Where does the name "Para Rubber" come from?


Just look at a parachutist. Its control cords are attached to the parachute via a ring and para rubber loops. At the time, a special rubber was developed for this life-threatening application, which is highly resistant to tearing and is also elastic. Soon the name "Para Rubber" was born.
