Bluestar Silicones was contacted by a manufacturer of radial tires for passenger cars and was asked to provide a durable multi-release agent that would provide long-term release performance and bladder protection to ensure productivity, tire quality and durable bladder life.
The requirements included the following quality and process improvement items:
Improved tire quality, through the elimination of dirty tire aspect, coming from high amounts of heavily filled inside paints that create mold pollution
Reliable release performance to avoid imperfections caused by non-homogeneous release behavior
Reduced defect rates through improved air evacuation and bladder centering during bladder inflation and optimal post cure release performance
Increased bladder life by protecting the bladder against abrasion, sulfur migration and oxidation
A decrease in manpower requirements by reducing labor-intensive steps in the production process
Lower total costs based on the use of lower volumes of release agents.
