3 Strand Rope - Is the most economical rope available on the market. It consists of many tiny fibres spun into yarns, and then formed into strands. 3 Strand ropes are flexible, easily spliced and knotted. Fibres can include Manila, Sisal, Polypropylene, Danline (Copolymer), Nylon and come in a Hard, Medium(standard) and Soft Lay.

8 Strand Rope - Is commonly used on or in conjunction with commercial vessels in marine applications. Plaited 8 strand ropes have four right hand laid strands and four left hand laid strands which produces a torque balanced rope. 8 Strand Ropes are easily spliced and has good abrasion resistance. Fibres can include Polypropylene, Nylon, Dual Fibre Blend and Polyester.

12 Strand Rope - Is produced to provide significant improvement in performance, life expectancy and strength. Plaited 12 strand ropes have six right hand laid strands and six left hand laid strands which produces a torque balanced rope. 12 Strand Ropes are easily spliced and offer greater abrasion resistance combined with higher strengths. Fibres can include Spectra, Polyester, Nylon and Dual Fibre Blend.

Double Braid Rope - Is a common marine rope which is designed for great strength to weight ratio. Double Braid ropes have a braided core encased in a braided jacket cover and is designed to bear equal load on the core and cover. These ropes offer high strength and very good abrasion resistance. Fibres can include Nylon, Polyester, Spectra Core, and Dual Fibre Blend. COMMON ROPE CONSTRUCTIONS

Other Constructions - With constant demand for higher strength and longer life, rope constructions are continually being upgraded. For mooring applications 4 strand, 6 strand, 7 strand and 24 strand ropes are being manufactured from Aramid fibres to produce high strength and easily spliced rope.

Diamond Braid, Single Braid and Sash Cord are used to produce smaller cords. Sash cords are very economical in price. Diamond and Single Braid are produced for durability and strength at an economical price.

A rope is a linear collection of natural or artificial plies, yarns or strands which are twisted or braided together in order to combine them into a larger and stronger form, but is not a cable or wire. Ropes have tensile strength and so can be used for dragging and lifting, but are far too flexible to provide compressive strength. As a result, they cannot be used for pushing or similar compressive applications. Rope is thicker and stronger than similarly constructed cord, line, string, and twine.

Rope may be constructed of any long, stringy, fibrous material, but generally is constructed of certain natural or synthetic fibres. Synthetic fibre ropes are significantly stronger than their natural fibre counterparts, but also possess certain disadvantages, including slipperiness.

Common natural fibres for rope are manila hemp, hemp, linen, cotton, coir, jute, straw, and sisal. Synthetic fibres in use for rope-making include polypropylene, nylon, polyesters (e.g. PET, LCP, HDPE, Vectran), polyethylene (e.g. Dyneema and Spectra), Aramids (e.g. Twaron, Technora and Kevlar) and acrylics (e.g. Dralon). Some ropes are constructed of mixtures of several fibres or use co-polymer fibres. Rope can also be made out of metal. Ropes have been constructed of other fibrous materials such as silk, wool, and hair, but such ropes are not generally available. Rayon is a regenerated fibre used to make decorative rope.

The twist of the strands in a twisted or braided rope serves not only to keep a rope together, but enables the rope to more evenly distribute tension among the individual strands. Without any twist in the rope, the shortest strand(s) would always be supporting a much higher proportion of the total load.

Propylene was first polymerized to a crystalline isotactic polymer by Giulio Natta as well as by the German chemist Karl Rehn in March 1954. This pioneering discovery led to large-scale commercial production of isotactic polypropylene by the Italian firm Montecatini from 1957 onwards. Syndiotactic polypropylene was also first synthesized by Natta and his coworkers.

Polypropylene (PP), also known as polypropene, is a thermoplastic polymer used in a wide variety of applications including packaging and labeling, textiles (e.g., ropes, thermal underwear and carpets), stationery, plastic parts and reusable containers of various types, laboratory equipment, loudspeakers, automotive components, and polymer banknotes. An addition polymer made from the monomer propylene, it is rugged and unusually resistant to many chemical solvents, bases and acids.

These ropes are tested for linear density, strength and elongation for every lot. They are also specially packed for fisheries use and they float on water.

Various industrial applications like Fisheries, Marine, Agriculture, Transportation, Safety, Construction, Sugar Industry, Telecommunication Industries, Cargo Nets, Heavy lifting, safety line, anchor, etc.

Most commercial polypropylene is isotactic and has an intermediate level of crystallinity between that of low-density polyethylene (LDPE) and high-density polyethylene (HDPE). Polypropylene is normally tough and flexible, especially when copolymerized with ethylene. This allows polypropylene to be used as an engineering plastic, competing with materials such as ABS. Polypropylene is reasonably economical, and can be made translucent when uncolored but is not as readily made transparent as polystyrene, acrylic, or certain other plastics. It is often opaque or colored using pigments. Polypropylene has good resistance to fatigue.

8 Strand Polypropylene Rope are primarily used for mooring, towing/typing or similar application. These ropes are made on the latest & modern machinery using latest technologies hence posses excellent standards & properties.

Traditionally, three manufacturing process are the most representative ways to produce polypropylene.

Hydrocarbon slurry or suspension: Uses a liquid inert hydrocarbon diluent in the reactor to facilitate transfer of propylene to the catalyst, the removal of heat from the system, the deactivation/removal of the catalyst as well as dissolving the atactic polymer. The range of grades that could be produced was very limited. (The technology has fallen into disuse).

Bulk (or bulk slurry): Uses liquid propylene instead of liquid inert hydrocarbon diluent. The polymer does not dissolve into a diluent, but rather rides on the liquid propylene. The formed polymer is withdrawn and any unreacted monomer is flashed off.

Gas phase: Uses gaseous propylene in contact with the solid catalyst, resulting in a fluidized-bed medium.
