SX Grade – High Temperature

Purging Compound For High-Temperature Resin

SX Grade is a high-temperature purging compound for thermoplastic injection molding and extrusion machines. SX Grade is designed to maintain thermal stability at high-processing temperatures while facilitating material and color changes.

SX Grade Purging Compound Features

  • Maintains thermal stability at high processing temperatures.
    SX Grade is olefinic-based and uniquely suitable for purging super-engineering resins above 300°C (570°F).
  • SX Grade purges super-engineering resins.
    The SX Grade purging compound is used exclusively for super-engineering resins such as PPS, PEEK, LCP and Ultem. (VICTREX recommends SX Grade for VICTREX PEEK™ polymers.)

Tips For Proper Usage Of SX Grade ASACLEAN

  • For maximum performance, ASACLEAN should not be diluted with other materials.
  • ASACLEAN does not work by chemical reaction, so there is no soak time or hold-up time required for an effective purge.
  • ASACLEAN works best with maximum agitation – use the maximum safe screw speed and, for thermoplastic injection molding, also use maximum safe back pressure with the screw in the most forward position. (Mechanical Purge Grades)
  • SX Grade should not be left idle in the machine at temperatures above 370°C (700°F) for any amount of time, as decomposition may occur. (Mechanical Purge Grades)
  • Keep the barrel full of SX Grade at all times to prevent oxygen from entering the barrel. Excess oxygen will accelerate material decomposition/carbon formation and could potentially result in fire if at the higher end of the recommended temperature range.
  • To minimize the potential of excessive smoke while purging, it is recommended that a bucket of water be kept near the machine. Place SX Grade purge piles in water immediately after coming back from the nozzle.
  • If processing temperatures are at or near the maximum recommended temperature for the SX Grade, low-to-medium back pressure and screw speed are recommended.
