HIGH PURITY CERAMER FOR SEMICONDUCTOR APPLICATIONS
The extraction values of high purity Ceramer 20 parts are substantially lower than those of standard PTFE. They are comparable to high purity PFA.
High purity Ceramer 20 is, therefore, very suitable for applications in the semiconductor industry.
Water absorption of consolidated neat shapes of Ceramer was measured according to ISO 62. The weight gain at 23 °C is 0.1% after 24h and 0.4% when equilibrated.
Extraction values of parts made from specially produced high purity grade Ceramer 20, compared to standard PTFE and a high purity grade PFA. Determination followed an extraction test
(2% high purity grade nitric acid, 48 h, ambient temperature).
