CONSTANT RE-BOUND
Due to a refined mixing process of the raw materials.
QUALITY SHAPE
Exact and constant shape.
100% TESTED
Each individual length of rubber is tested.
COMPOUND – PREPARATION
DENSITY
Rubber-compound-density is measured in gr/cm3.
TENSILE STRENGTH
The compound is tested on a traction-machine and the result is expressed in MPa.
ELONGATION AT BREAK
This is measured also on a traction-machine and is measured until break as a percentage versus the initial length.
VISCOSITY
This is measured with a “visco-meter” and is expressed in “Moony-point” units.
VULCANISATION – PROCESS
RHEOMETRIC COMPOUND CONTROL
Temperature-stability is extremely important in order to get the optimum end-result, therefore it is monitored constantly.
PRE-FORM
The rubber is extruded as a pre-form; it is formed as a rough shape of the final product.
TEXTILE POSITIONING
Linen is positioned on this rough form; it will act as a stabilizer for the cushions after moulding.
COMPRESSION MOULDING
The rough shape is placed in a compression mould where it will be heated while being compressed during an exactly defined time. During this process the elastomer molecules will be cross-linked so that the rubber gets its required stiffness but retains its extensibility.
TESTING
SHORE HARDNESS
This is measured with a durometer at 3 positions on each length.
REBOUND
Is measured on a rebound-tester according to the Klematch method.
VISUAL ASPECT
Colour must be uniform.
AGING
4 samples per batch are tested for aging-resisting properties.
standard lengths:
2120 mm, 2320 mm, 2560 mm,
2850 mm, 3000 mm
