BEAVER FIBRE ROPE PRODUCT INFORMATION
SYNTHETIC (MAN MADE) FIBRE ROPE For any given diameter, ropes made from synthetic materials are generally far stronger and much cheaper than those made from natural fibers. Because of low water absorption the breaking strain of synthetic rope remains constant even when wet; when it breaks however, it does so without warning. Synthetic rope is resistant to rot, has a longer life, and can be colored for ease of recognition. Rope ends can be heat sealed to prevent unlaying of the strands. The relatively low melting point of most man-made fibers means that it is important to avoid friction or synthetic ropes binding against each other - knots can actually fuse together when put under load.
NYLON › Nylon is the generic description for synthetic polymers › High breaking strength › Light weight per unit of strength › Excellent elasticity and tensile recovery › Superior absorption of impact and shock loads › Excellent flexibility and abrasion resistance, which is ideal for pulley systems or winches › High resistance to creep under sustained loads › Is not damaged by oil or most chemicals › Does not become progressively softer with a rise in temperature › Excellent resistance to rotting › Good sunlight and weather resistance › High melting point › Absorb moisture and lose approximately 10% of their strength when wet
› Nylon is unsuitable for lifting as the slings would stretch and cause the loads to bounce › Are sensitive to phenols, strong acids, concentrated formic acid, sunlight › Has resistance to acetones, organic solvent, mineral and organic acids
MECHANICAL PROPERTIES: › Specific gravity: 1.14 g/cm3 (Doesn’t float on water) › Melting point: 215-260°C
› Resistance to short term Heat: 130°C › Tensile Strength of Nylon: 100 kg/mm2 › Elongation at break points: 18-24% › Ultra Violet (UV) resistance: Good › Resistance to Alkalis: Good at low concentration › Resistance to Acids: Predominantly good
