Hoses used for transfer of PET resin at drying temperatures of 80°C to 100°C collapsed due to the heat, preventing the stable supply of raw materials and leading to frequent mold defects. As well, static electricity was generated from the powder transfer, adhering the raw materials to the hose interior so that the materials mixed during changeover and contaminated the product with foreign matter, which also required countermeasures.

Heat leads to hose collapse, preventing stable supply of raw materials
Replacement with the TOYOTOP-E-100°C Hose, with heat-resistant and antistatic functions, prevented hose collapse and enabled a stable supply of raw materials. Without the influence of static electricity, the adherence of raw material was no longer a problem, reducing product defects free of concern about foreign matter contaminating the product.
