* Values obtained on conditioned test specimens.
Properties measured on natural grades under Dry-as-moulded test specimens and standard testing conditions.
Pigmented grades would record slightly lower mechanical properties as permitted by ASTM D-4066. |

| Injection pressure : The above given values or as sufficient to fill cavities. |
| Conditioning : It is advised to condition components in hot water at 80-100 Deg. C for 2 – 4 hrs. depending upon the component thickness and as required by the subsequent process also to release internal stresses if any to avoid breakage during further assemply. |
| Above parameters are only guidelines and exact process conditions have to be established for each machine/mould depending upon equipment capacity, part geometry. It is given in good faith and no warrant is attached. |
