Akron 4X Silicone™ Mold Rubbers

EXTREMELY HIGH TEAR RESISTANCE

Notice the shine?
Wait till you see the wax!


4X Gold Introduced in 1994, was the first true high strength silicone developed for jewelers. Emulated by many in the ensuing years, 4X Gold chemistry still provides the most desirable combination of properties available today.

4X Blue followed shortly, providing a much more firm mold for large patterns as well as all powder separation applications.

4X Quick-Cure Is the very first rapid curing silicone. Introduced in 2001, it is a medium hardness rubber. Cured in half the traditional time at 7 minutes per 1/4 inch of thickness, it also provides very high tear strength and nice flexibility.

LSLT-160, introduced in 2003 is the very first high speed cure capable mold rubber. A 1/2" mold cures in only ten minutes at 250ºF. Also designed for curing at 160ºF, it neatly copies carved waxes as well as RP resin patterns. LSLT-160 is known as the "metal mold rubber" for it's ability to provide extremely crisp detail usually seen only in metal molds.

4X ZeroShrink™ is the most recent arrival from our lab. This is the only zero shrink heat cure mold rubber of any kind available today. This rubber provides results normally only seen from a metal mold.
