TORLON BALLS

TORLON 4203 L

A polymer not subjected to deformation and highly resistant to loads and high temperatures. It offers considerable advantages compared to metals or other kinds of plastics which are unable to withstand high temperatures or heavy loads. Torlon is a material lighter than others, it is not subject to corrosion, and it does not require lubrication. It is compact and tough, and it can withstand strong compression, distortion and impacts. It is resistant to abrasion and hydraulic fluids, hydrocarbons and combustible gases..

Because of these characteristics, Torlon is the ideal material for many industrial applications, such as pneumatic and hydraulic valves, nautical accessories, bearings for linear movements, and control valves. Torlon, due to its low weight and inertia, ensures faster response to pressure changes compared to metals and better sea at low pressures. As they are self-lubricating, Torlon balls are not subjected to attack by impurities or fats which could impair performance.

Torlon 4203 L contains 3% of pigment and 0,5% of additive. Torlon 4301 has been designed for high friction and abrasion conditions and contains 12% of graphite powder and 3% of additive.

Breaking point test with parallel plates (also known as the compression strength critical point test): This test determines the maximum load at which a critical breaking or total fracture point can be observed on the sample being examinated. A loads is applied to the upper plate of a device that carries out the test at a rate of 1.3 mm/min until the critical point is reached.

The maximun load and deflection under stress values are obtained from a reading of the data recorded by tha machine during the test and permanent deformation or set in measured under load. The values obtained represent a mean value for a sample of 10 items tested.

Compression tests determine the capacity of the ball to bear load of 150 kg for 5 seconds using a materials testing machine. The load is applied to the upper plate at a rate of 1,33 mm/min. Permanent deformation (set) is measured as the change of diameter recorded immediately after the end of the test. Deflection under load represents the total change in the diameter with the load applied and is measured by a recorder applied to the machine. The data obtained are a mean value for 10 samples.

Diameters produced: from mm 3,175 to mm 25,40
