Product Description:
The Phenolic Epoxy class fiber laminate 3240 is an electical purposed alkali-free reinforced laminate bonded with phenolic epoxy resin, specifically designed for electrical applications. With a Class B thermal stability rating, it offers excellent mechanical and dielectric properties. This material is widely used in electrical and electronic fields for fabricating insulating components and structural parts in equipment. It is also suitable for use in demanding environments, including high humidity and transformer oil.
Advantages:
- Excellent Dielectric Strength: High electric strength perpendicular to laminations ( ≥14.2 kV/mm at 90°C in oil, 1 mm in thickness), ensuring reliable insulation protection and effective resistance to breakdown, even under demanding conditions.
- Stable Dielectric Properties: A low relative permittivity (≤5.5 at 50Hz), which helps minimize dielectric losses in equipment and contributes to enhanced operational efficiency and stability.
- Dense and Robust Structure: High material density (≥1.8 g/cm³) provides superior mechanical durability and strength, making it suitable for demanding applications that require long service life.
- Superior Surface Quality: The smooth and virtually defect-free surface ensures ease of installation, prevents performance issues such as partial discharges caused by surface imperfections, and guarantees consistent product quality.
