Your Challenges, Our Solutions: The Power of Kuraray GENESTAR™ PA9T


Overheating & Fast Charging Stress

The challenge:

Higher energy density and fast charging create extreme thermal loads. Standard polymers lose mechanical stability at hot spots.

GENESTAR™ PA9T solves this by:

  1. High temperature performance
  2. Stable mechanical properties over a wide temperature range
  3. Proven suitability for thermal management components
     

TO TOP

Aggressive Coolants & Hydrolysis

The challenge:

New battery cooling concepts use increasingly aggressive fluids, leading to chemical attack, swelling and premature failure.

GENESTAR™ PA9T solves this by:

  1. High chemical resistance to different cooling media
  2. Excellent hydrolysis resistance (even at high temperature)
  3. Material stability over long service life
     

TO TOP

High voltage safety at 800–1000 V

The challenge:

Next generation battery systems push voltage levels beyond conventional limits, increasing the risk of tracking and failure.

GENESTAR™ PA9T solves this by:

  1. Outstanding electrical insulation properties
  2. Extremely high tracking resistance (CTI performance beyond traditional limits)
  3. Enables compact, lightweight high voltage components
     

TO TOP

Moisture uptake & dimensional stability

The challenge:

Moisture absorption leads to dimensional changes, tolerance issues and NVH problems over lifetime.

GENESTAR™ PA9T solves this by:

  1. Very low water absorption (lowest among high heat polyamides)
  2. Excellent dimensional stability
  3. Reliable performance in hot/wet environments
     

TO TOP

Contamination & leach out risks

The challenge:

Ion or oligomer leach out can contaminate cooling systems and affect electrical performance.

GENESTAR™ PA9T solves this by:

  1. Low ion and oligomer leach out
  2. Increased system cleanliness and reliability
     

TO TOP

Complex parts & industrialization pressure

The challenge:

Battery designs demand thin walls, complex geometries and robust joining methods – at scale.

GENESTAR™ PA9T solves this by:

  1. Excellent processability for injection molding and extrusion
  2. Good laser weldability
  3. Supports complex, highly integrated component designs
