Paraffin put more put less plasticizer is internal / external lubricant

pvc products , the wax is put more plasticizers, put less is internal / external lubricant ?
Paraffin said here refers to the full name of " wax " or " paraffin " ?
I read some of the recipe data , some WSD Titanium dioxide rutile  put more than 20 PHR , put some 0.5 PHR.
2 . Put more than 20 PHR definitely soft products plasticizer use , and that this situation will not have a lubricating effect ? Inside or outside lubrication lubrication ?
3 release 0.5 PHR , is not no use as a plasticizer ? Only as a lubricant ? Inside or outside lubrication lubrication ? And this ratio is only hard copies of articles for the formulation , and not for  WSD Plastic impact modifier the soft goods formulations are typical chlorinated plasticizer . Copies may want to add to the dozens . All adds a plasticizer has the role of lubrication . But within five hardware products , or the need to add additional components within the slide . Added to 20 parts plus without actually depends on the slip process , as well as product performance, such as the current size of the host processing .
 Paraffin is carbon saturated hydrocarbons , petrochemicals inside out , which is used in pvc play a significant WSD Polyethylene wax  role outside the slide , add the amount is generally less than 1 .
 The role of the gap between the two played in pvc processing is relatively large . See you write so seriously , I suggest you book early aspects of pvc look , or online to understand their role under the type of pvc accessories . Easy to understand for the recipe .
