PPS

The molecular structure of PPS consists of benzene ring and sulfur atoms interarranged, the configuration is orderly, easy to form a high thermal stability of the crystal structure. At the same time, the molecular structure of PPS material has a highly stable chemical bond characteristics, the benzene ring structure makes PPS more rigid, and the sulfur ether bond (-S-) provides a certain degree of flexibility.

PPS itself has good heat resistance, flame retardant, chemical resistance, should be a promising material, but unmodified PPS has some unavoidable defects:

Difficult processing: 

This is the biggest pain point of all high temperature resistant materials -- high processing temperature, no matter the molding process or processing energy consumption, will face great challenges. In addition, PPS is still prone to thermal oxidation crosslinking in the melting process, resulting in reduced fluidity and further improve the processing difficulty;

Poor toughness:

PPS molecular chain is rigid, the maximum crystallinity is as high as 70%, the elongation is low and the welding strength is not so good. As a result, the impact resistance of unmodified PPS is poor, which limits the application scope.

High cost:

PPS raw materials and general engineering plastics compared, the price is about 1-2 times higher, and some modified materials compared with low cost performance;

Difficult coating:

PPS surface coating and coloring performance is not ideal. While this is not a major problem for now, it is a limiting factor.

PPS-LGF

Long glass fiber reinforced composites can solve your problems when other methods of reinforced plastics do not provide the performance you need or if you want to replace metal with plastic. Long glass fiber reinforced composites can cost-effectively reduce the cost of goods and effectively improve the mechanical properties of engineering polymers, and increase the durability by forming long fibers to form a long-fiber-reinforced internal skeleton network. Performance is preserved in a wide range of environments.
