Point of the Proposed Technology

Effect(s)

New Technology

Raw materials in use: Carbon fibers, glass fibers, aramid fibers, and other high-strength fibers.
Tape width: The tape width can be set to any value.
Minimum width:　　　 2.0 mm; maximum width: 1,000 mm @ medium temperature type
Minimum width:　　　 2.0 mm; maximum width: 300 to 500 mm @ high temperature type (from December 2019)
Tape length:　　　 Maximum 2,000 M (currently) Further i ncrease of length under consideration
Thickness:　　　 Minimum: 0.04 mm; maximum: 0.35 mm (performance-based); Thickness level can be adjusted.
Surface smoothness: High surface smoothness has made it possible to adapt to high-speed processes such as ATL/TLP.
Mechanical properties: There is high performance to realize the strength of theoretical values according to the compounding rule.
Tailored capability: It is possible to respond to individual setting in line with customer specifications
