"Long-lasting sealing performance" is a core demand across multiple industries — seals that deform easily under prolonged pressure, leading to reduced sealing effectiveness, often result in equipment leakage, increased energy consumption, and even malfunctions. A specialized liquid silicone rubber for sealing, featuring low compression set characteristics, has become the preferred material for long-term stable sealing applications due to its ability to quickly rebound after compression, resist permanent deformation, and offer excellent mechanical properties. It meets the stringent requirements of various industries.

The standout feature of this liquid silicone rubber is its "low compression set" property. Simply put, after being compressed for extended periods, the seal quickly returns to its original shape once the pressure is released, without leaving any permanent deformation marks — much like an elastomer with a "memory function." This ensures that the seal maintains a tight fit over the long term, preventing leaks caused by deformation, significantly extending the seal's service life, and reducing replacement frequency and maintenance costs.

The product adopts a two-component 1:1 weight ratio mixing design, making it convenient and efficient to use. During production, no complex measuring tools are needed. Simply mix equal weights of Components A and B thoroughly, and the material is ready for injection molding or casting processes. Both new and experienced operators can handle it quickly, lowering the production barrier. The mixed material exhibits excellent flowability, easily filling complex mold cavities. Whether for simple flat seals or irregularly shaped silicone components, it ensures precise molding and dimensional accuracy.

In terms of performance adaptability, the product offers seven hardness options ranging from 10 to 70 Shore A, covering needs from soft to rigid across all scenarios. The soft 10 Shore A variant offers an elongation of up to 800%, stretching to eight times its original length, making it ideal for sealing irregular surfaces. The medium 50 Shore A variant provides optimal overall performance, with a tensile strength of 10 MPa and a tear strength of 40 kN/m, offering wear and aging resistance — an ideal choice for universal seals. The rigid 70 Shore A variant delivers strong support, suitable for high-pressure industrial equipment seals.

Additionally, the product features rapid thermal curing and excellent mold release properties. Once molded, it detaches quickly from the mold without sticking, leaving a smooth surface. This shortens production cycles and reduces defect rates. It also offers flexible storage conditions, with an unopened shelf life of up to 12 months below 23°C, allowing manufacturers to stock it as needed.

Currently, this product is widely used in the production of silicone tubes, seals, and miscellaneous silicone components. In the automotive industry, engine seals and door/window gaskets maintain long-term sealing effectiveness thanks to their low deformation properties. In industrial equipment, high-pressure seals rely on high rebound and mechanical strength to resist pressure-induced deformation. In electronics, waterproof seals leverage their soft adaptability to fit precision structures. With its low compression set properties, this product has become a reliable solution for long-term, stable sealing across various industries.
