrigation, and maritime operations.
Tailored specifically for compact folding bikes (such as Brompton-style 16" rim setups), our Tubo-Folding range provides lightweight, pocket-sized spare solutions for intermodal public transit commuters across BCN.
Below is an engineering datasheet outlining key physical attributes across our standard and custom OEM TPU tube product lines:

The European Union’s stringent environmental regulations, including REACH compliance and the European Green Deal objectives, are reshaping procurement requirements for bicycle OEMs and industrial distributors in Spain. Traditional butyl rubber presents severe recycling challenges; vulcanized rubber cannot be remelted easily and often ends up in landfills or incineration plants. In contrast, our TPU tubes and hoses are 100% thermoplastic, meaning they can be fully melted down, re-granulated, and recycled into new technical polymer products without toxic emissions.
Catalonia's forward-thinking urban policies are driving rapid adoption of micro-mobility vehicles. As Barcelona expands its low-emission zones (Zona d'Espais Ambientals), commercial delivery companies are replacing diesel vans with heavy-duty e-cargo trikes. These heavy vehicles put immense pressure on wheels, leading to high blowout rates with normal inner tubes. By integrating custom OEM TPU inner tubes engineered with double-layer sidewalls, fleet operators reduce tire-related downtime by over 60%, supporting the city's goal of clean, continuous urban logistics.
As a specialized OEM/ODM manufacturer and global exporter, we partner with bicycle brands, private label distributors, and industrial supply houses across Europe to deliver fully customized solutions. Our production facility operates under strict ISO 9001:2015 quality management standards, offering bespoke capabilities including:
Our export division handles complete HS Code classification (e.g., HS Code 4013.90 for bicycle inner tubes / HS Code 3917.31 for plastic tubing), providing all necessary EU compliance certificates, Certificates of Origin (Form A / EUR.1), commercial invoices, and packing lists to ensure seamless clearance through Barcelona Customs (Aduana de Barcelona).
While standard TPU tubes perform exceptionally well with disc brakes, extreme friction heat from rim brakes on long alpine descents can exceed thermal limits. For rim brake applications, we recommend our thermal-stabilized Tubo-Road series or specifying disc-brake-only setups for ultra-lightweight S-TUBO models (23g) to ensure maximum safety.
TPU requires a dedicated solvent-based adhesive or specialized self-adhesive TPU patches (such as the Tubolito patch kit). Standard rubber patches and vulcanizing vulcanizing fluid will not bond with TPU polymer. We supply custom white-label TPU repair patch kits for OEM clients to include with their packaged products.
Our standard OEM sample trial orders start as low as 500 units for stock dimensions. For custom color extrusions, specialized valve colors, or bespoke retail packaging tailored for the Spanish market, our standard production MOQ is typically 1,000 to 3,000 units per specification.
Standard sea freight shipments to the Port of Barcelona take approximately 22 to 28 days. Air freight express options directly to Barcelona-El Prat Airport (BCN) are available for urgent sample validation or high-demand seasonal restocking, arriving within 5 to 7 business days.
Yes. Our ester and polyether-based polyurethane hoses are specifically formulated with hydrolysis-resistant additives, ensuring zero degradation when exposed to marine salt spray, ambient moisture, or airborne chemical contaminants common along the Mediterranean coast.
