Hello people,
Is Polypropylene (PP) good for scratch building and detailing?
We commonly use Styrene and I'm just wondering if PP is any better.
Thanks ya'll

Well according to Wiki, it's a bad idea... Why?
As quoted from a Wiki search:
"Degradation
Polypropylene is liable to chain degradation from exposure to UV radiation such as that present in sunlight. Oxidation usually occurs at the secondary carbon atom present in every repeat unit. A free radical is formed here, and then reacts further with oxygen, followed by chain scission to yield aldehydes and carboxylic acids. In external applications, it shows up as a network of fine cracks and crazes which become deeper and more severe with time of exposure."
Thanks to Wikipedia ;D

That' deeeep man..
So tell me, what could be the type of plastic used to make credit cards, ATM cards, pre-paid cards and the likes? Since styrene is hard to get here, I'm planning to get "these" instead.

I don't know what plastic they are made of but in terms of using them I will not suggest it because I've tried using the older and thicker prepaid cards, you can only use them on areas that is not used or seen a lot like covering open spaces in an 1/100 HG kit. But in terms of using it elsewhere where you need glue, don't bother, this plastic don't stick properly with plastic model glue and the other glue will do more harm than help you with your kits' plastic.
Try going to Lil's, they have different gauges of the white styrene which is preferred by most modders.
Good Luck ;D

You're right, bro. I've tried using these prepaid cards and you have to sand it and wipe lacquer thinner with a piece of cloth or whatever have you to make super glue (talking about "super" it's really not super after all) adhere. But if you want to break the two pieces apart you may still do so without much effort. It's good to use them in places where you will not put tension or else it might come off.. Last time I ask somebody to STC they don't have stocks of styrene. I'll have it checked at Lil's. By the way anybody can tell me the thickness of these prepaid cards?

Sorry I didn't notice you're in UAE... my bad...
You can look for other brands of styrene as well like in other hobby shops that cater to tanks, planes and cars...
Prepaid cards come in paper like thickness and sometimes even thinner. For thicker material, you can also use SIM card er... card. The ones that holds the SIM card when you buy one...
You can also use those plastic trays, but just make sure they don't come in contact with a glue that will eat them up in seconds... They also come in various thickness...

Where can I get styrene on philippines? As mentioned before... If you're in Manila you can go to Lil's in Megamall and Park Square 1 Makati, or the hobby shop in Ali Mall Cubao. Thickness varies thus price vary a lot specially when it's a thick styrene. The cheapest are the tubes and I Beam types (because they were basically designed for architectural models and not Gunpla. I don't know if GT supplies them but due to recent events of supplying modeling stuff, you may want to ask them. |
