SK78 Prisma-Siri® S-12

SK78 Prisma-Siri® S-12 is a unique 12 strand High Modulus/High Performance rope made of SK78 fibers. The Prisma® Shield technology enhances the SK78 fiber’s superb characteristics, resulting in a really strong and durable rope, ideal for the most demanding applications in the shipping industry.

SK78 Prisma-Siri® S-12 ropes are 8 times stronger than steel ropes and 3 times stronger than polyester (on a weight by weight comparison).

APPLICATIONS: MOORING / TOW LINES / STS OPERATIONS (to be used with synthetic tails) / ANCHORING / OFFSHORE / AQUACULTURE / FISHING / YACHTING

The special Prisma® Shield technology and the elaborate in-house Linear Structural Preformation (LSP) process upgrade the SK78 fibers to a level of superior performance. The application of Prisma® coating is performed on the fiber level and protects the SK78 fibers from abrasion and UV radiation. In the end, the whole process guarantees a top-quality rope with extra high strength efficiency and excellent abrasion resistance.

When compared to wire ropes, SK78 Prisma-Siri® S-12 ropes are stronger (for the same weight), lighter (making it easy and fast to handle), safer to use and cost-saving (minimum maintenance needs, no greases, faster operating times).
