Flexalen Training in Thailand

It's again the attempt to educate our prospects to understand more of our "Pre-Insulated Pipe", or so called "Flexalen".

The event was held during 1-5 August 2011 focused on new customer from Hong Kong, and the existing customer from Australia and Vietnam.

Thanks to Mr. Markus Thürnbeck, who has traveled far from Vienna, Austria, to give us all the proper training according to Thermaflex standard.  There are many interesting points to look at which I will add more detail later.

For any of you who is interested in Flexalen, you can try click into the YouTube on the right part of this blog for further info.

"Water Absorption" -- The Real % or else?!

From previous article, I told you how to test the water absorption out of normal insulation sample, with the simple water bucket and so on.  Now, I will tell you a bit more knowledge of how to really look at water absorption.

Normally, we can see in most insulation brochure the water absorption in percentage.  Who does really know what they mean by %?

There are detail to look into when some insulation says they have this or that % of water absorption.  % of water absorption can be looked into 2 scenarios i.e. mass % and volume %.

Take a look at this example:

We have 100 grams of insulation sample (any kind).  We have water at 200 ml.  Then, after a period of time dipping the sample into this amount of water, we notice the insulation sample absorb water at 10 grams (or equivalent to 10 ml).

If you look at mass %, you will then have 10% water absorption.  Why?  It's because the sample absorb 10 grams when compare to its original weight of 100 grams!

If you look at volume %, you will then have only 5% water absorption.  Why?  It's because the sample absorb 10 ml when compare to its original water volume of 200 ml.

Now, you know the fact!! :)
