POLIPA®- PA6 (POLYAMIDE) It is produced by poly condensation of e-aminoacid and by the help of d-carbon acid and d-amine poly condensation. Its characteristics depend upon the numbers of the main structural key carbon atoms, which polyamide contains. Polyamide 66 contains six carbon atoms of d-amine (Hexamethylene d-amine) and six carbon atoms of d-carbonic acid (Adipinacid). This situation is valid also for polyamide 610, which is produced from hexamethyelene d-amine and sabazine acid. Its composition has significant effect on polyamide's properties. Especially, water absorption is mostly effected. As much as CH2-group exhists at each CONH-group, water absorption is that much low and dimension accuracy is that much good. (1% humidity absorption equals to 0,3% length elongation.) Parts which are requested to have dimension accuracy at humid atmosphere, are full only with 1.5% water and preferably are made of polyamide 11.(For comparison this value is 10% for PA6.) Polyamide is preferred as construction material at the conditions where exact measurements are required and which are mechanically loaded like gear wheel, rod, bolt. Its mechanical properties are significantly dependent on its humidity quantity and degree of crystalization. It can be used also at higher temperatures because of its crystal structure and high melting point. But, when the temperature is higher than 100°C and when there is oxygen at the environment, damage occurs with oxidation. For this reason, for usage at atmosphere only stabilized ones are chosen. As a result, POLIPA, is a hard plastic due to its high molecular weight and its structure of crosswise bonds. It is resistant to twisting and corrosion. It has the property of working for a long time under load. But, due to its water absorption (9-10%), it is not recommended at humid environments.
