| Vestolit B 6021 |
 |
Polyvinyl chloride for paste processing.
Vestolit B 6021 is a paste-forming micro-S-PVC homopolymer which is suitable for producing low viscosity pastes with almost Newtonian flow and good storage stability.
B 6021 has both good fusion and foaming properties at low temperatures.
Due to the low K-value of 60, Vestolit B 6021 provides faster fusion even at low temperatures and produces a fine cell structure when using particular kicker/blowing agent combinations, and/or fast kickers.
The product is therefore particularly well suited for back coat foaming of CV floor coverings.
In both compact and foamed wallcoverings, high embossing speeds can be realized with B 6021 due to the low fusion temperature.
B 6021 can be mechanically foamed and also has excellent drum release properties. |
