Product Introduction

Raw Materials: Imported PVDF resin, with glass knitted fabric as the backing. PVDF's high fluidity makes it easier to penetrate into the three-dimensional pores of the knitted fabric.
Process: Through "hot-press melting" process, utilizes PVDF's low viscosity characteristic to achieve "full filling" of resin into the knitted fabric, with lining Sheet porosity ≤0.03% (industry ≥0.1%).

Core: The combination of three-dimensional reticular structure of glass knitted fabric and high filling property of PVDF forms a "gap-free" composite layer, making the impermeability (permeability ≤0.0004g/m²·day) and tear strength (≥70N/mm) of the lining Sheet leading the industry, suitable for highly permeable media.

Advantages: Tested by East China University of Science and Technology for permeability, it shows no penetration after 3 years of immersion in liquid bromine (highly permeable medium) (ordinary PVDF Sheets leak after 1 year), with a temperature resistance range of -40°C to 150°C. RANA holds the invention patent for Manufacturing Process of Large Chemical Equipment and Its Lining Anticorrosive Sheets, with internationally leading process level.

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 ≤0.1ppb) and helping customers improve the quality of high-end materials.
