Raw materials and funcation for PVC foaming board
1.PVC resin
SG-5 /SG-8,SG-7,K 60
2.PVC compound stabilizer
Lead based one pack PVC stabilizer or Ca/Zn stabilizer,
Funcation:Prevent the heat decomposition of PVC resin
3.Chemical Foaming agent, NC/AC
AC blowing agent.NC blwing agent( white blowing agent), AC foaming agent belongs to the exothermic foaming agent,
NC foaming agent belongs to the endothermic foaming agent
4.PVC Foaming regulator ACR901/90/530/100
Funcation: improve the melt strength of the melt and prevent the merger of the bubbles, so as to get the PVC foaming products with uniform foaming. At the same time, it can also promote the plasticization of PVC to ensure that the melt has good fluidity
5.Lubricants processing aid ACR175
Promoting plasticiation, stripping between materials and metals ,keep the material better fluidity
6.Lubricants G60/G74/70S
It is internal and external lubricants promoting plasticization, improving polymer fluidity and improving the surface finish of products.
7 PE WAX
It is external lubricants,Reduce the friction between the polymer and the surface of the machine to prevent it from adhering to the mechanical surface
8.AC -316A OR OA-6
It is high melt point ope wax, have good internal and external lubricants in middle and late processing
9.titanium dioxide Tio2 ,optical brigthener OB
As pigment ,let product more white, and look blue shade
10.Filler
Filler caco3 can inrease strengh of foaming board,can reduct cost of PVC foam board
I had been focus on this field over 15 years. all these material availble, welcome for your product enquiry and cooperation.
