Epoxy Granite - Advantages and Disadvantages

Advantages and Disadvantages

Advantages include:

• Vibration damping.
• Flexibility: custom linear ways, hydraulic fluid tanks, threaded inserts, cutting fluid, and conduit piping can all be integrated into the polymer base.
• Inclusion of inserts etc. allows greatly reduced machining of the finished casting.
• Assembly time is reduced by incorporating multiple components into one casting.
• Does not require a uniform wall thickness, allowing for greater design flexibility of your base.
• Chemical resistance to most common solvents, acids, alkalis, and cutting fluids.
• Does not require painting.
• Composite has a density approximately the same as aluminum (but pieces are thicker to achieve equivalent strength).
• The composite polymer concrete casting process uses much less energy than metallic castings. Polymer cast resins use very little energy to produce, and the casting process is done at room temperature.

Epoxy granite material has an internal damping factor up to ten times better than cast iron, up to three times better than natural granite, and up to thirty times better than steel fabricated structure. It is unaffected by coolants, has excellent long-term stability, improved thermal stability, high torsional and dynamic stiffness, excellent noise absorption, and negligible internal stresses.

Disadvantages include low strength in thin sections (less than 1 in (25 mm)), low tensile strength, and low shock resistance.
