High Quality EPS Rigid Foam

Ideal for these applications:

  • Protective Packaging

  • Thermal Protective Packaging

  • Thermal Insulation

  • Structural Insulated Panels

* Here's why we say OPCORE is 'High Quality'.

OPCORE rigid foam is made from 100% virgin material. This means particle-to-particle adhesion is maximized and density is uniform throughout the foam. And, that means better dimensions, better strength, better performance in your application.

Not all white EPS is made from 100% virgin material.

Material Characteristics

OPCORE WHITE rigid foam is used for protective packaging due to it's outstanding impact resistance and crush performance.


OPCORE rigid foam is also a powerful insulating material for it's weight.  It exhibits an R-value of 3.85 per inch of thickness and any given cubic inch of foam will contain about 98% air.

OPCO OPCORE is dimensionally accurate and consistent

Dimensionally Accurate

OPCORE EPS Rigid Foam is dimensionally accurate to 1/32 of an inch in thickness and 1/16 of an inch on dimensions between 4” and 96”.  While this means your product will fit perfectly in every package, the real advantage to you is impact protection is maximized…every time and all the time.

Other notable attributes

  • High compressive strength

  • High load bearing capacity

  • High resiliency

  • Excellent durability

  • Low water absorption

  • Resistant to bacteria & mold

  • Zero ozone depleting potential

  • 100% recyclable and reusable

  • Long-term stable R-value

OPCO, Inc. has recycled millions of pounds of EPS foam. But that’s just part of the story. OPCORE manufacturing processes are designed to utilize recycle content if specified by the customer.. Most importantly, OPCORE is completely recyclable as #6 plastic, right out of the box.
