Well, shipping costs wise, they quoted me 34,20€ for 59 kilos, plus 18€ for packing. That's to my door 300km away from them aproximately.
It would be nice to find out more avout longevity. And also, i would love to know what the binder is.
Beacause vacuum forming a tube should be pish easy.

Pyrophile, i am waiting for the answer from the producer. I will also try to ask about the conditions around polish producers. and i do not think you should be worry with shipping cost. I think that every country should have their producers, since it is quite commonly use as insulation in many indystries.

Chatting to a UK supplier he mentioned they are not designed for longevity, in fact some are for single use only. He also quoted a binder but I can't recall the name so I'll have to ask again in the new year.

The vaccum formed tubes are superWool 607HT made, rated at 1300°C, withstanding 1200°C on long time burning. They give charts for maximum temps for long time burn.
Write on Google :
Morgan thermal ceramics download "fact sheet 3"
and the third page of this pdf is the good one. Sorry I did not succeed another way!

I got a first price : diameter 130mm, thickness 10mm, length 250mm ,
4 pieces ( that is a cylinder of 1 meter long) : 180 euros! (shipping costs not included)
Too much for me! How much will it be for a 200mm cylinder?!

Wow. Quite expensive. I have found nice suplier but in China. www.alibaba.com/product-gs/1597062578/Vacuum_Formed_Ceramic_Fibre_Shapes_China.htmlwhat is interesting about that product: • Applications that require high-temperature toughness,high strength from the load-bearing areas • For high air flow, mechanical damaging large areas of Industrial furnace wall lining, door and roof seals • Construction, fire doors, fire wall fire insulation • Combustion chamber insulation Do we have anyone from China here on a forum? Anyway based on those research i will send the question to the polish producer here. From the first talk that we had i found out that they use different kind of binders. Organic and non organic. Organic ones likely to burn out while the innorganic will stay looonger. So during the production process they should use inorganic binders. So when i will get the reply i will post the results. |

Guys, if you can't find this stuff cheap, making one heat riser out of superwool and binder around a PVC tube shouldn't be too hard. Even if you want to vacuum form it, a little fridge pump, and tapped plastic should do the trick. Myself, i think i'll stay in the refractory tubing surounded by rockwool or vermiculite. May be not as lightweight, nor as fancy. It has thermal inertia, while superwool risers have less. But it's cheap!

Forming superwool around a PVC pipe was exactly what I asked peterberg about just the other day, strange world.

Satamax,
What is exactly a binder, where do you find it?
Thanks

Matt, you mentioned riser sleeves in another thread. Is this what you are referring to? I've found a supplier here in the UK that does them in 152mm (6") inside diameter x 150mm (6") tall x 8mm wall thickness. Are yours a similar size? Reasonable @ £2.50 each, but trouble is they come in boxes of 27. morticcio: Can you please let me know who this supplier is? I'm interested in using them (reinforced) for a 5" system. Thanks. |

Hey there.
I am just coming back from Belgium when i could meet Joris Pouls, who is using those Vacuum Formed Ceramic Fibre heatriser for quite a while. I was lucky to build two stoves with him and place two heatrisers, so i can share some of the experience.
First of all what he told me that they where made especially for him in the factory. They are rated 1460C resistance and more inorganic binders has been add to made the more rigid. Also in new edition they add some clay for him while baking it.
It is very nice and durable material. nice to work with and of course with great isolation value. The price is just quite high. 3 pieces that formed a rises where about 80 euro each. So 240 total. I will have to check the price at a factory in Poland and hope the prices will be less expensive.
Here are some pictures from the build:
OH>>> Forum exceded the upload limit???
i will have to work on it and place the photos on some other site.
