Help needed with paraffin chloride 52! !
Thread Content
Hello, may I ask what additives are used after the production of paraffin chloride 52, and which stabilizer is the best to use? The downstream customer deals in PVC transparent pellets; how can we make the pellets produced by this customer more transparent? Thank you so much! ! ! ! I
Any heat stabilizer will do. But your requirement is rather complicated; in the case of transparent products, organotin and thiol heat stabilizers can theoretically be used. Dibutyl tin laurate is a good choice; it provides thermal stability and light stability, as well as having a plasticizing effect. However, the cost will be relatively high. You can mix it yourself.
I’ve found the reason for the insufficient whiteness: it’s due to low temperature resistance at the initial stage; the color turns slightly yellow at 150 degrees. I’m asking how to improve this temperature resistance, excluding the option of adding organotin compounds
