Polyphenylene sulfide (PPS), is a special engineering plastic with excellent comprehensive properties. PPS is characterized by excellent high temperature resistance, corrosion resistance, radiation resistance, flame resistance, balanced physical and mechanical properties, and excellent dimensional stability which can be used as structural polymer materials and as special engineering plastics after modification.
Besides, PPS can
also be made into various functional films, coatings and composite materials, and
has been successfully applied in electronics, environmental protection,
petrochemical, aerospace, and automotive industries.
downstream industries are developing rapidly in the recent years, the global
demand for PPS is also rising continuously from 2011 to 2017 with the average
annual growth rate of 10.26%. In 2017, the global PPS demand is about 115,000
MT while the PPS output is about 117,000 MT.
The global PPS
industry is highly concentrated. The world's leading PPS suppliers are mainly
from the United States, Japan and China, among which Japan is the largest
producer of PPS, accounting for about 45% of the world's total production
capacity. The top five PPS manufacturers are Toray, DIC, Solway, NHU and
Fortron, accounting for over 50% of global PPS production capacity.

China is also the
largest PPS consumer in Asia with the market demand of PPS rising from 13,000
MT in 2010 to 47,000 MT in 2017. As the electronic, environmental protection
and automotive industries develop rapidly in China, the PPS production and
demand have become increasingly tight and there will be a severe competition
between the foreign and domestic PPS suppliers.
However, as a special
engineering plastics, PPS has high technical barriers with high price. The
modified PPS yield is much lower than other engineering plastics and general
plastics. In addition, there is still a big gap between the quality of domestic
and imported modified PPS due to the unstable formula of domestic modified PPS,
and the unstable quality of domestic resin products.
