| About |
|---|
| Fortron 6850L6 offers the lowest warpage available. The easy flowing nature allows this product to be injection molded into thin walled applications. The excellent balance of mineral and glass fibers result in a superior heat resistance and dimensional stability. This grade is inherently flame-retardant along with high hardness and rigidity. Especially used for thin walled by unfavorable flow length-wall thickness ratio. This is the most isotropic grade available.&& |
