Outdoor enclosure
Outdoor enclosure
(OP)
I usually work with indoor components so I'm not used with outdoor ones.
We are developing a new product that work near a solar panel.
So the plastic case has to resist to UV and weather, in a temperature range from -25°C to 120°C.
Can you help me?
Thanks

What you are looking is a whetherable material.
If it's an electrical box most probably you will need Flame retardant producct. Is that correct?
I will recommend to take a look in the major Electrical boxes producers.
The material most used is Thermostable (SMC), or PBT with 30%GF.
I will not go for PA GF due the lack of flexibility at low temp ar PC due the lack of UV resistence.
Other solution is to paint tthe box so then you can go even with ABS or ABS/PC.
RE: Outdoor enclosure
Yes, the material has to be flame retardant.
I don't know "Thermostable (SMC)", what is it?

RE: Outdoor enclosure
How big is this box?
If it's to be injection moulded then I would suggest a FR and GF PBT. Good outdoors being a polyester, dimensionally stable (low moisture uptake), used a lot for higher temp electrical stuff. Reasonable cost.

RE: Outdoor enclosure
What about ABS?We have a similar dimension box made by ABS and to reduce costs we are also evalutating if we can use this one outdoor.
RE: Outdoor enclosure
ABS is crap outdoors (as mentioned, can be painted).
ASA is good, but not sure if FR grades available.
No reason you can't use existing tooling. Parts in either FR GF nylon or PBT will be a tiny bit smaller though.
Of course, PVC is outstanding outdoors and inherently FR. Stainless steel tooling really required though....

RE: Outdoor enclosure
Does PBT need anti UV additives or it is naturally resistant to UV?
RE: Outdoor enclosure
It's pretty good on it's own, but a UV grade would be a bit better.

There's probably thousands of others...
