Recommendations for achieving best Bladder Performance

CONTI BLADDERS are manufactured using a well proven longlasting butyl rubber compound.

The high degree of elasticity of the bladder guarantees trouble-free molding and stripping.

The following points should be considered under all circumstances:

1. The bladder must be warmed up (to approx. 40°C) before mounting.
2. Please follow press manual instructions for proper mounting.
3. Before tire curing starts, the bladder should be fully warmed up. For this, the machine should be operated according to the press manual.
4. In case of pre-inflating during the warm up, the bladder OD must not exceed the tire sidewall OD, in order to avoid non-symmetric deformation.
5. If the bladder has cooled down after an interruption in the curing process, it is imperative to warm it up again.
6. In case the curing medium (hot water or steam) is contaminated with too much oxygen, it should be neutralized by the addition of oxygen scavenger, in order to avoid deterioration of the bladder.
