PROPERTIES OF PLASTIC MATERIALS The plastic and packaging CHOICE OF RECOMMENDED material used by OKW are on MATERIAL: APPLICATION: the whole harmless and, apart from some exceptions, Reinforced Polyester can easily be recycled and Excellent temperature stability For dimensionally stable and combined with a high degree of impact temperature-resistant parts. Outdoor reutilized. strength. On the whole, a high stability application. against chemicals.

Component as cases and technical parts UL subject 94 High stability against chemicals. parts and cases for entertainment are concerned. industry and data processing units. The plastic materials are classified as follows: Polyamide Thermoplast with high temperature Ideally suited for technical application, UL 94 V-0: stability, extremely solid and tenacious. especially for machine elements with The test samples are Good sliding properties and high complicated geometry. capacity of resistance to wear. Contact extinguished within with humidity may result in a change of 5 seconds average time properties. (mean of 10 succesive tests).

Not recommended sample emits burning good resistance against chemicals and for use with strong alkalis or for direct particles. UV-light. exposure to sunlight. UL 94 V-1: PC-ABS Blend The test samples are Good stability in case of high Ideally suited for indoor use with extinguished within temperature combined with enormous moderate corrosive conditions. Limited impact strength as well as toughness at outdoor suitablility. Special materials 25 seconds average time subzero temperature. On the whole, comply with ball-thrust hardness test (mean of 10 succesive good resistance against chemicals. according to VDE 700 at 125. tests).
