High-Strength Rubber and Silicone Sealing Kit
Universal Application for Vehicles, Compressors, Industrial Equipment & Home Appliances
Product Overview
This non-asbestos rubber and silicone sealing kit offers a durable, oil-resistant, and eco-friendly solution for a wide range of sealing needs. Available in thicknesses from 0.5mm to 5.0mm, it’s designed for users who need both flexibility and long-term reliability in demanding conditions.
By selecting the thinnest sheet that meets your requirements, you can reduce material waste, enhance heat transfer efficiency, and minimize installation costs—all while maintaining an excellent seal.
General Features of Non-Asbestos Sealing Sheet
Engineered from aramid fibers, non-asbestos minerals, synthetic fibers, and NBR/silicone binders, these sheets combine resilience and safety. The hot-compression and controlled vulcanization process ensures stable density, uniform strength, and superior oil resistance.
They perform exceptionally well in automotive systems, diesel engines, compressors, pipe joints, pumps, and marine machinery, where reliable sealing is crucial to prevent leakage under varying pressures and temperatures.
