This apparatus will record the change in height with time to fully define how a viscoelastic foam responds to compression. The process generally includes compressing a compression plate against a surface of the viscoelastic foam sample from a nominal height to a pre-determined compressed height, maintaining the pre-determined compressed height for a period of time; retracting the compression plate at a rate greater than a recovery rate so as to disengage the compression plate from the viscoelastic foam sample, and measuring displacement as a function of time to provide a viscoelastic response profile. Measuring the displacement may be contact based or non-contact based."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus and process for measuring viscoelastic foam compression recovery","description":"An apparatus and process for measuring recovery rate and total recovery time of viscoelastic foam samples.
