It is made from olefin resin through special spinning process and electret process. With high filtration efficiency, high permeability and excellent pleating performance, It is suitable for combining with various materials via heat, adhesive, or ultrasonic bonding, providing mechanical strength while enhancing the durability of composite filter materials. It can also be used independently in applications such as automotive filtration, HVAC, composite materials, and other fields with specific filtration requirements.
