Process for introducing perforations into silicone gel laminate using ultrasonic energy
The granted patent (Publication Number: US11919190B2) discloses a process for introducing perforations into a laminate, involving steps such as providing a laminate with a substrate layer and a silicone gel layer, using an ultrasonic welding device to introduce perforations, and keeping the deformable layer in contact with the silicone gel layer for at least 12 hours after perforation. The process aims to create perforations in the substrate layer and silicone gel layer simultaneously, with deformed portions penetrating into the perforations, potentially useful in various applications.
Additionally, the patent claims specify various aspects of the process, including the type of substrate layer (polymer), its thickness (5 µm to 200 µm), the composition of the silicone gel layer (two-component silicone composition), and the characteristics of the perforations (diameter from 0.5 mm to 20 mm). The process also involves specific materials for the deformable layer (polypropylene, polyester, polycarbonate, polyamide), and a softness/penetration depth range for the silicone gel layer (3 mm to 20 mm). Furthermore, the process includes steps such as bringing the silicone gel into contact with the substrate layer before perforation, and removing the deformable layer after the 12-hour contact period. These detailed claims provide a comprehensive overview of the patented process for introducing perforations into laminates, highlighting its potential applications and specific parameters for implementation.
