- Does 100 % Gamma-Butyrolactone exist ?
- Is there a difference between german GBL and chinese GBL ?
- Why is that ?
- Why does your company sell Chinese quality also then ?
- How do u know all listed resellers in google sell the same imported GBL from China ?
- Does 100 % Gamma-Butyrolactone exist ?
- No, there is no manufactury on this world that could produce that.
- Is there a difference between German GBL and Chinese GBL ?
- Yes. Off course is German GBL produced in Germany and Chinese GBL is produced in China. But our german manufacturer can guarantee their produced GBL is 99,7% pure, and chinese GBL suppliers do also guarantee that but they more pretend to have 99,9% purity.
- Why is that ?
- Imagine under wich circumstances a Chinese manufacturer (located in China) is allowed to produce. In China they don't have the very severe law-restrictions, constant production monitoring,our German manufacturer has to produce with.
Why does your company sell Chinese quality also then ?
Because some of our customers aways cleaned with chinese GBL and are very satisfied with it.
How do u know that the resellers U have listed all sell the same imported GBL from China?
That is because we ordered a sample of 1000ml Gamma Butyrolactone at all European resellers, wich we have send to a certificated laboratory for a deeper analysis.
Their conclusion was that that all listed companies import their Gamma-Butyrolactone from the same manufactory in China as we do.
Their second conclusion was that the concentration (or purity) off the Chinese GBL didn’t level 99,99%, but was maximal 99,23% pure Gamma Butyrolactone.
The cleaning power is not effected or less with GBL that has lost of it's purity.
