PE & PP Materials and Additives - LLDPE COLORED ROTOMOLDING GRADE

SCG™ LLDPE M9001RW and M90 are linear-low density polyethylene (LLDPE) for rotational molding applications.

 

These grades are suitable for rotational molding of large water tanks and parts that require high stiffness.

Product Characteristics

• High stiffness and impact strength
• High thermal stability up to 1 to 1.5 hours of heating
• High UV protection (UV20) for outdoor use.
