Industrial thread should have special characteristics like strength, high modules, resistant against heat shocks, strokes, chemicals and strain.
There are many applications which industrial threads can be used for such as, tyre cords, seatbelt, strong cords, conveyor belts, airbags, fishing nets, sail and medical stitches.
The processing requirements for a PET-SSP plant for tyre cord are different to those for a bottle grade plant: first, the raw material is typically a homopolyester with a melting point of 260°c or higher, secondly the final viscosity of 1.0 to 1.2 is much higher, and thirdly the plant throughputs, typically between 30 and 90 t/d , are much smaller.
