APPLICATIONS
PVC as sold in resinous form is usable by incorporating suitable additives to convert the resin in a form which it can be processed into useful end product.
As material for the ultimate product,compounded PVC can be formed by allmost all the standard plastics processing techniques including calendering,extrusion,
injection and compression molding,blow-molding,rotational molding,slush and dip-molding, solution casting, electrostatic spray,fluidized bed coating.
Depending on plasticizer content level incorporated into the vinyl plasticizer compound, a typical vinyl end product can be obtained from semirigid(al low content level of plasticizer)to flexible or highly flexible products(at high and very high content level plasticizer).
158100 and 161100 are recommended for formulating vinyl
compounds suitable mainly for processing by extrusion(of semirigid profiles-very thin wall pipes and tubes,siding,flat and corrugated plates,floor covering, window shade, records, credit cards) by blow-molding (of blown bottles for food or general use)
or by injection(of fittings,etc.).
