"PIOCELAN utilizes proprietary polymer hybrid technology, enabling the adjustment of various physical properties to meet a wide range of application requirements. We offer several product series, including the O series and S series. The O series is suitable for a variety of structural applications and provides excellent impact absorption performance. It is widely used in applications such as automotive impact energy absorbers. This series also includes the E type, featuring smaller bead sizes for molding complex foam part geometries, and the NS type, which offers permanent antistatic performance for electrostatic-sensitive applications such as electronic component transport containers. The S series is designed for protective packaging applications. It provides excellent cushioning performance while enabling material savings and cost reduction through higher expansion ratios.
For detailed information on each grade, please contact us. We will be pleased to recommend the most suitable PIOCELAN grade according to your specific requirements."
A highly versatile series offering an excellent balance of cushioning performance and impact resistance, with a proven track record in automotive component applications.
A series designed for further weight reduction through higher expansion ratios, providing superior cushioning performance compared with the O series.
