I. Industry Challenges: Environmental Compliance and Precision Control
The medical materials industry faces strict regulatory requirements and increasing technical challenges. Traditional polymer materials often struggle with residual solvents, VOC emissions, and other environmental compliance issues. At the same time, manual or semi-automated production leads to variations in product quality—especially in high-end applications such as implantable medical devices and advanced wound dressings where precision and consistency are critical.
Polyurethane foam has emerged as an ideal alternative to conventional rubber and silicone, thanks to its biocompatibility, controllable pore structure, and eco-friendly manufacturing process. To fully unlock this potential, Feilong’s new series of eco-friendly polyurethane foam equipment offers a complete solution for high-precision, large-scale medical material production, driving the industry toward smart manufacturing and sustainable development.
