Why is natural rubber a strategic material?

Answer:

Standard rubber: standard rubber is mainly divided into 5 glue, No. 10 glue and No. 20 glue. Glue No. 5 is the first grade glue. It is the best glue. Its impurity is 0.05%; No. 10 glue is two grade glue, its impurity is 0.10%, 20 glue is three glue, and its impurity is 0.20%. Glue uses different models are not the same: No. 5 commonly used to make rubber tyres; No. 10 and No. 20 rubber glue for making tire.Smoke film: the natural film pressure to the water were smoked after baking film by burning the coconut shell by smoke and heat. The purpose of fumigation is to make the film dry and inject anti oxidation and antiseptic cresol substances. Natural rubber is the primary form of smoke film.Concentrated adhesive: it can be used as bonding material.
Natural rubber can be divided into standard rubber (also called rubber), smoked rubber sheet, concentrated gum, white crepe, light colored film, skim rubber and dry film, is the most commonly used standard rubber and smoke film. Standard rubber is divided into a (SCR5), two (SCR10), three (SCR20), four (SCR50) four grades, divided into 1-5 smoke smoke film (RSS1-RSS5) five grades.
Rubber is an important strategic material, in the national defence application is very extensive, for example, a tank with more than 800 kg of general rubber; thirty thousand ton warship with sixty-eight tons of rubber, military equipment, air force facilities, almost all defense engineering rubber footprint. The use of rubber made ship, tent, warehouse and protective equipment, clothing etc. there are many varieties of bath water. As for the anti - tip technology needs high temperature, low temperature, oil resistance, high vacuum resistance and other special properties of the rubber, the constitution of 0 products is indispensable. With the development of national defense modernization, rubber, which is capable of resisting the temperature range of minus 100-400 DEG C and capable of resisting various acids, bases and oxidants with special properties, is being developed and manufactured.
