PROPERTIES OF PLASTIC MATERIALS

1 221 PROPERTIES OF PLASTIC MATERIALSRECOMMENDEDAPPLICATION: For dimensionally stable andtemperature-resistant parts. stable, heat-resistant,self-extinguishing parts, mainly whenexchanged with metal. Componentparts and cases for entertainmentindustry and data processing suited for technical application,especially for machine elements withcomplicated for cases housinginstruments and general indoor andoutdoor application . Not recommendedfor use with strong alkalis or for directexposure to suited for indoor use withmoderate corrosive conditions.

2 Limitedoutdoor suitablility. Special materialscomply with ball-thrust hardness testaccording to VDE 700 at 125 .Cases and operating elements of allkinds. Indoor use, also suitable for lowtemperature. Limited outdoorapplication. Suitable for cases and operating elements withworking temperature of less than 65 .Suitable for indoor use. Exposure toUV-light should be and front panels for infraredtransmitters and receivers as well astransparent OFMATERIAL: Reinforced PolyesterExcellent temperature stabilitycombined with a high degree of impactstrength.

3 On the whole, a high stabilityagainst chemicals. Good long-timerupture good mechanical, thermaland electrical PROPERTIES . Good ageingstability and weathering stability against with high temperaturestability, extremely solid and sliding PROPERTIES and highcapacity of resistance to wear. Contactwith humidity may result in a change with high temperaturestability with excellent resistance to allkinds of temperature. On the whole,good resistance against chemicals BlendGood stability in case of hightemperature combined with enormousimpact strength as well as toughness atsubzero temperature.

4 On the whole,good resistance against chemicals. UV-light may have a negative resistance against mediumtemperature combined with goodimpact strength (only certain types)and antistatic adjustment. On thewhole, good resistance againstchemicals. UV-light may have a brittle and resistant to fairlylow temperature. SB-types are impactresistant and less sensitive to tearingunder pressure. Glossy surface. Metal-cutting is (plexiglass )Good mechanical PROPERTIES , slightlybrittle. Superior from optical point ofview.

6 None of the testsample burns longer than 10 seconds. None of the testsample emits 94 V-1:The test samples areextinguished within 25 seconds average time(mean of 10 succesivetests). None of the testsample burns longer than 30 seconds. None of the testsample emits 94 V-2:Same Test as UL 94 V 1, butthe test samples emitsburning particles during test samples mentionedabove are extinguished in allcases. If the test sampleskeeps burning after 30 seconds, a horizontal testcan be carried out to reachthe classification UL 94 to technical modification without notice.
