The TA type was developed in 1940 and is made from natural rubber latex compound film which has a high elasticity modulus and also high tear resistance. Physical properties are retained at extremely low temperatures and the latex compound contains additives which contribute to its resistance to oxidation and ozone.
The robustness of the rubber film allows the fully gas inflated TA Type of balloon to retain its original spherical shape, making it particularly suitable for flight in severe weather conditions.
