Thermal Insulation for Plastic Extruders

Hi Nelson,

I think that 'mineral wool" would fit your application:

Thickness will determine the rate at which you will lose heat, so choose accordingly. Hopefully, you have delivery there for McMaster-Carr products.

I'm sure you can get this material at many other places.

Best of luck!

I've tried mineral wool before. It tends to pulverize in the long run due to vibrations. The woven type blanket works better for me.

My friend in India mfg such fabric for high temp insulation for furnace cables etc. If you are interested please send me your requirement with specs then I will ask him to send you quotation.

Requirements would be 300-500 degrees celcius working temparature. I will cut the blanket myself. Are they woven? How thick?

My friend wants to know the size of fabric required by you and quantity. He has confirmed he will supply woven fabric with wool sandwiched to prevent heat loss. Please send me reply on my e-mail sureshsharma@yahoo.com.

Thanks. Can you laso post the website of your friend so i can also browse other items or options as well.

many thanks.

My friend's name is Niranjan Naayak he is Managing Director.

Viewed it. Thanks. the glass fiber reinforced ceramic fiber cloth (w/o aluminum foil, i think would suit me fine. How much does a roll of 1000mm @ 30m/roll of different thickness would cost...?

My friend has quoted for ceramic cloth with fiber glass 1000mm wide 2 mm or 3 mm thick @ $10/- per mt (for both thicknesses) approx. Prices are on basis of F.O.B Mumbai, India.If you are interested then please let me know so that he can send you detailed offer by e-mail. Please let me know your e-mail address.

Hi Nelson,

Please let me know if have already installed the thermal insulation blanket on hot chamber of extruder?. Could you save the energy due to above blanket installed by you?.This information would help others in similar applications.

Hi. I have not yet installed or purchased the blanket. Still waiting for quotation from a friend. Could you email me exact quotation and dimensions.

By the way, I'm still looking for a suitable LPG controller with flame detector. I'm looking at the controller from LPG fired ovens. With keep you posted.
