A recurring challenge in plastics exposed to the sun
When plastics used outdoors are exposed to solar radiation, surface temperature can increase significantly in a short time. This phenomenon, common in applications such as window profiles, facades, or structural components, compromises dimensional stability, functionality, and ultimately, the product’s lifespan.
Under extreme conditions, temperatures may exceed 80°C, especially in dark-colored plastics, due to their high absorption of infrared radiation. This thermal stress can cause deformation, loss of mechanical properties, and increased maintenance or replacement costs.
Delta Tecnic’s solution: customized cool pigments
To address this challenge, Delta Tecnic has developed a differential proposal based on its extensive experience in masterbatch formulation and functional pigments. Thanks to advanced selection of cool pigments, it is possible to:
- Reduce thermal increase in sun-exposed plastics by up to 30%.
- Maintain vibrant colors without sacrificing thermal stability.
- Extend the lifespan of exposed products.
Unlike traditional solutions that limit the color range to light shades, Delta Tecnic’s cool pigments allow for customized designs without compromising durability.
Proprietary technology and advanced testing
The development of these formulations is supported by rigorous Build Up Tests conducted in Delta Tecnic’s own laboratory. In these tests, samples are subjected to controlled infrared radiation, simulating real solar exposure while precisely monitoring temperature changes.
This methodology allows:
- Validation of the thermal behavior of each formulation.
- Comparison of performance against standard alternatives.
- Adjustment of the solution according to each client’s technical and economic requirements.
In addition, Delta Tecnic strategically combines cool and conventional pigments to optimize both performance and final formulation cost.
Economic and sustainable impact
The cool pigment technology not only improves technical performance but also helps to:
- Reduce production costs by up to 30% at equal performance levels.
- Minimize the need for replacements or repairs due to thermal failures.
- Promote more responsible use of resources and energy.
By expanding color design options for outdoor applications, new opportunities open up for manufacturers seeking to differentiate their products in increasingly competitive and demanding markets.
Leadership and continuous innovation
With over four decades of experience, Delta Tecnic remains firmly committed to innovation, offering customized solutions on a global scale. Its combination of technical knowledge, in-house R&D infrastructure, and extensive network of international suppliers positions the company as a leader in functional pigments for the plastics sector.
Each project is approached individually, working closely with the client from the reception of the colorless base compound to the final validation of the formulation under real exposure conditions.
