  • * The property values in this table are representative values obtained from a injection specimen based on the prescribed testing methods. These values do not show standard values.
  • * The test specimen follows JIS K7139:1996 (ISO 3167:1993), the creation conditions follow JIS K7152:1999 (ISO 294-1:1996).
  • * RYULEX has water absorbing properties and therefore requires pre-drying. The recommended drying conditions are 100°C for 3 to 4 hours.
  • * RYULEX does not have compatibility with other styrene-based resins, so use care not to mix it with other styrene-based resins.
  • * Please use this resin by first checking its suitability (strength, heat resistance, oil resistance) in advanced by practical testing that corresponds to the intended use.
  • * Please contact DIC regarding product numbers other than A-14.
  • *1: Melt mass flow rate measurement conditions: 230°C, 3.8 kg (JIS K 7210 N Conditions).
