In the vast landscape of industrial materials, few components are as versatile and critical as the Rubber sheet. A fundamental product in sealing, gasketing, insulation, and protection applications, the quality and specifications of a rubber sheet directly influence the performance, safety, and longevity of countless systems. For over two decades, Kaxite Seals has been at the forefront of engineering and manufacturing premium rubber sheets, catering to the rigorous demands of industries worldwide. This guide delves deep into the technical specifications, material varieties, and application best practices of our rubber sheets, providing the detailed information engineers, procurement specialists, and maintenance professionals need to make informed decisions.
Not all rubber is created equal. The choice of polymer base dictates the sheet's resistance to environmental factors, chemicals, temperatures, and mechanical stress. Kaxite Seals offers a comprehensive portfolio of rubber sheet materials.
Beyond material type, precise physical and dimensional specifications are crucial for application success. Below are the standard parameters for Kaxite Seals rubber sheets.
| Material Grade | Hardness (Shore A) | Tensile Strength (MPa) | Elongation at Break (%) | Temperature Range (°C) | Specific Gravity |
|---|---|---|---|---|---|
| NBR 70 | 70 ±5 | 14 Min | 300 Min | -30 to +120 | 1.30 |
| EPDM 60 | 60 ±5 | 10 Min | 350 Min | -50 to +150 | 1.25 |
| FKM 75 | 75 ±5 | 16 Min | 200 Min | -20 to +200 | 1.85 |
| Silicone 50 | 50 ±5 | 7 Min | 400 Min | -60 to +230 | 1.15 |
| Neoprene 65 | 65 ±5 | 12 Min | 280 Min | -40 to +100 | 1.40 |
Kaxite Seals rubber sheets are available in rolls, sheets, and custom-cut blanks to suit various production needs.
The application of rubber sheets is virtually limitless. Here are the primary industries served by Kaxite Seals products.
Q: How do I select the right rubber sheet material for my application?
A: Material selection hinges on the operating environment. Identify the key factors: type of fluids (oil, water, chemicals), temperature extremes, exposure to sunlight/ozone, required pressure sealing capability, and needed physical properties (hardness, compression set). Cross-reference these needs with the material property tables. For complex scenarios, consulting with Kaxite Seals technical support is recommended for a tailored solution.
Q: What is the significance of Shore A hardness in a rubber sheet?
A: Shore A hardness measures the material's resistance to indentation, indicating its softness or firmness. A lower number (e.g., 50) signifies a softer, more conformable sheet good for sealing uneven surfaces. A higher number (e.g., 80) indicates a harder, more rigid sheet better for heavy load-bearing or abrasion resistance. Choosing the correct hardness is vital for achieving an effective seal and ensuring product longevity.
Q: Can Kaxite Seals rubber sheets be custom fabricated?
A: Yes, absolutely. Kaxite Seals specializes in value-added fabrication. We offer precision die-cutting, waterjet cutting, laser cutting, and CNC routing to convert standard sheets into custom gaskets, seals, washers, and complex profiles according to supplied drawings or samples. This service ensures perfect fit and reduces on-site waste and assembly time.
Q: What is the shelf life of a rubber sheet, and how should it be stored?
A: Properly stored, most rubber sheets have a shelf life of 5-10 years. Storage guidelines are critical: keep sheets in a cool, dark, and dry environment (ideally below 25°C/77°F), away from direct sunlight, ozone sources (like motors), and chemicals. Store sheets flat or on a core to avoid permanent creasing or deformation. Do not stretch or compress sheets during storage.
Q: How do I join or splice rubber sheets effectively?
A: For creating large or continuous seals, sheets can be joined. The most common and reliable method is using a specialized rubber adhesive or cement designed for the specific polymer (e.g., NBR cement for NBR sheets). Surfaces must be clean, dry, and lightly abraded. Apply cement to both surfaces, allow it to become tacky, then press firmly together under pressure. For critical seals, vulcanized splicing (a heat and pressure process) provides the strongest, most seamless bond and is a service offered by Kaxite Seals.
Q: Are there fire-resistant or FDA-approved rubber sheet options?
A: Yes. Neoprene (CR) and certain compounded EPDM sheets offer inherent flame-retardant properties. For stringent requirements, specially formulated compounds can be provided. For FDA compliance, specific grades of silicone rubber and EPDM are manufactured to meet FDA CFR 21 and USP Class VI standards for indirect food contact, making them suitable for food processing and pharmaceutical applications.
