Polyvinyl chloride for paste processing.
Vestolit B 7021 is a paste-forming micro-S-PVC homopolymer which is suitable for producing low viscosity pastes with almost Newtonian flow.
The properties of B 7021, enable it to be used universally for compact and foamed coatings of any kind as well as for dip coating and casting processes.
Vestolit B 7021 may be used whenever low viscosity, good storage stability and low moisture absorption are called for.
The product is particularly well suited for rotational moulding, dipping and casting processes.
In coatings, it has the added benefits of trouble-free handling in contact fusion(e.g. drum gelling of glass-fibre mats).
For mechanical foams, B 7021 may also be processed using both soap-based and silicon-based foam stabilizers. |
