Material performance
1. The material performance of the Granulation screw is mainly manifested as excellent electrical insulation (especially high-frequency insulation), white hard and brittle, metal sound when dropped on the ground, light transmittance second only to organic glass, coloring and water resistance Good chemical and chemical stability. It has excellent flame retardancy and is a non-combustible plastic.
2. The strength is average and the rigidity is very good, but the quality is brittle, it is easy to produce stress cracking, and is not resistant to benzene. Gasoline and other organic solvents. The long-term use temperature can reach 260 degrees, and it is stable in 400 degrees of air or nitrogen. After being modified by adding glass fiber or other reinforcing materials, the impact strength can be greatly improved, the heat resistance and other mechanical properties are also improved, the density is increased to 1.6-1.9, and the molding shrinkage is less than 0.15-0.25%. Production of heat-resistant parts. Insulation parts, Dao chemical instruments, optical instruments and other parts.
Molding performance
1. Amorphous material, small moisture absorption, but should be shaped after drying.
2. The fluidity is between ABS and PC, solidification is fast, shrinkage is small, and it is easy to be divided into solutions. The mold temperature is 100-150 degrees. The taper of the main flow channel should be large, and the flow channel should be short. Scope of application Generally, it can be used to manufacture PPS pipe, PPS sheet and other materials, and is mostly used in construction and home furnishing.
