Material Profile
PPA (polyphthalamide) is a semi-aromatic polyamide – the aromatic ring structures in the polymer chain give it exceptional heat resistance and creep resistance, far exceeding aliphatic polyamides (PA6, PA12). Glass-fiber reinforcement further increases stiffness and strength.
PPA-GF vs. PPA-CF
| Property | PPA-GF | PPA-CF |
|---|---|---|
| Stiffness | High | Very high |
| Electrical conductivity | No | Slight (CF fiber) |
| Creep resistance | Very good | Very good |
| Material cost | More economical | Higher |
| Surface | Rough, light | Rough, dark |
PPA-GF is the choice when electrical insulation matters or when a more economical alternative to PPA-CF is needed at comparable thermal performance.
Material Sourcing
PPA-GF is a specialty material with limited stock availability. When you place an order, we clarify material batch, lead time and technical datasheets on a project-specific basis.
