TPU medical pad: the art of drying and improvement of quality

In the medical pad market that pursues high quality and excellent performance, thermoplastic polyurethane (TPU), as a high-performance material, is gradually becoming the industry leader. However, to fully realize the potential of TPU in medical pads, a link that cannot be ignored is the drying of raw materials. The carefully designed drying process can not only significantly improve the processing performance of TPU raw materials, but also bring higher yields and better quality characteristics to medical pads.

Although TPU material has many advantages, its hygroscopicity is a challenge that cannot be ignored. TPU raw materials that are not fully dried will form bubbles due to water evaporation during processing, seriously affecting the appearance and performance of the product. Therefore, drying treatment has become an important process in the production process of TPU medical pads. By precisely controlling the drying temperature, time and environment, the moisture in the raw materials can be effectively removed and the TPU particles can reach the ideal dry state.

When TPU raw materials are fully dried, their melt flow properties during processing will be significantly improved. This means that in processes such as injection molding, molding or thermoforming, TPU can fill the mold more evenly, reducing defects and bubbles caused by poor flow. This not only improves the yield of medical pads, but also ensures the flatness and consistency of product appearance.

In addition to improving processing properties, the drying treatment also has a positive impact on the mechanical properties of the TPU material. Moisture is the "invisible killer" in plastic materials. It weakens the binding force between molecules and reduces the strength and toughness of the material. Therefore, the TPU raw material after removing moisture can more fully exert its mechanical property potential during processing.

Specifically, the TPU medical pad after drying has excellent performance in terms of tensile strength, elongation at break and wear resistance. This means that the medical pad can withstand greater pressure and deformation during use without being easily damaged, while maintaining good resilience and durability. For patients who need to stay in bed for a long time, such medical mats can provide a more stable and comfortable support environment, helping to reduce physical fatigue and discomfort.

In the medical field, product quality and safety are always the primary considerations. After undergoing strict drying and fine processing techniques, TPU medical pads not only have significantly improved quality, but also meet the strict requirements of medical-grade products. Every aspect from the selection of raw materials to the production process has been carefully designed and strictly controlled to ensure the biocompatibility, non-toxicity and environmental protection of the product.

In addition, the drying process also helps to remove harmful substances such as volatile organic compounds and impurities in TPU raw materials, further improving the safety and reliability of medical pads. This is especially important for patients who require special care, providing them with a safer and healthier recovery environment.

Drying treatment is an indispensable part of the production process of TPU medical pads. It can not only improve the processing performance and mechanical properties of raw materials, but also ensure the quality and safety of products. With the continuous advancement of medical technology and people's growing needs for health, TPU medical pads will play an important role in more fields. In the future, we have reason to believe that through continuous technological innovation and quality improvement, TPU medical pads will bring patients a more comfortable, safe and efficient rehabilitation experience.
