Nitto Denko Foam EPDM Rubber Seal Material "Eptsealer"
Fills all gaps, shutting out heat, water, sound, and vibrations! It is a high-performance sealing material made of durable EPDM rubber foam.
【Features】 It excels in heat resistance and chemical resistance, demonstrating stable performance over a long period. There is a rich lineup that can be differentiated according to applications, including flame-retardant types, soft types, and high-foaming types. It is used in various fields such as automobiles, housing, and home appliances. - Composed mainly of EPDM rubber, it possesses excellent properties among general-purpose rubbers, including heat resistance and chemical resistance (acid and alkali). - Our superior foaming technology provides low-density and flexible foam materials. - The cell structure comes in two types: independent bubble type and semi-independent semi-continuous bubble type, responding to user needs through various foaming technologies. - Our processing technology allows for customization into the desired shape. (Raw material size: 1000mm x 2M) 【Sales Information】 - Please specify the "product number," "thickness," "width," and "length." *For special shapes, drawings can be confirmed. - We will process from the standard raw material size of "1,000mm x 2M" to your specified size. *Some product numbers are available in longer sizes. ■ Delivery time (estimate): For sizes (thickness) with raw material stock, approximately 1 to 2 weeks. For custom sizes, about 1.5 months. ■ Production lot: If raw material stock is available, one sheet of raw material. For custom sizes, from one case (quantity varies by thickness).
basic information
**No. 6800 Series** - Due to its independent foam structure, it excels in flexibility and elasticity. (50% compression hardness 8.0N/cm²) - EM-142 uses a butyl-based adhesive, which excels in adhesion to rough surfaces. - No. 681 uses a synthetic resin-based adhesive, which excels in retention, heat resistance, and weather resistance. **No. 685 Series** - The semi-independent, semi-continuous bubble structure makes it a flexible material that is easy to compress, with excellent waterproof and airtight properties. (50% compression hardness 0.6N/cm²) - Various tape materials coated with rubber-based and acrylic-based adhesives are available and can be selected according to the purpose. **EE-1000 Series** - This is a semi-independent, semi-continuous bubble type with higher foaming, serving as waterproof, windproof, dustproof, soundproof, and insulation material depending on the compression ratio of the foam. (50% compression hardness 0.45N/cm²) - The compression load (stress) is low, preventing deformation of the structure after filling joints. **EC-100 Series** - A semi-independent, semi-continuous bubble type made by foaming a mixture of EPDM rubber and flame retardants. (50% compression hardness 0.28N/cm²) - Certified for flame retardancy under UL-94, HF-1. - Excellent heat resistance, weather resistance, and ozone resistance, suitable for long-term use.
