Foam Core Board (6mm Depron / Biofoam sandwiched between two layers of micro fine plastic sheets) available for sale from Guwahati. Local pick up only. Shipping will be HIGH via DTDC as they will calculate volumetric weights.

Price : Rs. 45/- per sq.ft.
Max size available : 4ft X 4ft.
Colour : White
Weight : 35grams / sq. ft. (approx)
Minimum order quantity 16 sq. ft. (1 piece measuring 4ft X 4ft).

Extremely rigid and great for making full profile fuselages and wings. I think this is also known as Sturdy Board in the US.

Please PM me your requirements.

Regards.

This is what it looks like (2 sheets one on top of the other).

Also spoke with DTDC, volumetric rates for 8 - 10 sheets of 2ft X 1 ft size, packed with Bubble tape and coroplast on either side will cost Rs. 800 approximately. Thus this consignment will cost a total of Rs. 1700/-. (Rs.45 X 20 Sq.Ft + Rs.800/-).

Thanks Sir. PM sent.

VC · June 14, 2012, 10:48:03 PM

Is this product available anywhere else in India? If so, at what price? I fear that I am being charged high by my supplier for transportation to Guwahati, Assam.

The third picture is the actual stuff. It is NOT Polymer sandwiched between Depron, but the other way around. It is 6mm Depron sandwiched between 2 sheets of acid proof, gossamer thin polymer.

AEROVISHWA · June 14, 2012, 11:39:07 PM

i will upload some pics tomo....! by eve..!

VC · June 15, 2012, 02:33:43 PM

Vishwa, any luck with the photos?

AEROVISHWA · June 15, 2012, 08:23:01 PM

yes sir got some pics....!

there is a layer of polymer on top, in center and at bottom....

sorry for quality of the pics... that happed for 2 reasons
1> size restrictions on the forum
2> simply because my camera sucks.....

VC · June 15, 2012, 08:57:05 PM

What thickness is this? And is this Depron / Bio foam sandwiched or is it something else? Also do you have any idea what it would weigh per sq.ft.?

I doubt if there can be so much of a price variance for the same product (Rs.8.33/sq.ft. Vs Rs.45.00/sq.ft.)...................

AEROVISHWA · June 15, 2012, 09:37:23 PM

its bio foam...! send me your address... will send u a sample piece...

looking at the price(its six times the difference)..! i may be wrong in judging...! u are the best judge as u will have both to compare..!

VC · June 15, 2012, 09:54:34 PM

Thanks, if it is different, I will send you back a piece of what I have. Sending you my address by PM.

AEROVISHWA · June 15, 2012, 10:09:02 PM

Ok guys I received the sample sent VC today.
Updates follows.

it was 5 mm thickness ( may be because it was sample). 5 mm is good but Defenitly would also prefer a 6 mm though.

Its defenitely biofoam ( But it felt more denser than the usual bio foam that was after the film was removed from both sides. I have no means to ratify it though) but it was sandwitched between two sheets of polyfilm which was more stiffer and thicker than oracover or monocoat.

It is pretty stiff even with the film removed but with the film on both sides it is like a biofoam given a monocoat cover strong like a board without the weight component of a board.

With film on it can be painted with variety of paints not possible earlier ( with due care to avoid contact with foam thorough accidental puntures and foam edges)

Its strong and shielded enough (protect foam from oil spray) to make a glow model. You have to insulate/ sheild/ offset the foam from heat of engine though.

Defenitly worth a buy

Sandy, thanks for the expert advice, it will help a lot and I am a relieved man today! Pl let me know your requirements.

To all. Sandy and Gusty were also sent samples of the pieces that I received from AeroVishwa along with the Foam Core Board.

Regards.

AEROVISHWA · June 30, 2012, 10:43:41 AM

VC sir i am waiting for my sample...!

the sample i send i available in any thickness.. also u get sheets of 4ftX6ft...
given u the address and contact no...can check out with him...!

@sundaram sir: could u please differentiate the reviews on my sample and VC sirs...??

sundaram · June 30, 2012, 10:53:36 AM

Usually the biofoams which we have been buying are all a sandwiched layers of thinner foams to arrive at the desired thickness. Like a 6mm foam is two layers of 3mm stuck together to arrive at 6mm.

This one is a single sheet of 5mm foam without layers. It might be the main reason for its stiffness and strength.

Further this is available in size of 4'x8' unlike other biofoam sources which is 100cm x 60cm max. it gives you option to make one piece longer wings, bigger flying wings.

VC If you can manage to get it shipped in larger sizes it would be nothing like it.

@Aerovishwa I am collecting you sample today will review the comparison too. I am sure your's is a plain biofoam available in any thickness in layers. For the people who have a biofoam sources close to home I agree the pricing here is on the higher side. But if I compare to the rate at which I have bought biofoam from forum members here then it seems OK.

VC · June 30, 2012, 11:35:15 AM

Sandy - 20 sheets @ 4'X4'
Gusty - 20 sheets @ 4'X4' - Modified after Post # 19
Self - 10 sheets @ 4'X4'

Order confirmed.

rcpilotacro · June 30, 2012, 11:46:35 AM

VC · June 30, 2012, 11:47:49 AM

OOOOPSIE!

sundaram · June 30, 2012, 03:40:06 PM

Aerovishwa I have received your sample of 8 mm bio foam as well as 4mm laminated on one side.

Firstly the eight mm is a biofoam of two layers of 4 mm stuck together. Which could be separated if you could probe the joint.

The four mm is two layers of 2mm biofoam again and one side lamination was transloucent but not the same material on VCs sample. Yours is easily tearable, whereas VCs sample has a thicker film with more strength. Though its also tearable but defenitly with more effort.

Main thing is VCs sample even after its peeled its more denser and stiffer the biofoam which we all have bends easily.

Aerovishwa can I know how much a 4'x4' double sided laminated bio foam of 5 mm and an unlaminated 8 mm costs at your end

VC · July 01, 2012, 12:29:08 PM

Sandy/Gusty - Got your confirmatory text this morning. Confirming your orders for 20 sheets each. have decided to go ahead with 10 sheets for myself too.

Got surprised. I am now making Micro-Cub with White coro. Single layer wing.
Have to wait till last sunday as My SDCard filled and no spair then. (I dont erase but preserve them).

Thanks

VC · July 01, 2012, 12:41:54 PM
