PET Broom bristle filament
The thermal deformation temperature and long-term use temperature are the highest in thermoplastic general engineering plastics;
Because of the high heat resistance, the enhanced PET is impregnated for 10s in the solder bath at 250 ° C, almost without deformation or discoloration, which is especially suitable for the preparation of electronic and electrical parts for solder welding;
The bending strength is 200MPa, the elastic modulus is 4000MPa, the creep resistance and fatigue are also very good, the surface hardness is high, and the mechanical properties are similar to thermosetting plastics;
Because the price of ethylene glycol used in the production of PET is almost half cheaper than that of butanediol used in the production of PBT, PET resin and reinforced PET are the lowest in engineering plastics and have a high cost performance.
