About Sealant Flexibility
More
Sealants
These sealants are non-sagging, so they won't drip from vertical and overhead surfaces.
Elongation and joint compression/expansion tolerance indicate flexibility. For joints between dissimilar materials and in environments with wide temperature fluctuation, choose a sealant with a higher elongation or joint compression/expansion tolerance. For high-wear applications, choose a harder sealant for the most abrasion resistance.

Puncture-Resistant Sealants
Form seals that resist punctures, cuts, and abrasion to withstand heavy wear and tampering. These sealants are non-sagging, so they won't drip from vertical and overhead surfaces.
Elongation and joint compression/expansion tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain. These sealants are best suited to joints between similar materials that aren't exposed to wide temperature fluctuation.
