Braskem RA34U3 LLDPE Rotomolding Polyethylene  (discontinued **)
Categories: Polymer; Thermoplastic; Polyethylene (PE); Linear Low Density (LLDPE); Linear Low Density Polyethylene (LLDPE), Rotational Molding Grade

Material Notes: The resin RA34U3 is a linear low-density polyethylene, 1-butene based, with a good balance of processability, environmental stress cracking resistance, and impact strength. It contains long term UV6 stabilization and antioxidant additives. This resin is used to produce rotomolded parts for general use applications, kayaks, toys, and parts for the agricultural and automotive segments. This resin is recommended for rotational molding under conditions comparable to polyethylene resins with a similar melt index and density range. Oven Temperature Range: 220 to 350 ºC.
