RUBBER COMPOUND HA 1824 FOR AIRBORNE APPLICATIONS

摘要

The supply of imported rubber compound is not consistent due to high lead time & less shelf life of rubber compound (i. e. 3 months). In order to meet the production requirement the nitrile rubber compound HA 1824 was developed in-house. The developed rubber compound HA1824 is used at HAL, Nasik Division for manufacture of rubber seals and rubber bonded valves used in Brake units (Part No.s KT92D & KT92B) & other assemblies of fighter aircraft. The rubber compound HA1824 was developed in-house to comply airworthiness requirements. Accordingly Test Schedule was prepared considering the various aspects of end use. The physico-mechamcal properties were tested in Central Laboratory, HAL, Nasik Division and found satisfactory for airborne use. The functional test was carried out on the Brake unit assembly & found satisfactory.
