PTT - new member of polyester material

PTT, namely polytrimethylene terephthalate, is attracting the attention of the industry as a new member of the polyester family. It is said that apart from being used as an excellent raw material for chemical fiber, PTT has a bright application prospect in engineering plastics, films, and containers. Therefore, it has become one of the most popular high-molecular materials currently developed in the world and is unique in PET.

The basic properties of PTT are higher tensile and recovery properties, lower modulus, lower melting point and glass transition temperature, easier crystallization, lower heat setting temperature than PET, and excellent dimensional stability. Weather resistance and transparency.

Experts say that PDO, one of the raw materials for PTT production, has been synthesized through bio-engineering technology, which provides a non-oil feedstock route for PTT production. At present, the direct esterification synthesis PTT widely used in foreign countries is characterized by short production process, low investment, no use of methanol, simplified recycling process, high production efficiency, and less pollution.

According to analysis, PTT will become a strong competitor for PET and nylon 66 in terms of engineering plastics.
