pH-limit list - Resistance to inorganic acids, alkalis & saltsUsing the pH-limit list can be determined the chemical resistance of plastics to inorganic acids, alkalis & salts. Intable 11 are listed as example, the pH values of some typical substances. Whereas ,in table 12 are listed the pHlimit values of the ZEDEX ® materials. When a chemical’s pH-value is between the limit value of two materials,the material with the higher limit value is the resistant one to this chemical.SubstancespHvalueKindMaterialpH-valuelowerlimitpH-valueupperlimitLead-acid battery < 0Gastric acid 1,0 - 1,5Lemon juice 2,4Cola 2,0 - 3,0Vinegar 2,5Morello cherry juice 2,7Orange or apple juice 3,5Wine 4,0Sour milk 4,5Beer 4,5 - 5,0Acid rain < 5,0Coffee 5,0Tea 5,5Rain 5,6Mineral water 6,0Milk 6,5Water (depending on hardness) 6,0 - 8,5Human saliva 6,5 - 7,4Blood 7,4Seawater 7,5 - 8,4Pancreatic juice 8,3Soap 9,0 - 10,0Household ammonia 11,5Bleach 12,5Concrete 12,6Household lye 13,5 - 14,0acidacid to alkalialkaliZX-100K 1 9ZX-100EL55 1 9ZX100EL63 1 9ZX-100MT 1 9ZX-324 1 14ZX-324V1T 1 10ZX-324V2T 1 14ZX-324V11T 1 14ZX-324VMT 1 14ZX-410 1 9ZX-410V7T 1 9ZX-530 1 14ZX-530CD3 1 14ZX-530EL3 1 14ZX-530KF15 1 14ZX-550 1 14ZX-550PV 1 14ZX750V5T 1 9ZX-750V5KF 1 9Table 12: pH-limit values of the ZEDEX ® materialTable 11: typical pH values122 ZEDEX ® basic types ZEDEX ® families Post heattreatmentMachiningShippingoverviewSterilizationChemicalresistance
Legal informationAll the tests are been made with a standard conditioning atmosphere of 23°C (at the moment no other temperatureis available). The specified values are established from average values of several tests and they correspondto our today’s knowledge. They are only to be used as information about our products and as help for the materialselection. With these values, we do not ensure specific properties, or the suitability for certain application, thereforewe do not assume any legal responsibility for an improper usage. The used test pieces have been machinedfrom extruded semi-finished material. Since the plastics´ properties depend on the manufacturing process (extrusion,injection moulding), on the dimensions of the semi finished material and on the degree of crystallinity, theactual properties of a specific product may slightly deviate from the tested ones. For information about divergentproperties do not hesitate to contact us. On request we advise you regarding the most appropriate componentdesign and the definition of material specifications more suitable to your application data. Notwithstanding, thecustomer bears all the responsibility for the thorough examination of suitability, efficiency, efficacy and safety ofthe chosen products in pharmaceutical applications, medical devices or other end uses.ZEDEX ® basic types ZEDEX ® families Post heattreatmentMachiningShippingoverviewSterilizationChemicalresistance123
