Alternatively, the first and second layers are defined by their shrinkage properties after 15 minutes at 200° C.: the first layer has shrinkage of more than 10% in at least one direction, and the second layer has shrinkage of less than 10% in the longitudinal and transverse directions. A laminate constructed in this manner exhibits lower fold formation when processed using multi-cavity thermoforming. The laminates are useful for the production of membranes for electroacoustic transducers."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Asymmetrical multi-layered membrane for electroacoustic transducers","description":"A multi-layered laminate for producing membranes for electroacoustic transducers, comprises a first layer of a polyether ether ketone film having a heat of crystallisation of at least 15 J/g, a second","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9796160","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
