Elastomers are polymers (see below) which are elastic, that is they move with the fiber like a rubber band expands and contracts. All Nikwax polymers are also elastic. These elastomers provide increased performance.

(n) A special class of polymers that can withstand elastic deformation, then return to their original shape and size. Natural rubber, polyacrylate, ethylene propylene, neoprene, polysulfide, silicone, and urethane are types of elastomers.

Resilient materials having elastic properties (rubber, synthetic rubber or plastics).

This is the largest and most common class of materials used to modify asphalt. Included in this group are SBR & Natural Latex, Styrene/Butadiene block and di-block copolymers, polychloroprene and polybutadiene.

Synthetic polymers having properties of natural rubber such as stretchability and recovery.

Polymers that, when undergoing deformation, resist and recover in a way similar to that of natural rubber.
