Hydrolysis-resistant PBT solves the problem of water decomposition and temperature resistance in the production of automotive electronic components
With the maturity of new energy vehicles and autonomous driving technology, the market demand for automotive electronic materials is increasing. For example, the traditional automotive electronic materials basically have no flame retardant requirements, while the electronic materials used in new energy vehicles require flame retardant level. This presents a problem to vehicle manufacturers, automotive electronic […]
Application of anti-hydrolysis agent in PET polyester monofilament for paper making clothing industry
What is polyester monofilament? Polyester monofilament is made from PET chips. The chips are spun by melt method, then cooled and shaped in a bath, and finally drawn and thermoformed to get monofilament. Polyester monofilament is characterized by high strength, good toughness, dimensional stability, high temperature and low-temperature resistance, and chemical stability to acids and […]
Modification of PET Engineering Plastics
In order to compete with other general-purpose resins and expand their application areas, manufacturers are constantly modifying PET engineering plastics. The modification focuses on the following areas: a) Improvement of formability. PET engineering plastics may crystallize rapidly at lower temperatures by selecting various nucleating agents and crystallization promoters to speed up the crystallization of PET […]
How to improve the hydrolysis resistance and service life of dryer fabrics in paper machine clothing？
PET monofilaments have a series of advantages such as good impact resistance, wear-resistance and fatigue resistance, but PET is prone to hydrolysis aging and failure under humid and especially hot and humid conditions. The paper machine dryer screen usually works under an environment of 100℃ containing water and gas. Because PET material is not resistant to […]
