STYRENE BUTADIEN RUBBER (SBR)
- Rubber or SBR rubber is a synthetic natural rubber suitable for use with weak organic acids and moderate chemicals.
- Not suitable for strong acids, most hydrocarbons and ozone.
- Common use in joints and coatings in general.
Formats
- Thicknesses from 0.5 to 8mm: 1,400mm x 10,000mm rolls
- Thicknesses from 10 to 15mm: 1,400mm x 5,000mm rolls
- For plates and cut-to-size we adapt to the needs of the client: under plan, according to the standard, outside the standard, … all the possibilities.
