Material Notes:

Natural Rubber, 45-55 °IRHD. Formulated to Defence Standard 93-30, Type QX, Grade 50 (NRQX50).Applications: Natural rubber offers low compression set, high tensile strength, high resilience and excellent resistance to tear and abrasion. The designation `Type QX` indicates that the material is suitable for certain applications where a high degree of compatibility with explosives is a requirement. However, compatibility with all explosives in all environments has not been established and design authorities should seek advice on particular applications from the Director, Defence Research Agency (Military Division), Fort Halstead, Sevenoaks, Kent, TN14 7BP.
