Why Do Silicone Travel Bottles Fail During Transit? Reference Standard: ASTM D1693 (Standard Test Method for Environmental Stress-Cracking of Ethylene Plastics, adapted for elastomer chemical resistance) and ISO 9001:2015. Short Answer Silicone travel bottles fail due to dynamic harmonic decoupling at the rigid-flexible interface caused by aircraft vibrations, leading to creep leakage. Additionally, unintended plasticization of the polysiloxane matrix by cosmetic lipids and Van der Waals force-driven particulate anchoring compromise both the structural integrity and surface cleanliness of the container. Dynamic Harmonic Decoupling and Creep Leakage at Rigid-Flexible Boundaries The failure of a leak-proof silicone cosmetic containers during flight is rarely a simple case of “air pressure bursting the cap.” … 続きを読む
