Rohit Gupta,

If you have anyone travelling to or from Guwahati to Kolkata, let me know. Depron 6 mm sheets are available here in Guwahati for Rs. 50/- per sheet ( 1000mm X 500mm X 6 mm)

Cheers!

Ok VC bhaiya thanks. Ill let u know if any of my relatives are travelling to or from Guwahati.

Breaking news for Aeromodellers in Kolkata. After 3 months of hectic search(especially the last 15 days) and agressive googling for Extruded polystyrene or biofoam i have successfully been able to track a dealer who has huge stock of biofoam in kolkata . I together with Kalyan Da have purchased a complete slab of biofoam 80 inches(6 feet 8 inches)  by 24 inches(2 feet) and 100mm thick for Rs 1250. The salesman said that they have slabs of thicknesses 25mm, 50 mm, 100mm in stock. The company is Supreme Petrochem Ltd. (www.supremepetrochem.com), it is based in mumbai and has a dealer in Kolkata.It is located close to Central Metro station. The exact address is 28, Blackburn lane, Kolkata-700012. The name of the building is Rup Bhavan opposite to Shilpa Bhavan, 7th floor. You can also find them on www.justdial.com .However, please note that it is not known as "biofoam" here, those interested should ask for "Extruded polystyrene" .Their stocks are stacked up in the ground floor.Those who need help with the directions may contact Kalyan da. I feel absolutely ecstatic at the moment. Pictures will also be posted subsequently. I really want to thank Kalyan da and Sethji for finding time from their hectic schedule to search for this elusive material.

Here are the pics :

One more pic :

We divided the slab into two sections of 40" by 24", 100mm thick. The material is very rigid and extremely light. I don't know the exact density, maybe Kalyan Da can help me here, but seems to be above 25kg/m^3. Plan to cut sheets of 5 or 6mm thickness. Now excluding about 20% for wastage. We are left with 80mm thickness. If we decide to make sheets of 5mm we can get 15 to 16 sheets from each half. Altogether 30-32 sheets of 40" by 24"(abt 3.3 by 2 feet), 5mm thick. Total cost was Rs 1250. Therefore price of each sheet comes out to be approx. Rs 40  .

Kalyan da is also gifting me a hot wire cutter.

Kalyan da, what is the exact density of the foam?

thanx all u guys...all dese info was of real help to me...

I have come across a green dense foam in chadni market recently. The shopkeeper calls it "Insulation Foam". Its Rs. 320 per sheet of approx dimensions: 2.5feet by 4feet by 1.5 inches. Anybody seen or used this foam? Its light green (Not the dark ones florists use).

I have used white Styrofoam. There is a green version of the Styrofoam manufactured by DOW. Is it the one you are talking about? I would love to have a look. Where in chandni did you find it? Lets go together one day!

also blue foam is available..thats also extremely light and strong but brittle..heard its cheaper in burrrabazar area!

@Rohit: Would you be free this Saturday? I will pm you my phone number. We can meet at Chadni. As far as I can remember, the shop's name was Y.M. Rajbhai. There are a couple of shops in that area. Maybe they stock it too.
@tatum012: Any more details? I have seen the foam florists use. They are very brittle, useless to us modellers..

Does YM Rajbhai really have that foam? The last time I visited, they clearly told me that they do not stock any such material.

Yes I saw it there. They said it was Rs390 for a 10mm thick sheet..

Has anybody bought any of that dense foam lately? i am planning on coming to Kolkata to come shop for building materials
