Maleid's application F allows to solve problems of high-temperature curing, allowing unlike sulfuric, to conduct curing of rubbers of general purpose at a temperature of 183 °C practically without reversion and to receive rubbers with good physical and chemical properties.
Maleid F increases communication durability the rezinokordnykh of systems for 20%, increases resistance of rubber mixes to premature curing and heat stability of vulcanizers.
Maleid F by efficiency of action and physical and chemical properties is at the level of the best world analogs.
Maleid F allows to receive rubbers with a high fatigue durability, especially after thermal aging.
Represents the composition consisting of 75% of N, N-metafenilendiamina and 25% of binding additives.
Maleid F receive acylation of a metaphenylenediamine maleic anhydride in the presence of acetic anhydride and the catalyst among the organic solvent with the subsequent filtering, entering of additives, a granulation and drying.
