Rhenosin® RB

Technical DataSheet | Supplied by Lanxess

Phenol formaldehyde resin. Acts as a hardening agent. Contains no externally added hardeners. Significantly increases the hardness of vulcanizates. Tensile strength is slightly reduced and elongation at break increased by the hardener system. Modulus is also increased, except in SBR. It does not affect scorch and vulcanization characteristics. Compatible with NR, SBR, BR, NBR and EPDM. It is not suitable for use in CR. It increases mix viscosity in NR, SBR, BR, EPDM and decreases in NBR. Recommended for for hard and very hard vulcanizates such as apex compounds in radial tires, floor coverings, paper rollers, heels, soling sheets, oil-resistant seals, brake linings, solid hose material. The dosage rate is 5-25 phr. To be fully effective, approx. 10 % hardener (Rhenogran Hexa 80) should be added.
