Master batch
A preliminary mixture of two or more compound ingredients for purposes of more thorough dispersion or better processing, and which will later become part of the final compound in a subsequent mixing operation.
Maximum horsepower
The highest power requirement.
Maximum ply
(1) The maximum number of plies permissible that will permit for satisfactory troughability; (2) The maximum number of plies permissible to satisfactorily operate around a pulley of a given diameter.
Maximum safe working stress
The greatest tension at which a belt should be operated.
Maximum tension
See tension, maximum.
Mechanical fastener
Any mechanical device used to join the ends of belting.
The transfer of an ingredient in a rubber compound from one layer to an adjacent layer or to the surface.
Migration stain
When staining occurs on the area of an object adjacent to the rubber article it is known as “migration stain”.
Growth on organic matter produced by fungi, generally in textile components of rubber articles. Usually causes deterioration.
Mildew inhibited
The article contains material to prevent or retard mildew.
A machine with two horizontal rolls revolving in opposite directions used for the mastication or mixing of rubber.
Minimum accelerating time
The least time allowed to accelerate a conveyor belt from rest to normal speed without exceeding its maximum safe working stress.
Minimum braking time
The least time allowed to decelerate a conveyor belt from normal speed to rest without exceeding the maximum safe working stress or causing the belt to double up on itself.
Minimum ply
The least number of plies that will support the load on a belt without damaging deformation.
Minimum pulley diameter
The smallest pulley diameter around which a belt is recommended to operate.
Minimum tension
See tension, minimum.
Mirror finish
A bright, polished surface appearance.
See compound
Modified grab test
A tensile test for woven fabric using specimens wider than the jaws holding the specimen cut midway between the jaws to the warp yarns held by the jaws. Minimizes warp yarn popout experienced by raveled specimen test.
Modulus of elasticity
The force divided by the percent elongation (divided by 100) to cause the elongation.
Modulus, belt
The force per unit width of belt required to produce a stated percentage of elongation.
Moisture regain
The re-absorption of water by a textile.
Mold edge
A belt edge formed during vulcanization by curing in a mold or against edge irons.
Mold lubricant
The material used to coat the surfaces of a mold to prevent the rubber adhering to the metal during vulcanization.
Mold mark
An indentation or embossment on the surface of a molded product caused by irregularities in the mold surface.
Mold register
The means used to align the parts of a mold.
Mold release
See mold lubricant.
A single extruded strand of material (i.e. a fishing line).
A relatively simple compound which can react to form a polymer.
Mooney viscosity
A measure of the plasticity of a polymeric compound determined in a Mooney shearing disc viscometer.
Abbreviation for Mine Safety and Health Administration.
MSHA flame retardant test
Flame test procedure for underground conveyor belting prescribed by the Mine Safety & Health Administration of the U.S. Department of Labor.
Many extruded fine strands of material grouped together.
