Non-metallic skin fabric is an essential component of non-metallic compensators. Due to different flowing mediums, the materials of non-metallic skin fabric vary significantly. Below is a general introduction by Universal Bellows about various types of non-metallic skin fabric:

1. Silicone Fabric: It’s produced by coating or calendering glass fiber cloth and organic silicone rubber. Composed of high-temperature resistant, corrosion-resistant, and high-strength glass fiber cloth, impregnated or rolled with organosilicon rubber, it’s a high-performance, versatile composite material.
2. Glass Fiber Fabric: An engineering material with excellent properties such as non-flammability, corrosion resistance, high temperature resistance, low temperature absorption, and low deformation coefficient. This new material covers various fields such as electrical appliances, electronics, transportation, chemical engineering, construction engineering, thermal insulation, sound absorption, firefighting, and environmental protection.
3. Fluororubber Fabric: A modern high-temperature and corrosion-resistant fluoroelastomer, composed of glass fiber coating. It’s a new type of versatile composite material. Its unique high-temperature resistance up to 300 degrees allows it to withstand various lubricants, fuels, and compression oils under high-temperature conditions.
4. Polytetrafluoroethylene (PTFE) Fabric: This product is made by impregnating glass fiber fabric with polytetrafluoroethylene emulsion, then processed through drying and sintering. It exhibits high-temperature resistance and high strength similar to glass fiber fabric, along with outstanding insulation and anti-stick properties of polytetrafluoroethylene.
5. Ceramic Fiber Fabric: A novel high-temperature insulation material. It’s characterized by its resistance to high temperatures of 1200 – 1350 degrees, acid and alkali resistance, lightweight, resistance to thermal shock, low thermal conductivity, and excellent insulation properties. It is widely used in industrial furnace insulation, high-temperature pipe wrapping, fireproof doors in high-rise buildings, cable insulation, protective clothing, gloves, and high-temperature non-metallic compensators.
6. Steel Wire Silicone Fabric: A new type of polymer elastic material exhibiting excellent heat aging resistance, high insulation performance, and outstanding weather aging resistance. Composed of glass fiber coated with steel wire silicone, it’s a high-performance, versatile new material extensively used in aerospace, chemical, large power generation equipment, machinery, metallurgy, non-metallic compensators, and other fields.

Non-metallic silicone skin

Integral fluororubber skin
The integral vulcanized fluororubber skin is the latest developed technological innovation. Traditional expansion joint skins are known to have multiple layers and are sewn using a sewing machine, with the primary drawback being the complex crafting process. Installation is cumbersome, belonging to the customized product category, with fixed width, and once processed, cannot be later trimmed (also leading to longer supply cycles). In response to customer needs, we have developed the latest integrated composite skin, composed of 5-7 layers of fireproof fabric and fireproof rubber compound. It boasts high adhesive strength, doesn’t peel off in the middle, is easily trimmed, offers flexible width adjustment, and can be cut on-site during construction, reducing losses caused by initial measurement errors. It has a shorter supply cycle, usually available in stock, offers good strength, and ensures stronger sealing.
