Used in hundreds of industrial and art-related applications, many of our PMC™ rubbers are easy to use and exhibit excellent wear resistance. They cure with negligible shrinkage. They are economical, reproduce exceptional detail and are perfectly suited for production casting of concrete, gypsum and wax. Some PMC™ rubbers are suitable for mechanical parts (gaskets, wheels, pulleys) as well as ball mill liners and vibration/shock pads.
These rubbers will meet the stringent demands of production casting of wax, plasters, concrete, resins and epoxies. The dry version does not exude an oil and can be used for casting waxes, resins, gypsum plasters and other materials. The wet version contains a built-in release agent to aid in demolding hard plasters and concrete.
Using optional ‘Part D', you can thicken PMC™-724 to a paste-like consistency for vertical surface brush-on applications or for getting into those hard-to-reach undercuts. If you like to work with a more flexible rubber, optional ‘Part C' is available to soften PMC™-724 all the way down to a Shore A6.
Used for years by mold making professionals to cast plaster, concrete, resins, etc. It is excellent for making molds that are strong, durable and dimensionally stable.
Developed to make molds for casting gypsum plasters including making plaster block molds, reproducing ornamental plaster, and also for pre-cast concrete molds, casting waxes, or rigid polyurethanes and epoxies.
These hard rubbers offer superior tear and tensile strength, impact and abrasion resistance. Suitable for making concrete stamping pads, mold liners and molds for casting concrete. Also good for making ball mill liners, industrial rollers and belts, rubber mechanical parts.
