CPVC Outline
CPVC (Chlorinated poiyvinyl chloride)has become an extremely important plastics in the engineering,it has a lot of merits such as relatively low cost,high hard embrittlement temperature(Tg),high thermal bending temperature ,abtuse(inactive) chemical properties , excellent mechanical strength , no electric conductivity,safest conductibity and smokiness of combustion .
The commercialized production and applications of CPVC was initiated by BF Goodrich Corporation in early 1960,CPVC has received very high appraise in various industrial applications for its high-temperature resistance and perfect chemical reisistance.
In the concept ,CPVC is made from PVC Homopolymer through chloridization , while in the models,PVC and chloridization,while in the models,PVC and chlorine take actions according to the reaction mechanism of free basic radicals ,where can be started up with varied methods like heating and UV power , a common reaction process on the chloridization of free PVC radicals is descriced as below,where RH refers to PVC.
The status and reaction capacity(chlorine) of CPVC have vast difference by the different modes of chloridization . Compared with 63~69% as per general CPVC ,the chlorine content of basic PVC of this CPVC has been upgrade from 56.7% to 74% . Thanking to the increase of the chlorine content ,the hard embrittlement temperature of polymer(Tg) will be greatly boosted , due to the increase of molecule weight of basic PVC ,Tg under same contentwill be also a littleupgraded.
CPVC Product uses the standard
CPVC Series Standard Pipe Materials is produced as per GB/T 18993.2-2003 , Vicat Softening Temperature as per GB/T8802-2001 , Dart Drop Impact Test as per GB/T14152-2001, the others according to ASTMF441, F439 ,F437, as well as DIN8079,DIN8080,ISO 15493-1.
