Polyvinyl chloride for paste processing.
Vestolit B 7521 is a paste-forming micro-S-PVC homopolymer which is suitable for producing low viscosity pastes with almost Newtonian flow and good storage stability.
The product is particularly well suited for paste applications with a low plasticiser content and can be used for coating applications, dip coating and casting.
In the manufacture and processing of pastes, Vestolit B 7521 is distinguished by its low viscosity and low moisture absorption, properties which are particularly suited to rotational casting, dip coating and dip moulding.
In coatings, the excellent drum release characteristics and good contact fusion capability result in smooth surfaces in glass-fibre mat impregnation of CV coatings.
B 7521 may also be processed in mechanical foams. |
