Guide to table tennis rubbers:
SPEED: The ability to easily create faster ball speed based on a rubber's power created by the sponge rebound force and top sheet hardness.
Higher speed rubbers also called faster since they produce faster shots. Speed differences between rubbers are greater with 2.5 or 2.0mm sponges. Attacking Players usually prefer the fastest rubbers while defensive players may prefer slower rubbers.
SPIN- The ability to create stronger spin is determined mainly by the composition and quality of the top sheet.
POWER FACTOR-The sum of spin and speed ratings. Powerful rubbers combine high speed with strong topspin to create maximum attacking power.
WHAT IS RE-GULE EFFECT: Not all rubbers are designed for use with
speed glue. Some rubbers when reglued will
provide better results than others. Therefore,
we have given each of our rubbers a ‘high’,
‘med’, ‘low’ or ‘not
recommended” rating based on how well
they will react to speed glue. Generally,
the softer the sponge the higher the "reglue
effect" will be. This effect will dissipate
over time. Some glues will last only a few
hours while others will last a number of days,
depending on which type you use. The rubbers
will remain attached to the blade surface
even after the glue effect is gone.
WHAT IS SPONGE DENSITY:In the highly technical world of table tennis equipment, Butterfly
strives to give our customers as much information as possible to help
each person choose the equipment that best meets their needs. To that
end, we are now publishing a list of Sponge Density Ratings. In
general, players who swing harder prefer the harder sponges. The denser
sponges have more stored energy but also require more racket speed to
compress the sponge and release this energy. The all-round player or
players with shorter strokes will prefer sponges with medium or softer
sponges.
SPONGE THICKNESS: Many rubbers offer multiple sponge thicknesses. The sponge layer, the area between the top sheet and the wood, acts as a trampoline. Thinner sponge will be less “springy” and have a hard feel, as the ball will generally sink to the wood surface, producing less spin and speed. Thicker sponge will have a soft feel and will be faster and provide more spin as the ball will sink deep into the sponge layer catapulting it outward with tremendous velocity and increased spin.
No Sponge(OX)-1.3mm: For defensive style players who emphasize control.
1.5-1.7mm For all-round players who desire good control with medium speed.
1.9mm-Max For offensive players who attack with high speed and spin.
