Bubbles in FEP products
Problem Phenomenon
Bubbles appear in FEP products
Cause Analysis
Trace moisture or oligomers in FEP pellets gasify at the processing temperature
Solution
Strict drying (attention is still needed although the water absorption rate is extremely low); lower the processing temperature
Key Takeaway
Even extremely trace amounts of volatiles in FEP may cause bubbles at high temperatures
