Ordlista

Här är beskrivningar på förkortningar och termer som förekommer i pappersindustrin.


AOX

Absorbable organic halogens.


BEK

Bleached Eucalyptus Kraft pulp.


BHKP

Bleached Hardwood Kraft Pulp.


BOD

Biological Oxygen Demand, biological method for measuring oxygen-demanding substances.


Bulk

Volume, inverted value for density expressed as cm3/g.


COD

Chemical Oxygen Demand. Chemical method for measuring oxygen-demanding substances


CTMP

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.


ECF

Elemental Chlorine Free. Sulphate pulp bleached using chlorine dioxide, instead of chlorine gas.


EPIS

European Pulp Industry Sector.


SCM UB

Timber measured under bark, used to measure raw timber.


CHEMICAL PULP

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.


Latency

The deformed condition of pulp fibre.


Lignin

Polymer compound consisting mainly of phenylpropane units; the main binding agent for wood fibre. It comprises about 1/3 of the wood.


MECHANICAL PULP

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.


LWC

Light Weight Coated. A type of coated paper often used for catalogues and magazines.


NBSK

Northern Bleached Softwood Kraft: bleached longfibre sulphate pulp. The leading indicator of world market prices.


Norscan

Opacity

Degree of opaqueness.


GROUNDWOOD PULP (SGP)

Mechanical pulp based on roundwood as a raw material.


SHIVES CONTENT

Proportion of unseparated fibres found in the pulp.


SULPHATE

Method for producing chemical pulp.


SULPHITE

Like sulphate, but using a different cooking technique, different chemicals and with a different chemical recovery.


TCF

Totally chlorine-free bleached sulphate pulp.


TMP

Thermo-Mechanical Pulp: mechanical pulp produced using a technique in which the chips are preheated with steam, but without chemicals.


ULWC

Ultra Light Weight Coated. Similar to LWC but with a lower grammage.


UKP

Unbleached Kraft Pulp, unbleached sulphate pulp.


GRAMMAGE

Weight of paper per surface unit, expressed as g/m2.
