Material Notes:
POLIPOM® is a plastic which is manufactured by the polymerization of formaldehyde. Its high proportional crystallized structure of the oxygen and methyl groups inside, provides it high proportional hardness and strength even without any addition of reinforced structure material. It is resistant to alkalis and hot water. It is resistant to organic solvents which are commonly used, to petroleum products and to many of the mineral oils.PROPERTIES OF POLIPOM®:Dimensional StabilityHigh Resistance To Loads and StrokesExcellent Resistance To CorrosionHigh Mechanical Strength and Non-TwistingHigh ElasticityBearing Property at Environments Without OilHigh Electrical Insulation PropertyLow Absorption Resistance To Heat(-50°C - +110°C / short period 150°C)GENERAL USAGE AREAS OF POLIPOM®: As per its above mentioned technical properties, POLIPOM® is most commonly used in the production of machine molding parts at all sectors; gears, bearings of rolling mills and bearings exposed to extreme loads, conveyor systems, pins, unlimited screws, pistons, pivots and areas like these.
