End of the year-end, high-strength polypropylene yarn purchase, transportation to choice!
Purchase high-strength fiber wire, why is our preferred shipped Changzhou Chemical Fiber Co., Ltd.? Because we produce high-strength polypropylene yarn has the following characteristics:
High-strength polypropylene multifilament yarn that is high-strength fiber, it belongs to the polypropylene fibers. Polypropylene fiber is neat and orderly arrangement of highly isotactic polypropylene polymer formed, and has a high degree of crystallinity. This structure makes high-strength polypropylene yarn has the following outstanding features in its performance:
(1) has a very high tensile strength, up 70.6 cN / tex (8g / d), which is almost double the ordinary polypropylene fiber.
(2) its density is the smallest synthetic 0.91, lighter than water.
(3) Thermal conductivity of 0.l ~ 0.3J / m · s · K, such a low value, it is a very good insulation properties.
(4) virtually no moisture absorption, resulting in difficult to dye, but may be liquid color masterbatches. Moisture absorption rate is zero so wet strength equal to dry strength, product strength will not fall in the water.
(5) has excellent chemical resistance, and a variety of fiber resistance, acid resistance, alkali resistance were compared, except not as good as PTFE fiber polypropylene fiber, but better than polyester, nylon, acrylic, polyvinyl alcohol, etc. .
(6) are not insects, bacteria corrosion, mildew resistant, outstanding resistance to microbial properties.
(7) Its melting point is only 176 ℃, so the heat resistance and thermal stability of poor performance, relatively speaking, this is the place polypropylene deficiencies. However, due to its thermoplastic properties make it in the 130C or less, after the temperature measured strength was increased instead.
(8) also wear the same wet and dry, resistant to grinding performance approaching nylon, wear-resistant curved slightly worse performance.
(9) Polypropylene poor light / easy to aging, but after adding a light stabilizer light performance fully meet the requirements.
In short, high-strength polypropylene filament belonging excellent mechanical properties of the fibers, it is an important industrial textile fiber material.
