What is the reason for the appearance of crystal points in PVC transparent sheets modified with MBS impact modifiers? ? ? ? Urgent! Is there also a precipitation issue with MBS? Is it a problem with the MBS we’re using? If it’s not possible, what could be the reason?
1. Are there too many PVC fish eyes, and are the crystalline particles caused by insufficient plasticization?； 2. Is the quality of your MBS too poor? Is there no maternity leave?
There might be a problem with your mixer. Precipitation? Is the MBS impure?
Haha, thanks for the reminder. I used to think about MBS all the time, but never considered PVC. MBS is its own product, with no exaggeration or exaggerated claims.
To summarize: 1. Regarding raw materials, do PVC and MBS have many crystal points? If it’s not one’s own product, there will be no crystal particles; this is related to the synthesis process. 2. In terms of processing, what about the plasticizing capacity of the machine? Is it a problem when using another machine, or is it worse?
Only when the quality of MBS is substandard; otherwise, the presence of crystal points in the PVC sheets has nothing to do with MBS. Furthermore, no precipitation of MBS occurs either. It is estimated that your MBS has quality defects.
What about an extruder? Should we consider that as well? Uneven plasticization
