BEAVER FIBRE ROPE PRODUCT INFORMATION
POLYPROPYLENE › Light weight with ability of floating on water › Doesn’t lose strength in wet environments › Immune to attack by rot and mildew › Highly resistant to attack by acids and alkalis › Often sleeved with a braided material for softer handling
› Affected by sunlight deterioration, more so than any other synthetic › Not as strong as nylon or polyester, but 2-3 times stronger than manila › Softens progressively with a rise in temperature › Begins to weaken and melt at 150°c › Excellent dielectric ability and does not conduct an electric current and acts as an insulator › Lacks stretch memory. When stretched, it will not return to its normal size › Sensitive to bleaching agents (sodium hypochlorite), cleaning agents (trichloroethylene) › Resistance to most alkalis and acids, solvent and oxidizing agents
MECHANICAL PROPERTIES: › Specific gravity: 0.91 g/cm3 (Float on water) › Melting point: 150-175°C › Resistance to short term Heat: 80°C › Tensile Strength of polypropylene: Approx 60 kg/mm2 › Elongation at break points: 13-17 %
› Ultra Violet (UV) resistance: Fair › Resistance to Alkalis: Excellent › Resistance to Acids: Excellent
