Calenders can also be applied to materials other than paper when a smooth, flat surface is desirable, such as cotton, linens, silks, and various man-made fabrics and polymers such as vinyl and ABS polymer sheets, and to a lesser extent HDPE, polypropylene and polystyrene.
The big difference between the two is that Superadobe uses woven polypropylene bags with barbed wire between the layers, whereas Hyperadobe uses a knit raschel, the same material used in packaging fruit.
The High Speed 1 tunnel linings incorporated concrete containing 1 kg/m³ of polypropylene fibers, of diameter 18 & 32 μm, giving the benefits noted below.
The frit-compression system was adapted from a Solid phase extraction (SPE) column, where a suspension of carbon nanotubes is squeezed between two polypropylene frits (70 micrometre pore diameter) inside a syringe column.
A gunny sack, also known as a "gunny shoe," is an inexpensive bag made of burlap usually formed from jute or other natural fibers, although modern sacks are often made from polypropylene; the "gunny" portion of the name ultimately descends from Sanskrit guṇa, "thread"/"fiber," by way of imperial British corruption of that word's descendants in later Indian languages.
Polyethylene (both LDPE and HDPE), polypropylene, and polystyrene (including HIPS) have all been used successfully with lever-actuated benchtop injectors.
Polypropylene is a polymer synthesized in 1954 by Nobel prize Prof. Giulio Natta, immediately becoming a worldwide success of the Italian technology.
Polypropylene was invented by an Italian scientist, Giulio Natta, in 1954.
Polymers which have been around, and which are in current widespread use, include carbon-based polyethylene, polypropylene, polyvinyl chloride, polystyrene, nylons, polyesters, acrylics, polyurethane, and polycarbonates, and silicon-based silicones.
The fibres used for making the fabric are of high tenacity like Jute, Glass Fibre, Kevlar, Polypropylene, Polyamides (Nylon) etc.
