What are the main functions of cabinet seals?

Cabinet seals are widely used and highly popular in the market, thanks to their versatile and advantageous features. However, there are several key points users should know when employing them—after all, many customers remain unaware of these important details.

Although cabinet seals are widely used, most readers still lack a thorough understanding of this product—especially its key features. Today, we’re taking this opportunity to shed some light on it for you. First off, these cabinet seals are crafted from a unique blend of EPDM rubber foam material, offering exceptional elasticity, resistance to compression deformation, and outstanding durability against aging, ozone exposure, and chemical degradation. They can operate reliably across an extremely wide temperature range—from -40°C to 120°C. What’s more, these seals come equipped with a distinctive metal clip and tongue-and-groove fastening system, ensuring they’re both sturdy and long-lasting. As a result, they play a critical role in various types of electrical cabinets. If you’re considering using them, there are several essential facts you should know. For instance, cabinet seals are typically made from dense rubber, foam rubber, and reinforced with steel wires or steel plates. They boast superior performance characteristics, including excellent UV resistance, chemical solvent tolerance, and unmatched physical and chemical properties compared to similar products on the market. Because of these remarkable attributes, they’ve found extensive applications in areas like automotive body sealing and architectural insulation. Our company specializes in developing and designing seals that deliver exceptional cold- and heat-resistant, foamed, solid, and even custom-designed performance capabilities—all tailored to meet specific application needs. We pride ourselves on being a fully integrated enterprise that combines research, production, and sales under one roof. With robust manufacturing facilities, cutting-edge equipment, and comprehensive quality-control systems, our products have stood the test of time over the past two decades, consistently meeting—and often exceeding—the demands of today’s dynamic market.

Cabinet sealing strips are primarily used in various types of cabinets, electrical enclosures, and other mechanical equipment, serving key functions such as securing components, providing sound insulation, and offering protection against water, dust, and air leakage—essentially ensuring dust- and rain-proof performance. These sealing strips are crafted from dense EPDM rubber, renowned for their exceptional elasticity, compressive strength, resistance to aging, ozone exposure, and chemical corrosion. They can operate effectively across a wide temperature range (-40°C to 120°C), while their unique metal clamps and tongue-and-groove fasteners ensure long-lasting durability. As a result, they play a critical role in enhancing the performance and reliability of electrical cabinets. As a vital working medium within cabinet systems, these sealing strips facilitate energy transmission, conversion, and control. At the same time, they provide essential lubrication, corrosion protection, rust prevention, and cooling effects for individual components in hydraulic systems. Currently, both domestically and internationally, EPDM rubber remains the most commonly used material for sealing applications. In certain specialized environments, however, plastics or various metals may also be employed. Regardless of the material chosen, it must possess robust mechanical and physical properties—such as tensile strength, set resistance, and elongation—attractively balanced with moderate hardness to minimize compression set and deformation. Additionally, the material should exhibit excellent compatibility with working fluids, resisting swelling, degradation, and hardening under operational conditions.
