Standard Series

With variety of density lineup, this series corresponds various application, such as seals, vibration and shock absorption.

  • LE

    LE is the softest type in the Standard series. With its low stress property and compressibility, this type has been widely used for toner seals.

  • L

    L is softer product type in the Standard series. It is used in a wide range of cushioning and packing materials.

  • H

    H is a hard product type in the Standard series. It offers a high physical strength and is used for sealing materials and vibration damping materials.

  • HH

    The HH grade is a hardest product type in the Standard series and used for the foot pads of audio devices, home electric appliances and IT equipment. The C type that has excellent gripping property is also available.(HH-48C)
