| Abstract: | The technical index of quality control and process parameters for preparing a kind of high density polyethylene(HDPE) speciality resin,grade 6360M,for underground drainage pipe were determined in accordance with requirements stipulated in the related European standard and China national standard.HDPE 6360M successfully produced in a HDPE slurry plant possessed superior physical properties,good processability and high environment stress cracking resistance(ESCR).With tensile strength over 25 MPa,flexural modulus above 1 200 MPa and ESCR(F50) longer than 1 000 hours,HDPE 6360M passed the test of resistance to internal pressure. |
