Borealis PP4821
PP(聚丙烯)
博禄/北欧化工(Borealis AG/Borouge)
产品描述
PP4821 is a thermoplastic, non-halogen containing, insulation compound based on a polypropylene copolymer.
The composition of PP4821 is based on the elements Carbon and Hydrogen. Compounds based on these elements will therefore be the only significant constituents of the fumes due to the combustion of this product. Other elements may be present in concentrations less than 0.1%
Applications
PP4821 is designed for: 70°C rated insulation for building wires (installation cables), flexible cords, power cables It can be used in areas sensitive to smoke or corrosive and toxic combustion products. PP4821 is stabilised for use in contact with copper.
Specifications
PP4821 meets the applicable requirements as below when processed using sound extrusion practice and testing procedure: DIN VDE 0250 Pt 215-NHMH
Special features
PP4821 consists of specially selected components to offer: Low smoke and reduced toxic or corrosive gas emissions processing properties Superb system ageing compatibility Low water permeability Processability on most PVC/PE extrusion equipment No need for pre-drying normally
