Modification of mineral fillers with amino-functional derivatives

Fillers playa major role in the rubber industry with respect to their effect on properties of vulcanised rubber and the compound's cost. For most applications rubber compounds are loaded with reinforcing carbon black fillers to increase hardness, stiffness, strength, resistance to tear and abrasion. Approximately 90% of the world's carbon black production is consumed by rubber industries. Carbon blacks are imported to Sri Lanka and in spite of high cost are not easily available in the local market
