Typical Operating Conditions of Elastomer AR Compounds

1.Typical Operating Conditions

Typical operating conditions are representative ones.
Extrusion molding of AR-FL series are film molding conditions.

2.Drying resins

AR Elastomers essentially do not require preliminary drying except for the fusion grade (AR-BOI Series and AR-BOE Series only). They are to be dried at 70℃ to 80℃ for 2 to 3 hours.


The gate shown in Figure A may fail due to jetting. B- or C-type gate is recommended.


  • Designing a mold can be essentially the as same as that of olefin resins. It may not be well released only by extrusion pins for its soft material and product shape. In this case, we recommend using a combination of air and a stripper plate.
  • For gas release, secure 1/100 mm to 2/100 mm.
  • Flow marks may be caused, so we recommend a stain finish or a grain finish for the product surface.

5.Molding machines

AR Elastomers can be used to perform molding using an extruder or an injector for olefin resins or styrene resins. Special facilities are not required.
