GENERAL INFORMATION The information given below is provided for clarification and assistance in meeting the requirements of this specification. 5.1 Material Background This material was developed to eliminate field problems associated with ESB-M4D233-A foam padding collapse, and to reduce permanent compression set caused by ski rack loading. In addition, this material eliminates the need for polyester sheeting which currently backs the ESB-M4D233-A foam padding to maintain its shape during installation.
