RFL Fiber Bonding Agent (Resorcinol-Formaldehyde-Latex)
RFL (Resorcinol-Formaldehyde-Latex) dip is the industry standard adhesive system for bonding textile tire cords (nylon, polyester, rayon, aramid) to rubber compounds. The dip consists of a resorcinol-formaldehyde resin precondensate dispersed in rubber latex (typically VP latex), which when applied to the cord and heat-cured, forms a strong interfacial bond between the cord and rubber matrix. RFL systems are critical to tire durability, ensuring the cord-rubber composite maintains integrity under dynamic flex conditions.
