Abstract
Polyether sulfone having a melt viscosity of 65 to 75 Pa·s at a resin temperature of 380° C. and shear velocity of 10000 s−1 is molded at a resin temperature of 350° C. or higher and a temperature of 370° C. or lower. The polyether sulfone being a blend product of polyether sulfones having different viscosities.
Claims2
A method for molding polyether sulfone, the polyether sulfone being a blend product of polyether sulfones having different viscosities,
- the method comprising the step of molding the blend product at a resin temperature of 350° C. or higher and 370° C. or lower, wherein the blend product has a melt viscosity of 65 Pa·s or more and 75 Pa·s or less at a resin temperature of 380° C. and shear velocity of 10000 s−1.
A molded article of polyether sulfone, the polyether sulfone being a blend product of polyether sulfones having different viscosities,
- the blend product being molded at a resin temperature of 350° C. or higher and 370° C. or lower,
- wherein
- the blend product has a melt viscosity of 65 Pa·s or more and 75 Pa·s or less at a resin temperature of 380° C. and shear velocity of 10000 s−1, and
- a weight ratio of low-viscosity polyether sulfone blended in the blend product is 28.6% or more and 40% or less.
