Thin-Film OPP Film for Film Capacitors

*Photos are for illustrative purposes only.

This is dielectric film for use in film capacitors, widely used in applications such as electric vehicles and electronic devices. A simultaneous biaxial drawing system and stringent thickness control enables stable production of thin-film products. Iwatani offers ultrathin products down to a thickness of 2 µm using world-leading manufacturing technology, enabling capacitors to be reduced in size with increased dielectric properties.

Product Standards	Thickness	1.9 µm to 14.8 µm
Product Standards	Main widths	620 mm, 820 mm, 920 mm

Paper Separators for Aluminum Electrolytic Capacitors

These products are separators for compact aluminum electrolytic capacitors with high electrostatic capacity. They’re capable of meeting a broad range of stringent quality requirements, including durability against voltage, storable electrostatic capacity, permeability, and thickness controls.

Aramid Paper (Insulation)

Meta-aramid paper offers excellent surface smoothness and flexibility attributable to calendar processing. It’s widely used as heat-resistant insulation (H type) due to its low halogen characteristics and high heat resistance (UL temperature rating 210°C). Iwatani offers aramid paper manufactured in China.

Product Characteristics	Applications	Transformer/motor insulation
	Features	Mechanical strength, heat resistance, chemical resistance, etc.
	Thickness	0.04 mm to 0.76 mm
