PP-R Pipe Processing Temperature

Since polypropylene is a typical crystalline polymer and its melt viscosity is sensitive to temperature, processing temperature control is very important in the extrusion molding of PP-R pipes. The molding temperature is generally controlled at 210~260°C. If the extrusion temperature is too high, it will cause the material to accumulate at the die orifice, which will cause the degradation of the raw material and reduce the performance of the pipe products.
