Kaxite's non‑asbestos jointing sheets are engineered as a safe, reliable, and high‑performing alternative to traditional asbestos gaskets. Manufactured from specially formulated non‑asbestos heat‑resisting fibres, heat‑resisting packing compounds, and high‑grade natural rubber, these sheets are compression‑moulded to deliver exceptional sealing integrity in water, steam, air, and light oil services. As a leading Non‑Asbestos Jointing Sheets manufacturer in China, we offer seven distinct grades – KNXB200, KNXB300, KNXB350, KNNY150, KNNY250, KNNY300, and KNNY350 – each tailored to meet specific temperature, pressure, and oil‑resistance requirements. With a maximum working temperature of 200°C and pressure up to 1.5 MPa, these sheets provide a durable, eco‑friendly solution for flange joints, pipeline connections, and equipment sealing in chemical, petrochemical, power generation, and general engineering sectors. Standard sheet sizes 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 gaskets are available for bulk orders. Backed by ISO 9001:2015 certified quality and full traceability, Kaxite ensures consistent performance and peace of mind for procurement professionals seeking a dependable industrial gasket sheets supplier.
