Important update regarding PTCR ETH and ETL rings – New formulation from batch ETH 096

Current product information for users of PTCR ETH and ETL rings

If you are already using our ETH rings, we would like to inform you in good time of an important change that may affect your processes.

Background: Change to the formulation

The PTCR ETH and ETL rings, which we source through our partner Vibrantz Technologies, will be produced with a revised formulation from batch ETH 096 onwards.

The reason for this change is the discontinuation of a key raw material, which made it necessary to reformulate the product.

The good news:
The new formulation has been extensively tested and demonstrates comparable performance to the previous rings.

Impact on your processes

Despite the comparable performance, there are a few important points to note:

1. Slight change in shrinkage behavior

The new raw material may cause the shrinkage behaviour to change slightly.

This may lead to:

• process-dependent variations
• as well as a one-off, larger difference between old and new batches

process-dependent deviations.

2. Recommendation for recalibration

If your firing cycle differs from the calibration cycle, we recommend:

• Recalibration using old and new batches
• Determination of an individual correlation factor

This ensures that your measurement results remain accurate and reliable.

3. Possible color variations

Due to the adjusted formulation, minor color differences may occur:

• in the unfired state
• as well as in the fired state

These differences are material-related and do not affect the functionality of the rings.

Conclusion: What does this mean for you?

• Consistent performance despite the new formulation
• Minor process adjustments may be required
• Recalibration recommended for maximum accuracy

By providing this information at an early stage, we aim to give you sufficient time to plan for any necessary adjustments to your processes.
