Description
Kaxite's acid‑resistant asbestos rubber sheets are specially formulated to withstand aggressive chemical attack in demanding industrial applications. Manufactured from high‑quality asbestos fibre blended with acid‑resistant synthetic rubber and heat‑cured under compression, these sheets deliver outstanding resistance to sulfuric, hydrochloric, and nitric acids, as well as other corrosive media. As a leading Corrosion‑Resistant Rubber Supplier in China, we offer these sheets with a working pressure of 2.5 MPa and a refractoriness of 200°C, making them ideal for sealing flange joints, equipment covers, and pipeline connections in chemical plants, laboratories, and metal finishing facilities. Standard dimensions include 4100×1500mm, 2000×1500mm, 1500×1360mm, 3810×1270mm, 1270×1270mm, and 1500×1500mm, with thicknesses from 0.5 mm to 6.0 mm. Custom sizes and die‑cut shapes are available for bulk orders. With ISO 9001 certified quality and full traceability, Kaxite ensures consistent performance and long service life. Whether you need a reliable Custom Rubber Sheet Factory solution or off‑the‑shelf gasket material, our acid‑resistant sheets provide the chemical durability your equipment requires.
Acid immersion test: 48h in 18mol/L H₂SO₄, 12mol/L HCl, or 18mol/L HNO₃ – no surface bubbles or leakage.

All acid immersion tests performed at room temperature (21–25°C) per JC/T555-2010. Custom formulations available for specific acid concentrations.
Our acid‑resistant asbestos rubber sheets are produced using select long‑fibre asbestos, blended with specially compounded acid‑proof synthetic rubber and heat‑resisting additives. The mixture is calendered and compression‑moulded under controlled temperature and pressure to achieve uniform density and consistent thickness. Each batch undergoes rigorous quality checks – including tensile strength, compressibility, and acid immersion testing – to ensure compliance with JC/T555-2010. The result is a durable, non‑porous sheet that maintains its sealing integrity even when exposed to concentrated acids at elevated temperatures. As a Custom Rubber Sheet Factory, we also offer custom thicknesses, sizes, and die‑cut shapes to match your specific flange or equipment requirements.
