Due to a refined mixing process of the raw materials.
Exact and constant shape.
Each individual length of rubber is tested.
COMPOUND – PREPARATION
Rubber-compound-density is measured in gr/cm3.
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.
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.
The rubber is extruded as a pre-form; it is formed as a rough shape of the final product.
Linen is positioned on this rough form; it will act as a stabilizer for the cushions after 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.
This is measured with a durometer at 3 positions on each length.
Is measured on a rebound-tester according to the Klematch method.
Colour must be uniform.
4 samples per batch are tested for aging-resisting properties.
Union Mondiale de Billard (UMB) and Billiards Industry Supplies (BIS), signed an agreement regarding the exclusive use of VECTOR Rubber Cushions, marketed by BIS, in all UMB Calendar Events, such as World Cups, World Championships and Tournaments, sanctioned by UMB, starting from January 1st, 2018.
