Polyester Wire: LONG LIFETIME With UV stabilizer, the polyester wire has very long lifetime for outdoor and indoor use. THERMIC STABILITY Between -40---+70 temperature, the polyester wire keep very good stability of mechanical performance and geometry measures. HIGH TENSION STRENGTH Compared with nylon wire, it has very low stretching percentage. So it can be quickly tensioned. Moreover, once it is tensioned, it can keep the status of tension and does not need to be tensioned again. So polyester wire is different from wires with low tension strength like nylon, you have to tension nylon again and again. PERMANENT SMOOTHNESS The polyester wire never absorb humidity. So after years of usage, the surface of it keeps smooth and it never tears. PRACTICAL USAGE The polyester wire can be tied and untied many times. So when used on the shading screen system of greenhouse, you dont need any additional plastic wire to tie.
