The Breakthrough of Polyether Ester Defoamers: How Chemi Tech Conquers High-Temperature Foam

The Phantom Foam in Production Lines

At a precision metalworking shop in Guangdong, Manager Zhou faced a bizarre phenomenon - whenever machines reached full speed, the cutting fluid tank would erupt with foam like overflowing beer.

"Foam carried metal debris everywhere, contaminating equipment and causing 30% workpieces to fail quality checks." Zhou explained. They doubled traditional defoamer dosage, but foam worsened at high temperatures.

Molecular Engineering Solution

Chemi Tech's field tests revealed two critical challenges:

"Conventional defoamer molecules break down under such conditions." The R&D head demonstrated comparative tests: while standard products lost 80% effectiveness at 60℃, Chemi-Tech 7300 with its star-shaped molecular structure:

Hidden Cost Savings

After three months, the shop reported:
✓ Extended cleaning cycles by 2X (less foam reduces contamination)
✓ 40% reduction in cutting fluid replacement
✓ Annual waste treatment savings exceeding $17,000

"Now our German CNC machines finally perform at full capacity." Zhou proudly displayed bearing samples with improved surface finish during our follow-up visit.
