Description

TYL- Cell 150 is closed cell polyethylene foam joint backup cord for use in expansion joints where a backup material is required to provide support for a joint sealant. It enables the correct width to depth ratio of the sealing slot to be obtained and provide a firm backing to ensure that sealants are forced against and wet the sides of the joint during application. It also functions as a bond breaker at the back of the seal preventing additional stress on the sealant during joint movement.
