Single-ply roofing is enjoying an increasingly larger share of the commercial and industrial roofing industry. The hottest item in the single-ply market is ethylene propylene dicnc monomer (EPDM). Long term dependability, weatherability, and durability are among the primary factors contributing to the rapidly increasing demand for EPDM roofs.

Royal Edge EPDM has many properties superior to other commonly used elastomers. The table below shows this comparison with SBR, natural rubber and other polymers. Vulcanizates of Royal Edge EPDM exhibit many outstanding properties.

Lower Specific Gravity

The specific gravity of Royal Edge EPDM is lower than all other rubbers. Consequently, EPDM offers a higher yield of fabricated parts per pound. Final product also benefits by the ability of Royal Edge EPDM to be highly extended with inexpensive oils and carbon blacks. Royal Edge EPDM can accept larger amounts of fillers than other rubbers with good retention of physical properties.

Retains Properties at High Temperatures

Royal Edge EPDM is serviceable for extended periods of continuous use at temperatures in excess of 300 F and has shown good results in intermittent uses as high as 400F.
Such vital properties as resilience, tensile strength, elongation and hardness are largely retained in aging test at elevated temperatures. Royal Edge EPDM is far superior to any other general purpose synthetic rubber on high temperature resistance.

Retains Properties at Low Temperatures

Royal Edge EPDM retains its flexibility at extremes that shatter most rubber materials. Royal Edge EPDM compound remains serviceable at temperatures as low as -70F.

Other Benefits

Other benefits of Royal Edge EPDM are excellent processing, good to excellent physical properties, excellent weather and ozone resistance, excellent electrical properties and excellent resistance to polar liquids such as waters, phosphate esters ketones.
