USAGE
General recommendations based upon natural exposure tests. Specific applications have to be discussed.
1. PP tapesExposure: 45° South FloridaFailure criterion: KLy to 50% tensile strength retentionSamples: PP tapes of 50 micron containing UV uvr3KLy to 50% tensile strength retention
1 % UV UVR3380
2. PP thick sections
Exposure: 45° South FloridaFailure criterion: KLy to 50% retained impact strengthSamples: PP blockcopolymer parts of 2 mm thickness
KLy until 50% retained impact strength

Because of so many factors influencing the overall UV stability, it is important to know that our recommendations are based upon evaluations under IDEAL TESTING CONDITIONS, and can only be used as a guideline! FOOD APPROVALUV UVR3 can be used for food-packaging according to: EEC (90/128) not approvedDetailed information available upon request. PACKAGING AND STORAGEUV UVR3 is packed in 25 kg polyethylene bags on shrink-wrapped pallets. The storage time should not exceed 12 months for optimum performance.
