ELVALOY™ KEE (Ketone Ethylene Ester) Terpolymers

ELVALOY™ KEE (Ketone Ethylene Ester) Terpolymers

Sustainable flat roof

Solutions for next-generation roofing

Commercial buildings need durable and resilient roofing that can withstand torrential rain, searing heat, frigid cold, constant winds—and the test of time. Dow’s ELVALOY™ KEE (Ketone Ethylene Ester) Terpolymer delivers these properties and more.

Non-migrating

ELVALOY™ KEE is a non-migrating PVC plasticizer used for watertight, low-slope roofing. ELVALOY™ KEE makes PVC supple, pliable and durable. The non-liquid additive also eliminates plasticizer migration, which can cause resin to shrink, expand, crack and leach other chemicals.

For easy installation

A roofing membrane modified with ELVALOY™ KEE is light, easy to install and has a high tensile strength to resist breaking under pressure.

Temperature-resistant

ELVALOY™ KEE has a high tolerance for temperature swings. PVC roofing membranes modified with ELVALOY™ KEE are tolerant of temperatures ranging from minus 35 degrees Celsius (minus 31 degrees Fahrenheit) to 100 degrees Celsius (212 degrees Fahrenheit).

More attributes

ELVALOY™ KEE has many more attributes such as it is not a liquid plasticizer, it improves chemical resistance, and promotes flexibility and durability. ELVALOY™ KEE also eliminates plasticizer migration and increases tensile strength. ELVALOY™ KEE makes roof installation easier and more cost-effective. 

Roofing membranes created with ELVALOY™ KEE

Roofing membranes created with ELVALOY™ KEE last longer than the alternative and are not susceptible to microorganism (mold) growth, which eats away at plasticizers and eventually causes roofing to degrade and fail. Moreover, roofing membranes treated with cool reflective roof coatings can cut a building’s cooling bill by 20 percent.

Just one of Dow’s many revolutionary modifiers

ELVALOY™ KEE is part of Dow’s robust family of raw materials and resin products for various applications in addition to roofing, including automobiles, medical devices, wire and insulation, footwear and construction products.
