Product Overview

CRL Thermoplastic Rubber (TPR) Setting Blocks are incredibly versatile and can be confidently used in designs requiring modern structural glazing sealants. Made of 90-durometer shore hardness thermoplastic rubber, these blocks perform just as effectively as traditional neoprene setting blocks. They are available in popular neoprene block sizes and offer outstanding chemical resistance without causing any damage to surfaces. It is strongly recommended to conduct job-specific testing with each silicone sealant manufacturer before starting the project.
