Range of extruded twinwall plastic-sheet products
Corrugated plastic
or
corriboard
? also known under the trade names of Biplex,
Cartonplast
, Polyflute,
Coroplast
, FlutePlast, IntePro, Proplex, Correx, Twinplast, Corriflute and Corflute ? refers to a wide range of
extruded
twin-wall plastic-sheet products produced from high-impact
polypropylene
resin
with a similar make-up to
corrugated fiberboard
. It is a light-weight tough material which can easily be cut with a
utility knife
. Manufacturers typically offer a wide variety of colors, thicknesses (quite commonly 3, 4, 5 mm), and weight (measured in grams per square meter, or GSM).
Chemically, the sheet is inert, with a neutral
pH
factor. At regular temperatures most oils, solvents and water have no effect, allowing it to perform under adverse weather conditions or as a product component exposed to harsh chemicals. Standard sheets can be modified with additives, which are melt-blended into the sheet to meet specific needs of the end-user. Special products that require additives include:
ultra-violet
protection, anti-static,
flame retardant
, custom colors,
corrosive inhibitors
, static-dissipative, among others.

of air-to-air
heat exchangers
(used in
heat recovery ventilation
) uses a fused stack of sheets of this material alternating with spacers made of the same material as the heat-exchange medium. One air stream passes through the corrugated channels in the interior of the sheets, while the other passes between the exterior layers of the stacked sheets.
