Product Introduction

Raw Materials: Modified PTFE resin as the base material, with glass knitted fabric as the backing. Modified PTFE has 40% improved melt fluidity, making it easier to penetrate into the three-dimensional pores of the knitted fabric.
Process: RANA adopts an integrated "hot-press melting" process, utilizing the high fluidity of modified PTFE to achieve "full filling" of resin into the knitted fabric (filling rate ≥95%), with lining Sheet porosity ≤0.03% (industry ≥0.2%).

Core: The combination of three-dimensional reticular structure of glass knitted fabric and high filling property of modified PTFE forms a "gap-free" composite layer, making the impermeability (permeability ≤0.0003g/m²·day) and tear strength (≥90N/mm) of the lining Sheet leading the industry.
Advantages: Verified by a Japanese expert team, it shows no penetration after 3 years of immersion in liquid bromine (highly permeable medium) (ordinary lining Sheets leak after 1 year), with a temperature resistance range of -200°C to 280°C and internationally leading process level. As a member of the China Semiconductor Industry Association, the product adapts to the high-purity storage needs of electronic-grade liquid bromine (e.g., semiconductor wafer cleaning).

Application Scenarios: Used in storage tanks and transportation tankers for highly permeable media (e.g., liquid bromine, chlorosulfonic acid). It has provided solutions for SMIC and Qiaoli Chemical (Taiwan, China), ensuring medium purity (metal ion content ≤0.05ppb) and helping customers improve the quality of high-end materials.
