thermal stability and long-term continuous use of short-term，

thermal stability were better than all of the engineering plastics at present. Specially modified varieties, thermal deformation temperature can reach more than 350℃.Processing performance is good, the melt viscosity of PPS resin is low, liquidity is good, easy to contact with the glass fiber wetting, so the filling packing is easy, with its preparation of glass fiber or inorganic filler reinforced injection grade aggregate, with very high。
