EPDM coated fiberglass fabric | Fabric expansion joint material

I. Core Product Structure

1. Base Material Layer: High-purity alkali-free glass fiber yarn is selected and woven into fiberglass cloth through precision weaving. It has uniform weaving density and neat yarn arrangement, with core characteristics such as high strength, high modulus, high temperature resistance, non-combustibility and good dimensional stability. It can effectively support the coating, prevent the product from stretching, deforming and damaging during use, and play a basic role in heat insulation and insulation.
2. Coating Layer: High-quality EPDM rubber is uniformly coated on the surface of the fiberglass base material through professional coating technology. The coating thickness is controllable (conventional 0.1-0.5mm), with a smooth surface, no bubbles, pinholes or missing coating. EPDM rubber itself has excellent weather resistance, ozone resistance and chemical corrosion resistance, which can effectively isolate water vapor, oil stains and acid-base media in the external environment, and at the same time improve the flexibility and sealing performance of the product, extending the service life of the product.

II. Detailed Properties & Features

1. High Temperature Resistance: The long-term service temperature can reach -40℃~160℃, and the short-term tolerance temperature can reach 200℃. It will not soften, deform or burn in high-temperature environments, and can be stably applied to medium and high-temperature industrial scenarios, which is superior to ordinary rubber-coated fabrics.
2. Weather Resistance & Anti-aging Performance: It has excellent ozone resistance, UV resistance and weather resistance. When exposed to harsh outdoor environments such as sunlight, wind and rain, severe cold and extreme heat for a long time, it will not crack, age, discolor or embrittle. The service life can reach 5-10 years, far exceeding that of ordinary coated fabrics.
3. Medium Resistance: It has good tolerance to various oily media such as mineral oil, lubricating oil and fuel oil, and can resist the erosion of weak acids, weak alkalis, salt spray and other chemical media without swelling or peeling. It is suitable for industrial environments with more oil pollution and chemical corrosion.
4. Mechanical Performance: Relying on the high strength advantage of the fiberglass base material, the product has high tensile strength and good tear strength, which is not easy to be damaged or stretched and deformed. At the same time, it has good flexibility and can be cut, folded and bent according to actual needs, which is convenient for processing and installation without brittle fracture.
5. Safety & Environmental Protection Performance: The product itself does not contain toxic and harmful substances, and it is low-smoke and low-toxic when burned, without releasing harmful gases, which meets environmental protection standards. At the same time, it has good flame retardant performance, reaching the flame retardant grade B1, which can effectively delay the spread of fire and improve the safety of use.
6. Sealing & Waterproof Performance: The EPDM coating has excellent sealing and waterproof performance, which can effectively isolate water vapor and dust, prevent medium leakage, and is suitable for scenarios requiring sealing and waterproofing. At the same time, it has a certain air permeability to avoid internal moisture accumulation.
7. Electrical Insulation Performance: The fiberglass base material itself has good electrical insulation performance. With the EPDM coating, the insulation performance is further improved, which can be used for the insulation protection of electrical equipment to prevent leakage, short circuit and other problems.

III. Core Product Advantages

1. Complementary Performance & Wide Application Range: It perfectly combines the high strength and high temperature resistance of fiberglass with the weather resistance, oil resistance and flexibility of EPDM rubber, solving the pain points of pure fiberglass cloth being brittle and easy to damage, and ordinary rubber cloth having low strength and poor high temperature resistance. It can adapt to various complex environments.
2. Strong Durability & High Cost-Effectiveness: The coating is closely combined with the base material, not easy to fall off or age, with a long service life, no need for frequent replacement, which greatly reduces the use cost. At the same time, the production process is mature, and the product price is reasonable. Compared with high-end coated products such as PTFE and silicone, it has higher cost-effectiveness.
3. Convenient Processing & Strong Adaptability: It can be cut, spliced, heat-sealed, bonded and other processed according to customer needs to make products of different sizes and shapes (such as coiled materials, sheets, sealing sleeves, protective covers, etc.), which are suitable for the installation and use of various equipment and scenarios, without complex processing equipment.
4. Environmental Protection & Safety, Meeting Standards: It has no toxic and harmful substances, low smoke and low toxicity when burned, and the flame retardant performance meets the standards. It conforms to domestic and foreign industrial environmental protection and safety standards, and can be safely applied to food processing, medicine, civil and other scenarios with high environmental protection requirements.

IV. Main Application Fields

1. Industrial Pipeline & Equipment Field: It is used to make flexible connectors, expansion joints and ventilation pipes for industrial pipelines, especially suitable for medium and high-temperature pipelines, chemical pipelines and oil pipelines, which can play the roles of heat insulation, sealing and corrosion protection, and compensate for the displacement and vibration of pipelines during operation.
2. Thermal Insulation & Protection Field: It is made into thermal insulation blankets, protective covers and heat shields, which are used for thermal insulation and protection of industrial equipment, such as boilers, furnaces, valves, flanges, engines and other equipment, to reduce heat loss and protect the safety of equipment and operators.
3. HVAC & Construction Field: It is used in HVAC systems, air conditioning ducts and building waterproofing and sealing projects, which can play the roles of heat insulation, waterproofing and noise reduction, and improve the energy efficiency and comfort of buildings.
4. Electrical Equipment Field: It is used as insulation cloth, insulation sleeves and cable protective covers for electrical equipment, such as motors, transformers, cables, etc., to prevent electrical leakage and short circuit, and ensure the safe operation of electrical equipment.
5. Marine & Automobile Field: It is used for the insulation, sealing and corrosion protection of marine equipment and automobile parts, such as ship pipelines, engine covers, automobile exhaust systems, etc., which can adapt to the harsh marine and automotive environments and extend the service life of parts.
6. Other Fields: It is also used in fire-fighting equipment (such as fire curtains, fire blankets), food processing workshops, medical equipment insulation and other scenarios, providing safe and reliable protection for various fields.
