VESTOLIT B 6021 Ultra
Polyvinyl chloride for paste processing
VESTOLIT B 6021 Ultra 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 Ultra has both good fusion and foaming properties at low temperatures.
Due to the low K-value of 60, VESTOLIT B 6021 Ultra 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 6021Ultra due to the low fusion temperature. B 6021 Ultra can be mechanically foamed and also has excellent drum release properties.
