With any material change there is much to consider besides just the cost.<\/p>\n

Operating Environment: <\/strong>
\nWhat is the average operating temperature?
\nMaterial RTI value is critical for this
\nWhat is the peak operating temperature?
\nHDT is probably the most critical value
\nIs it wet or extremely dry?
\nWater Absorption rates can have an impact on mechanicals. Nylons have some of the highest rates.
\nIs it exposed to chemicals?
\nChemical compatibility specifications must be considered<\/p>\n

Mechanical: <\/strong>
\nIs it under any kind of constant external stress
\nCreep values must be considered
\nDoes it have to sustain and kind of impact
\nImpact strength is a critical value
\nFilled materials generally have lower impact values than non-filled materials
\nManufacturing process
\nSome processes naturally lend themselves to more mechanically robust plastic parts. Mostly due lower internal stress levels within the component itself. An example would be compression molding versus injection molding<\/a>.<\/p>\n

Other: <\/strong>
\nFlammability Requirements?
\n5VA, 5VB, V0, V1, V2 or HB?
\nDielectric Strength
\nI believe you are probably aware of this requirement as it is an electrical connector you are speaking about<\/p>\n

Environmental: <\/strong>
\nIs your company under any kind of environmental restrictions with regards to the products you sell like RoHS, Blue Angle or any of the EU Environmental requirements?
\nThe flame packages in these materials may or may not be compliant with these and other environmental restrictions (Like Halogenated\/Brominated flames packages).
\nThe environmental agencies vary in their restrictions and a thorough evaluation of each is required in order to insure you do not conflict with them in your material selection.<\/p>\n

This may seem like a lot to consider, and it is, but as an old mentor of mine use to tell me “It is better to make sure you cover all your bases than to be celebrating at home plate only to realize you just made an out.”<\/p>\n","protected":false},"excerpt":{"rendered":"
