Teorema srl was founded in 1984 and works both on Italian and foreign markets with 800 customers and an on-site laboratory for testing compounds and the chemical/physical analysis of manufactured products.


It manufactures the following articles using injection and compression machines: technical rubber items designed by customers, lip seals, gas membranes, fabric-reinforced seals, silent blocks, gaskets for fittings, bearings, sealing rings for pneumatic cylinders, O-rings, technical articles for electro-mechanics, and die cut and lathe cut gaskets.


Its compounds are certified for a variety of uses and industries. It uses all the polymers available today:

NBR Nitrile Rubber

ACM Polyacrylate

VMQ Silicone

VITON® FKM Fluoroelastomer

HNBR Hydrogenated Nitrile Rubber

NR Natural Rubber
