Teijin Frontier Introduces THERMOFRONT™: A Sustainable, High-Performance Insulation Brand

Tokyo, October 2, 2025 — Teijin Frontier Co. Ltd. launches THERMOFRONT™. The company presents a master brand for sheet insulation. Teijin Frontier uses its skill in nonwoven fabric making and recycling. It makes this insulation with over 70% ECOPET® recycled polyester fiber. It also adds hollow, cross-sectional fibers. It mixes in functional raw materials to boost heat retention.

Key Features of THERMOFRONT™ Insulation

• Sustainability:
  More than 70% recycled content comes from ECOPET® polyester fiber. This fact improves its green profile.

• Thermal Performance:
  The hollow, cross-sectional staple fibers boost heat retention. They work better than old-style polyester sheets.

• Advanced Fabric Technology:
  The brand uses its own nonwoven fabric designs. It also improves sheet processing. Both steps raise durability and function.
