Rulon Bearings

Braskem RC35U4 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 RC35U4 is a linear low-density polyethylene, 1-butene based, with high stiffness and an adequate balance of processability and environmental stress cracking resistance. It contains long term UV8 stabilization and antioxidant additives. This resin is used to produce rotomolded water tanks and parts for the automotive and agricultural 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.
