Benefits and technical data 

What is TAFNEX™?

TAFNEX™ CF-PP UD is an unidirectional tape (UD tape) consists of carbon fiber and polypropylene (PP) achieved by unique technology of Mitsui Chemicals. Using this material as reinforcement, it can reduce part weight while retaining strength. The polypropylen matrix offers excellent processability, low moisture absorption and short processing time. TAFNEX™ CF-PP can be used for a wide range of applications.

The Benefits

Carbon Fiber’s benefit

+ Low Density Fiber (1.80 g/cm³)
+ High Tensile Strength
+ Resistance to Corrosion
+ Low Thermal Expansion
+ Durability

PP’s benefit

+ Low Density (0.90 g/cm³)
+ Water Resistance
+ Chemical Resistance
+ High Workability
+ Relatively Lower Cost
+ Recyclable

The high mechanical properties of this combination is a result of the highly bonded interface between CF and PP

Mitsui Chemicals developed in cooperation with a fiber manufacturer a special bonding technology, together with a new recipe for PP to make fully impregnated PP-CF UD tape material (TAFNEX™ CF-PP UD).
