PREMIUM EXTRUSION AND RIGID PACKAGING RESINS
Marlex® HMN TR-945 / HMN TR-945G
HIGH DENSITY POLYETHYLENE

These hexene copolymers are tailored for rotational molding applications that require:
  • Wide process windows and excellent flow
  • Long-term UV stabilization
  • Good impact strength
  • High modulus
  • Fair ESCR
    • These resins are available in:
  • Pellet form - HMN TR-945
  • 35 US mesh powder - HMN TR-945G
    These resins meet these specifications:
  • ASTM D4976 - PE 233
  • FDA 21 CFR 177.1520(c) 3.2a, use conditions B through H per 21 CFR 176.170(c) Table 2.  Single use articles contacting food types I, II, IV-B, VI-A, VI-B, VII-B, and VIII.  Repeated use articles contacting all food types defined in 21 CFR 176.170(c) Table 1.
    • Typical applications for HMN TR-945 and HMN TR-945G include items such as:
  • High modulus parts - e.g. Ductwork
  • Large tanks

    1. The nominal properties reported herein are typical of the product, but do not reflect normal testing variance and therefore should not be used for specification purposes.  Values are rounded. 
    2. The physical properties were determined on compression-molded specimens that were prepared in accordance with Procedure C of ASTM D4703, Annex A1.
    3. Properties were measured on rotational molded samples with 1/8” (3.17 mm) average thickness, unless otherwise noted. The average peak internal air temperature during molding was 400ºF.
