Recently, Shenzhen Hongyejie Technology Co., Ltd. (Hongye Silica Gel) officially launched professional silicon gel products HY-9400 and HY-9405 for HEPA tank sealing applications. These two liquid tank filters are sealed with silicone gel using a two-component additive formula, designed specifically for high demand purification environments such as clean rooms, dust-free workshops, and biomedicine. They achieve significant improvements in sealing performance, self-healing ability, and long-term stability.
Deeply cultivating the field of liquid tank sealing and accurately matching industry needs
Liquid tank HEPA high-efficiency air filters are widely used in clean room end air supply systems in industries such as semiconductor manufacturing, pharmaceutical production, food processing, precision instruments, and aerospace. In cleanrooms with ISO 5 and higher cleanliness levels, the sealing reliability between the filter and the frame directly determines whether the entire purification system can operate in compliance with standards. Poor sealing can lead to leakage of unfiltered air bypass, which can affect product yield in mild cases and result in the scrapping and shutdown of the entire batch of products.
Traditional sealing solutions have their own limitations: rubber sealing strips are prone to aging, deformation, and elastic attenuation after repeated insertion and removal, and the sealing gap gradually increases after long-term use; Polyurethane sealant is prone to degradation and failure in high temperature environments; After curing, the epoxy sealing material forms a brittle rigid body. Although the initial sealing effect is good, the filter must be destructively removed during replacement, which not only damages the filter frame but also wastes the sealing material, resulting in high maintenance costs. The industry urgently needs a sealing solution that can ensure long-term sealing reliability and support repeated plugging and replacement of filters.
The R&D team of Hongye Silicone has systematically optimized the formula based on the existing liquid tank jelly gel technology to address the pain points in this industry. They have launched two upgraded models, HY-9400 and HY-9405. After curing, the new product forms an extremely soft gel with hardness lower than Shore A zero, texture similar to jelly, and closely adheres to the aluminum tank wall to form an airtight sealing layer. Its core advantage lies in its unique self-adhesive and self-healing properties - when the filter is taken out of the tank, gel can be easily separated from the filter; After the filter is put in again, the gel automatically recovers the sealing effect without re sizing. This feature not only greatly simplifies the installation and maintenance process of the filter, but also significantly reduces operation and maintenance costs and material waste, making it particularly suitable for purification systems that require regular replacement of filter cartridges.
Customized services and free sample support
Hongye Silicone always adheres to customer demand orientation. The viscosity, operating time, curing speed, color, hardness and other parameters of HY-9400 and HY-9405 can be customized and adjusted according to specific customer application scenarios. The company has a research and development team of over 100 people, which can quickly respond to various customized needs. Before placing bulk orders, customers can apply for free samples for testing and evaluation to ensure that the product performance matches the actual process.
Red Leaf Silicone Liquid Tank Filter Sealing Silicone has been exported to 138 countries and regions worldwide, serving over 20000 customers. The export volume of
liquid silicone has been among the top in China for many consecutive years. The launch of HY-9400/HY-9405 further enriches the company's product line in the field of purification equipment sealing, providing more professional and reliable sealing solutions for high-efficiency air filter manufacturers.
