フィルムの COF テストを理解する: 方法と基準
Understanding COF Testing for Films: Methods and Standards Introduction to COF Testing for Films The coefficient of friction (COF) is a critical parameter in material testing, especially for films used in packaging, medical devices, pharmaceuticals, adhesives, and textiles. COF testing measures the resistance encountered when two surfaces slide against each other, providing essential data for quality control, manufacturing optimization, and regulatory compliance. Understanding COF Testing COF testing is divided into two main types: Static COF: The force required to initiate movement between two surfaces. Kinetic COF: The force required to maintain movement between two surfaces. Both measurements are vital for ensuring the performance and usability of films in various applications. […]
