POLYPROPYLENE

A crystalline, thermoplastic resin made by the polymerization of propylene. The product is hard and tough and flexible, resists moisture, oils and solvents, and withstands temperatures up to 130°C. It is used to make molded articles, fibers, films, ropes and toys. In the medical field it is generally utilized for test tubes and containers moulding.

POLYSTYRENE

Water-white, tough synthetic resin made by polymerization of styrene; soluble in aromatic and chlorinated hydrocarbon solvents. It is used for injection moulding, extrusion, fabric lamination, and generally moulding of plastic objects. In the medical field it is utilized in the moulding of test tubes and containers when an optimal transparency is requested.

PMMA

Thermoplastic polymer derived from methyl methacrylate. Transparent solid material with excellent optical qualities and water resistance; used for optical instruments and surgical appliances. In the medical field it is used particularly for serum separating test tubes moulding as it is the polymer most similar to the glass.

POLYETHYLENE

Thermoplastic material composed of polymers of ethylene; the resin is synthesized by polymerization of ethylene at elevated temperatures and pressures in the presence of catalysts. In the medical field it is utilized for the production of stoppers and Pasteur pipettes.

PET

Transparent resin with very good mechanical resistence and excellent barrier effect. Particularly suitable for the production of tubes with pre-determined vacuum.
