PVDF Film Anti Corrosion Film Laminated Film Waterproofing
Membranes
Description:
Weather Resistance Film is composed of PVDF film combined with PET.
PVDF film not only
has good chemical corrosion resistance, high temperature
resistance, oxidation resistance
and UV resistance, but also has strong wear resistance and impact
resistance.
Anti Corrosion Film has high fading resistance and anti-ultraviolet performance in
harsh
environments. After compounding with PET film, it increases the
strength and meets the
performance requirements of waterproof membranes.
PVDF Film is specially designed for waterproofing industry, which
shall substitute
conventionalexposed waterproofing material including the film for
waterproofing membrane
and corrosion butyl tapes.
It also has cost effectiveness, and lasts over 25years of weather
resistance.

Weather Resistance Film Application:
Metal roof renovation: On the old roof metal plate, the F508-butyl
waterproofing membrane
is fully adhered to the original old roof metal plate base layer to
form a roof system with a
complete waterproof layer.
Photovoltaic roofing: UF508 waterproofing membrane has the same
life as photovoltaic
modules and can replace conventional PVC and TPO waterproofing
membranes.
Main Fields:
As a new material field, functional films are also one of the top
ten key fields of Made in China 2025,
and the awareness in the market is increasing. Nowadays, functional
films are not only used in the
construction field, special packaging, tape, label, automobile,
electronics and other industries,
but also in the fields of film filtration, air permeable film,
graphene heating film, insulation film,
Anti-UV film, biodegradable materials etc..
UPASS, as a leading domestic deep cultivator of polymer functional
films, has also entered a stage
of rapid development. We believe that UPASS will enter more
application fields of polymer films in
near future.
