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 homogenous structural composition, - 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.
