Roll in PVDF GB natural

PVDF is a fluoropolymer for chemicals, related to PTFE plastic but with one decisive difference: it can be welded, glued and machined like an ordinary engineering plastic. That is why whole tanks, vessels and pipe systems can be built in one and the same material, where PVDF takes the aggressive chemistry and is joined together on site.

The material stands up to the acids that knock out most other things, such as sulfuric acid, hydrochloric acid and hydrofluoric acid, even at 60 degrees, and it takes chlorine gas and ozone. It handles 140 degrees in continuous service, far above what ordinary polypropylene and vinyl plastic manage, and it burns slowly by itself with an oxygen index of 44 percent, entirely without flame retardant additives. The density is 1.78 and the material melts only at 171 degrees. Moisture hardly bothers it, around 0.01 percent in ordinary air, so the dimensions stand still.

This product is PVDF on a roll with glass mesh backing, abbreviated GB, in natural color. One half of the glass mesh is pressed into the sheet while the other half sticks out, so that a glass fiber reinforced laminate gets a proper mechanical grip against the back. The supplier states a peel strength of at least 5 N/mm2 for the backed sheet. The roll is used as an inliner in glass fiber reinforced composite tanks, where the fluoropolymer takes the aggressive chemistry on the inside and the laminate carries the load on the outside.
