Chemical Resistant Waterstop
Westec TPE-R® Waterstops
WESTEC's Envirostop™ TPE-R (Thermoplastic Elastomeric Rubber) 600 Series Waterstops resist a wide range of oils, solvents and aggressive chemicals and are not readily soluble in any common solvent. Alcohols, ketones, glycols, esters and aqueous solutions of acids, bases and salts have little effect on WESTEC TPE-R Waterstop. TPE-R will swell in aromatic solvents, halogenated organic solvents and hot petroleum oils. Featuring excellent ozone resistance, low temperature flexibility and excellent high temperature (up to 257° F) performance. Our synthetic rubber is heat weldable for easier and higher quality field splicing.
Westec PE (Polyethylene) Waterstops
WESTEC's Polyethylene Waterstop is an excellent alternative in an industrial, commercial or roadway application with chemical exposure to hydrocarbons, acids or bases. It is resistance to a wide range of chemicals including hydrofluoric acid. Featuring excellent environmental stress crack resistance and flexibility (flex fatigue), with no failure after one million cycles. WESTEC PE waterstop also has very good low temperature resistance.
