BALLOONS HAVING IMPROVED RESISTANCE TO OXIDATION |
摘要 |
The oxidation resistance of elastomeric balloons made from natural rubber is greatly improved by coating the exterior of the balloon with a film of uncured elastomer, preferably neoprene. The uncured elastomer coating maintains the clarity of the inflated balloons. These balloons are particularly useful as containers for gifts or in balloon sculpture.
