EPDM strip with steel band composite sealing strip

Product Description

Product Introduction
EPDM strip with steel band composite sealing strip It is a high-performance sealing product that employs an advanced composite manufacturing process to seamlessly integrate premium EPDM rubber with a high-strength steel hoop, fully leveraging the superior properties of both materials.
Key Features
- Excellent weather resistance : EPDM rubber exhibits excellent resistance to ultraviolet radiation, ozone, and climatic aging, maintaining superior physical properties even under harsh environmental conditions.
- Outstanding elastic recovery : It can quickly regain its original shape after compression, ensuring long-term, stable sealing performance.
- High-strength support : Built-in steel hoops provide additional structural support, enhancing the product’s compressive strength and service life.
- Excellent chemical resistance : Exhibits excellent resistance to a wide range of chemicals
Technical Specifications
This sealing strip can be custom‑made to various dimensions according to customer requirements, with a standard hardness range of 60–80 Shore A, an operating temperature range of –40°C to +120°C, a tensile strength of ≥8 MPa, and an elongation at break of ≥300%.
Application areas
1. Architectural doors and windows : Used for sealing aluminum alloy doors and windows, as well as PVC‑steel doors and windows, effectively preventing rainwater infiltration and air leakage.
2. Automotive industry : Suitable for sealing doors, windows, engine hoods, and other components.
3. Industrial equipment : Used for sealing and protecting various types of mechanical equipment
4. Home appliances : Sealing components for household appliances such as refrigerators and washing machines
Installation Advantages
The product features a well‑thought‑out design and easy installation, requiring no special tools; it can be directly fitted into the pre‑installed groove. Its steel‑band construction ensures that the sealing strip remains stable and does not deform or detach over long‑term use, resulting in low maintenance costs and excellent value for money.
