In the vast world of industrial materials, few are as versatile and indispensable as the Rubber sheet. At Kaxite, we have dedicated decades to mastering the formulation and manufacturing of high-performance rubber sheeting, providing durable, reliable solutions for countless applications across global industries. A rubber sheet is more than just a piece of elastomer; it is a critical component engineered to provide sealing, insulation, protection, and vibration damping. The key to its effectiveness lies in selecting the right compound, thickness, and hardness for the specific environmental and mechanical demands it will face. From automotive gaskets and industrial lining to food-grade conveyors and architectural seals, the correct rubber sheet ensures longevity, safety, and operational efficiency.
Selecting the optimal rubber sheet requires a detailed understanding of its physical and chemical properties. These parameters dictate how the material will perform under stress, temperature, and exposure to various elements. Below is a breakdown of the most critical specifications.
At Kaxite, we manufacture a comprehensive range of rubber sheets to meet diverse industrial needs. The following table provides a clear comparison of our standard product lines.
| Product Series | Base Compound | Standard Hardness (Shore A) | Standard Thickness Range | Temperature Range (Approx.) | Key Properties & Typical Applications |

| Kaxite-EP Series | EPDM | 50, 60, 70 | 1mm to 20mm | -50°C to +150°C | Superior weather/ozone/steam resistance. Automotive weatherstripping, roof membranes, cooling system gaskets. |
| Kaxite-SL Series | Silicone (VMQ) | 40, 50, 60, 70 | 0.5mm to 10mm | -60°C to +230°C | High & low-temperature flexibility, FDA options available. Food processing, medical devices, thermal insulation. |
| Kaxite-NC Series | Neoprene (CR) | 50, 60, 70 | 1.5mm to 15mm | -40°C to +100°C | Good all-purpose resistance to weather, flames, and moderate chemicals. HVAC gaskets, marine pads, protective liners. |
| Kaxite-FK Series | Fluoroelastomer (FKM) | 70, 75, 80 | 1mm to 6mm | -20°C to +200°C | Exceptional chemical and heat resistance. Seals for aggressive chemicals, aerospace, and oil & gas industries. |
Q: How do I choose the right type of rubber sheet for my application?
A: The selection process hinges on the operating environment. Identify the primary challenges: Are oils, fuels, or solvents present? What is the required temperature range? Is there exposure to sunlight, ozone, or weathering? Is FDA compliance or flame resistance needed? For instance, use Nitrile for oil resistance, EPDM for outdoor weather exposure, and Silicone for extreme temperatures. Cross-reference these needs with the material properties listed in our specification table. Consulting with a Kaxite technical specialist can ensure a perfect match.
Q: What is the significance of hardness (durometer) in a rubber sheet?
A: Hardness, measured in Shore A, directly affects sealing capability, flexibility, and load-bearing capacity. A softer sheet (lower Shore A number) will compress more easily to fill surface imperfections, creating a better seal on uneven flanges. A harder sheet provides more structural support, resists extrusion under high pressure, and offers better abrasion resistance for lining applications. For static seals, a medium hardness (60-70 Shore A) is often a good starting point.
Q: Can Kaxite rubber sheets be custom-cut or fabricated?
A: Absolutely. Kaxite offers comprehensive fabrication services. Our sheets can be precisely die-cut, waterjet-cut, or stamped into custom gaskets, seals, washers, and complex shapes. We can also provide slitting, skiving (tapering edges), and splicing to meet specific dimensional requirements, minimizing on-site waste and installation time for our clients.
Q: What are the differences between closed-cell and open-cell sponge rubber sheets?
A: This is a crucial distinction. Closed-cell sponge rubber contains sealed air pockets, making it impermeable to water, air, and gases. It is excellent for waterproof sealing and floating applications. Open-cell sponge rubber has interconnected pores, allowing air, water, and sound to pass through; it is highly compressible and is primarily used for cushioning, sound dampening, and filtration. Kaxite produces both types in various compounds to suit specific functional needs.
Q: How should I store rubber sheets to maximize their shelf life?
A: Proper storage is essential to prevent premature aging. Store rubber sheets in a cool, dark, and dry environment, away from direct sunlight, ozone generators (like electric motors), and heat sources. Ideal storage temperature is between 10°C and 25°C (50°F and 77°F). Keep the sheets lying flat, not on their edge, to prevent permanent deformation. Avoid contact with sharp objects, heavy metals (like copper and manganese), and solvents. When stored correctly, most Kaxite rubber sheets have a shelf life of several years.
Q: Are there eco-friendly or sustainable rubber sheet options available from Kaxite?
A: Yes, Kaxite is committed to sustainable manufacturing. We offer selected lines containing recycled rubber content where performance criteria allow. Furthermore, our EPDM and Natural Rubber compounds are inherently more sustainable choices. We also develop sheets that meet various industry-specific environmental and regulatory standards.
