Mold Release Agents for Tire Manufacturing

Chem-Trend Release Agents Help to Produce the Best Tires on and off the Road

The process of tire curing/vulcanization brings specific challenges that, unless overcome, can lead to defective finished tires and/or reduced production efficiency. Challenges such as:

  • Ensuring the tire curing bladder locates centrally within the uncured (green) tire during the critical shaping process at the beginning of the cure cycle, to ensure good tire uniformity.
  • Evacuating any air that becomes trapped between the tire inner liner and the bladder during the shaping process to eliminate the risk of trapped-air defects.
  • Optimizing air-bleed between the outside of the tire and the mold to ensure optimum rubber flow, which ensures sharp sidewall lettering and clean edges to tread blocks to provide optimum tire appearance and reduce “lightness” defects.
  • Releasing tires that have complicated tread patterns and sticky tread compounds, such as the new generation of winter tires.
  • Reducing the build-up of mold fouling on tire molds.
  • Optimizing cured tire appearance to help achieve maximum market acceptance of your brand – especially in the highly competitive world of ultra-high performance tires.
  • Reducing curing-related tire defect levels.
  • Minimizing curing press downtime.

As the leading supplier of release agents to the global tire industry Chem-Trend understands these challenges and is constantly working to develop innovative solutions to help our customers efficiently produce high quality tires.

Common Questions:

  • How can I increase bladder life?

    The life of tire curing bladders can be increased through the application of a curing bladder treatment, which helps to protect the bladder against chemical and abrasion attack throughout its service life. This type of attack is prevalent at the surface of the curing bladders that contacts with the beads of the tires being cured. Coatings can significantly help increase average bladder life. The choice of inside tire paint can also have a positive impact on the service life of curing bladders.

Common Questions:

  • How do I apply product to a green tire?

    Most products for the tire industry are developed for application to green tires using any of the following systems; spray gun, either automated, e.g. Ilmberger or Plummer units etc., or hand-held spray guns; paint brush; sponge or swab. The actual application technique(s) chosen by any given tire plant depends primarily on the equipment available and the logistics of the particular plant. Experienced release agent suppliers should be able to provide recommendations to improve and optimize application techniques where desired.
