Just had a long conversation with Mr. Chetan Delhiwala of

Ankita Commercials
Shop No.8, Reliance Complex,
Troop Bazar,Hyderabad
Pho.040-66743217 / 66105856
web: www.jjgroup.co.in

Available : 24mm thickness sheets 122 mm X 61 mm (4 feet X 2 feet)
Price per carton of 16 sheets (they are not authorised to sell loose) = Rs.3240/-

We ideally need 6mm sheets. Thus from each sheet, we can produce (using hot wire) 4 sheets approximately. Taking wastage into account, let's say, we manage 3 sheets from each 24mm piece. Thus, we are talking about 48 - 64 sheets (take an avg of 50 sheets) of wonderful blue styrofoam for Rs.3240/- (price per sheet will work out to Rs. 65/- approx)

The people staying close to Hyderabad are lucky, as they can save on transportation. In my case, air freight is working out to Rs.1100/- or so giving me a cost of Rs.85/- per sheet if I can produce 50 pcs of 6mm from the pack of 16 pcs of 24mm.

Go for it guys!

I think the key lies in finding local suppliers of "" STYROFOAM, the blue extruded polystyrene (XPS) foam""

I think if it is available in Mumbai, Hyderabad then it should be available in Chennai and Bangalore as well.

Will check out and update if I come across something .

As VC sir give a gr8 break out it is good for locals. but buying that much whole lot and consuming self will be a tuff job.........

Hi Guys,
This stuff is used in insulation here and is perfect for cutting wing cores out of it.
Good for sanding and shaping, cuts easily with hotwire cutter. Denser version of thermocol which can be sanded easily. It is available at large builders merchants as 50mm or 100mm thick 2.5mt x 1.50mt sheets.
I use it for repairing foam wings. This cannot beat EPP though.
EPP is much more forgiving in hard landings. If you want to build something out of this, you will have to use reinforcing tape from HK and have a carbon/ bamboo spar. This is very rigid.

You will be waisting time and money trying to build from 6mm blue foam. Forget it.
This is used as a 24mm thick to cut wing cores.

Blue foam i will only consider it good for making patterns for fiberglass cowl, wheel pants. Blue foam due to its fine grain quality is great for making patterns. 

i have seen those blue styrofoam in my school days    
i even used it for a a small project in my school.  
i got  it of a retailer near me about 10 yrs back
sadly now no stationery stores stocks those things here
infact 5yrs down the line we were told by the school not to use them as well as thermocol  
since they are not biodegradable
i think the sheet was about 3*2 feet long i got it for about  :Rs:50

Not blue but same product is available at Kolkata which is light green colour. Like blue foam it is also weight 32kg cubic meter as per the company guy. I have even collected one piece sample block to see how it works with hotwire and laser cutter.

Rajib bhaiya where did you get it in Kolkata and what is the price?

PM me your e-mail id, I want to send you one PDF file about this foam which is 1.92MB.

Guys what happened to this thread we need to talk about this STYROFOAM STUFF.

http://www.rcgroups.com/forums/showthread.php?t=359312       Look at the Mirage 2000 in this link it is of styrofoam.

Hi friends,
My 2c if I may; I have seen 2 varieties of extruded poly styrene in Kolkata. One is light green and one is light blue. The light green is made by Supreme Petro chemicals in India and the blue one is Dow.  Of what I have seen the green one is harder or stiffer compared to the blue one which may make it more brittle. The blue one its slightly softer and more flexible than the green one. None is sold loose. I prefer the green variety.
Thanks.

Is anyone going to supply it to me?

Seems like no one is serious about build material used for RC Planes that is why i do not get replies in a proper manner.This is the link. Need to talk to these guys=http://www.kknag.com/exp_polystyrene.htm       And hope something turns out to be there.BTW this is EPS=Expanded Polystyrene and Expanded Polypropylene (EPP) Used for making Rc Planes.I am searching for more.

http://www.devifoam.com/sheet.htm     One more source lets see if this works.

http://www.exportersindia.com/rahilfoam/products.htm?slno=21699          Another Source. Lets Try Again.

Since you are in Mumbai, the best way to source styrofoam is to search for Distributors/dealers of either Dow Chemicals or Supreme Petrochem, I source my styrofoam in Kolkata from Supreme Petrochem and since the company is based in Mumbai, you will definitely be able to source it there.

Thanks.
