1. The liner is made of modified polytetrafluoroethylene (TFM), PFA and PTFE materials;

2. High-purity material, no recycled materials, clean processing environment, optimized processing technology, ensuring extremely low background;

3. TFM is resistant to high and low temperature -200～+260℃, has the characteristics of extremely low blank value, better deformation resistance, penetration resistance, and stronger recovery under high temperature and high pressure;

4. The experimental data is no less than that of the original factory, and the price is favorable, which greatly reduces the cost of purchasing consumables for many scientific research institutions;

5. The production process specially developed by our factory reproduces the finish of the super long inner vessel of a special manufacturer (such as CEM);

6. The liner can be matched with our graphite electric heating plate as the acid-removing equipment in the later stage of the experiment.
