This is a semi-independent, semi-continuous type of standard seal material made from foamed EPDM rubber. It is a clean foam that does not contain sulfur compounds, which are commonly used in rubber crosslinking and raise concerns about metal corrosion. In recent years, it can be used in high-sealing electronic devices that are becoming smaller, without corroding metals, for cushioning, soundproofing, and dust-proofing applications. <Features> - The main component is EPDM rubber, which has excellent properties among general-purpose rubbers, including heat resistance and chemical resistance (acid and alkali). - Our advanced foaming technology provides a low-density and flexible foam. - The cell structure is available in two types: independent bubble type and semi-independent semi-continuous bubble type, meeting user needs through various foaming technologies. - There is also a sulfur-free type, the EH-2200 series. *For more details, please refer to the PDF document or feel free to contact us.

This is a semi-independent, semi-continuous type of standard seal material made from foamed EPDM rubber. It is a clean foam that is commonly used in rubber crosslinking and does not contain sulfur, which raises concerns about metal corrosion. In recent years, it can be used around compact, airtight electronic devices without corroding metal, for cushioning, soundproofing, and dustproofing applications. 【Features】 - Excellent resistance to metal corrosion due to sulfur-free formulation. - Easy to compress due to low stress during compression, and it conforms well to the irregularities of the substrate. This effect provides excellent airtightness and soundproofing. - Superior durability, weather resistance, heat resistance, and chemical resistance. - The foam layer has received UL-94HBF flame retardant certification. *For more details, please refer to the PDF document or feel free to contact us.

It is a foam sealing material that fills the gaps between various types of equipment. It is a foamed mixture of synthetic rubber EPDM in a semi-independent, semi-continuous state. It is designed for higher foaming, and can be used differently for waterproofing, windproofing, dustproofing, soundproofing, and as insulation material depending on the compression ratio of the foam. 【Features】 - Excellent durability, weather resistance, and cold/heat resistance tests (from -20°C to 100°C). It also has superior chemical resistance (to acids and alkalis). - The compression load (stress) is small, so it does not deform the structure after filling the joints. - Being a flexible material, it is easy to compress and use. - With a specific gravity of 0.11, it is lightweight, and since the foam does not fuse together, it is easy to handle and store. *For more details, please refer to the PDF document or feel free to contact us.

This is a high-performance foam created by foaming an EPDM blend, which excels in durability and weather resistance, in a semi-independent, semi-continuous state among general-purpose rubbers. Due to its flexible material, it is easy to compress and provides excellent water and air tightness. As part of the No. 685 series, various tape materials coated with rubber-based and acrylic-based adhesives are available, allowing for selection according to purpose. 【Features】 ■ Excellent durability, weather resistance, cold and heat resistance tests (−20℃ to 100℃), and chemical resistance (acids and alkalis). ■ Low compressive load (stress), preventing deformation of structures after joint filling. ■ Easy to use by compressing due to its flexible material. ■ Lightweight with a specific gravity of 0.13, and the foams do not fuse together. *For more details, please refer to the PDF document or feel free to contact us.

This is a high-performance foam made from an EPDM blend that excels in durability and weather resistance among general-purpose rubbers. As part of the No. 6800 series, various tape materials coated with butyl-based and synthetic resin-based adhesives are available, allowing for selection according to purpose. <Features> - Excellent weather resistance and water tightness, with superior heat resistance compared to foam water-stopping materials like urethane and polyethylene. - EM-142 uses a butyl-based adhesive, providing excellent adhesion to rough surfaces. - No. 681 uses a synthetic resin-based adhesive, excelling in retention, heat resistance, and weather resistance. - Being an independent foam, it offers excellent flexibility and elasticity. - It can be easily applied to complex-shaped gaps. *For more details, please refer to the PDF document or feel free to contact us.

It is a flexible foam made by foaming a mixture of EPDM rubber and a flame retardant, classified as a semi-independent, semi-continuous bubble type, and has received UL-94 and HF-1 flame retardant certification. Various types with an adhesive layer are available, and all can be used differently as waterproof, airtight, soundproof, and thermal insulation materials based on the compression ratio, taking advantage of their flexible foam characteristics. 【Features】 - It contains non-chlorinated flame retardants and has received the most stringent flame retardant certifications, UL-94 and HF-1. - It has low stress during compression, can be easily compressed, and conforms well to the unevenness of the substrate. This effect provides excellent airtightness and soundproofing. - It has excellent heat resistance, weather resistance, and ozone resistance, making it durable for long-term use. *For more details, please refer to the PDF document or feel free to contact us.
