Lupolen 4552D BLACK
Bu ürün hakkında
Lupolen 4552D black is a UV and thermal stabilised high-density polyethylene with a multimodal molecular weight distribution designed for extrusion. Lupolen 4552D black is produced with the advanced Hostalen technology which provides the material with excellent mechanical and physical properties. The excellent dispersion of the fine particle sized carbon black ensures the material has excellent weathering resistance.
Lupolen 4552D black fulfils the requirements of DIN 30670, NFA 49710, CAN, CSA-Z245.21-M98 and prEN 10285 when used in combination with the maleic-anhydrided grafted adhesives Lucalen. G3710E P and a compatible fusion-bonded epoxy powder.
Lupolen 4552D black is recommended as the topcoat layer in 3LPE pipe coating applications and is suitable for severe laying conditions even at elevated temperatures. Lupolen 4552D black can be used up to 85°C service temperature of the pipeline when used in combination with the maleic-anhydride grafted adhesives Lucalen G3710E or Lucalen G3710E P and a compatible fusion-bonded epoxy powder.
This grade is available in black, in pellet form.
