Corrugated plastic
Encyclopedia
Corrugated plastic or corriboard - also known under the tradenames of Coroplast
, IntePro, Correx
, Twinplast, Corriflute or Corflute - refers to a wide range of extruded twinwall 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 craft knife. Manufacturers typically offer a wide variety of colors and thicknesses (quite commonly 4 mm).
Corrugated plastic is also referred to as Twinwall plastic
.
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-stat, flame retardant, custom colors, corrosive inhibitors, static-dissipative, among others.
This material is commonly used to erect commercial signs and for constructing plastic containers
and reusable packaging. It is widely used in the packaging of automotive and electronic parts as well as agricultural produce.
It has recently found a use among guinea pig
, rabbit
, domesticated hedgehog
and other small pet enthusiasts as a component of a type of DIY cage. Additionally, it is used by members of the remote-controlled aircraft community to build nearly indestructible SPAD (Simple Plastic Airplane Design
) model aircraft
.
At least one manufacturer 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.
