Juma Black Handle Block

JUMA is a high grade, modern raw material for the manufacture of components and works of art. JUMA consists of a mixture of different mineral base materials compounded with a resin component.

The essential characteristics of JUMA are:

• excellent mechanical machinability i.e. for drilling, milling, grinding and polishing,
• minimum breakage risk due to high coefficient of elasticity and high elongation,
• high-quality surface due to high surface hardness and minimal abrasion losses,
• resistant to all conventional substances such as cleaning agents, oils, greases, weak / medium acids and bases,
• very low water absorption (hydrolysis resistant). - possibility of thermal moulding in boiling water,
• can be polished or lacquer coated to manufacture polished or matt surfaces,
• pleasant to the touch due to good thermal properties.

We recommend a final finish / polish using buffing wheels and rubbing compound
