Notes for the following test:

• Products can always perform and be used at lower temperatures than the indicated range.

• For comparison purposes, Air Oven Aging (AOA) shown for all resins only in the range

from 180C-230C

• Zytel® 70G35HSRX shows slightly higher better performance in AOA and fatigue vs

Zytel® 70G35HSLX. For clarity, only Zytel® 70G35HSLX is shown on the performance

comparison

Notes:Zytel® XT70G35HSL performs in molding as easy as standard glass reinforced Zytel® resins.

Long residence time combined with shorter drying time can lead to some melt viscosity drop.

DPD = Dynamic Pressure Drop offers a direct correlation with dynamic melt viscosity, that correlates with mechanical performance.

To avoid viscosity drop it is not recommended to work beyond 300C and 15 mins HUT
