Eco-minded adhesive for rubber reinforcing fiber
Resorcinol-formaldehyde latex (RFL) adhesives have long been used to reinforce rubber products, such as tires, with fiber to maintain strength and morphological stability. In recent years, however, demands have been growing for solutions that do not use RF, which has been shown to have harmful effects on the human body.
The new adhesive uses a non-RF blended polymer for bonding. The polymer, which is reticulated by intermolecular interaction, achieves a high level of adhesiveness, equivalent to that of an RFL adhesive thanks to its high affinity for both fiber and rubber.
