Här är beskrivningar på förkortningar och termer som förekommer i pappersindustrin.
Absorbable organic halogens.
Bleached Eucalyptus Kraft pulp.
Bleached Hardwood Kraft Pulp.
Biological Oxygen Demand, biological method for measuring oxygen-demanding substances.
Volume, inverted value for density expressed as cm3/g.
Chemical Oxygen Demand. Chemical method for measuring oxygen-demanding substances.
Chemi-Thermo-Mechanical Pulp. Development of TMP, where the mechanical pulp is impregnated with chemicals. Stronger than TMP. The term is used in Europe for both bleached and unbleached pulp.
Elemental Chlorine Free. Sulphate pulp bleached using chlorine dioxide, instead of chlorine gas.
European Pulp Industry Sector.
Timber measured under bark, used to measure raw timber.
Paper pulp produced by boiling raw timber with chemicals. The pulp can be bleached to a higher brightness and a higher strength than mechanical pulp. Chemical pulp is usually sulphate pulp, but can also be sulphite pulp.
The deformed condition of pulp fibre.
Polymer compound consisting mainly of phenylpropane units; the main binding agent for wood fibre. It comprises about 1/3 of the wood.
Pulp produced using a mechanical process for fibre separation and processing. Has a higher level of bulk, stiffness and opacity than chemical pulp. Groundwood pulp, TMP and CTMP/BCTMP are types of mechanical pulp.
Light Weight Coated. A type of coated paper often used for catalogues and magazines.
Northern Bleached Softwood Kraft: bleached longfibre sulphate pulp. The leading indicator of world market prices.
Canada, the United States, Sweden and Finland.
These consist of various phosphorus and nitrogen compounds which have a fertilising effect in the recipient.
Degree of opaqueness.
GROUNDWOOD PULP (SGP)
Mechanical pulp based on roundwood as a raw material.
Proportion of unseparated fibres found in the pulp.
Method for producing chemical pulp.
Like sulphate, but using a different cooking technique, different chemicals and with a different chemical recovery.
Totally chlorine-free bleached sulphate pulp.
Thermo-Mechanical Pulp: mechanical pulp produced using a technique in which the chips are preheated with steam, but without chemicals.
Ultra Light Weight Coated. Similar to LWC but with a lower grammage.
Unbleached Kraft Pulp, unbleached sulphate pulp.
Weight of paper per surface unit, expressed as g/m2.
