The current PE line fibre comes from The SPECTRA and DYNEEMA lines. Swage uses the braided PE line with HMPE made by Nippon Dyneema Co., Ltd (Japan). The Thermal Plastic Gel (TPG) exterior adhesive technique prevents the coating from corroding, ensuring colour longevity. The line is rounded and braided 32 times per square inch effectively reducing friction and noise and increasing durability. The braiding improves tensile strength by 20% and strengthens the PR knot by 30%. This quality helps in further casting and a 10% drop off speed. The producer states that the line is able to withstand 800 hours of UV exposure and still maintain its quality. It is also able to withstand immersion in salt water , thinners, oil and chemical and industrial waste concentrations of up to 5%.
