Anti-UV Plastics Comparison Chart of F1 F2

Plastic Injection Materials: Weather-Resistant Level Anti-UV PlasticsF1 F2

F1 indicates the level suitable for outdoor uses and meets weather resistance/durability specifications of UL746C.

F2 indicates the level suitable for outdoor uses and meets weather resistance/durability specifications of UL746C.

F1 indicates both “UV exposure test” and “water exposure test and immersion test”.

F2 indicates suitable for one of the tests.

UV exposure test Exposure 72 hours under two closed carbon arc lamps, or 1000 hours under xenen arc lamps. Remaining unchanged under the conditions is qualified.
  After test, property of tensile strength, bending strength, tensile impact strength, izod impact strength, and charpy impact strength remains over 70%.
   
Water exposure test and immersion test Weather resistance level remains unchanged after7 days of hot water treatment under 70 degrees C
  After test, property of tensile strength, bending strength, tensile impact strength, izod impact strength, and charpy impact strength remains over 50%.
