VESTOLIT B 7090 Ultra

Polyvinyl chloride for paste processing

VESTOLIT B 7090 Ultra is a paste-forming micro-S-PVC copolymer which is suitable for producing pastes with almost Newtonian flow.

The general properties of B 7090 Ultra are particularly suited to the production of low-fusion temperature pastes for compact applications and for mechanically expandable foams.

The vinyl acetate content of approx. 5% in VESTOLIT B 7090 Ultra enables significantly improved fusion characteristics compared with comparable homopolymers. Due to its low viscosity and the excellent storage stability,

B 7090 Ultra is recommended for all applications requiring a reduction in fusion temperature over conventional processing conditions. Consequently, the main application fields are: sealing compounds for cars, the coating of temperature-sensitive substrates and adhesive layers. The good mechanical foaming properties of B 7090 Ultra also enable its inclusion in low-fusion temperature back foams in the CV field.
