Excellent Impact Absorption and Damage Tolerance

CoreCork® is a natural energy absorber, perfect for high impact strikes such as rail front ends and impact prone areas on automobiles and rail cars. The sail and surfboard market have discovered CoreCork®'s ability to absorb energy and produce lower fatigue. The canoe and kayak industries are taking advantage of cork's natural ability to absorb rock and beach impact.

Reduced Thermal Conductivity and Excellent Dampening

CoreCork®'s natural closed-cell structure provides exceptional dampening and dramatically reduced thermal conductivity.

Excellent Fire, Smoke and Toxicity Properties

CoreCork® passes the E84 'Tunnel Test' and CoreCork®'s new NL 11 product meets the M1F1 Classification.

Superior Print-Stopping Capability

CoreCork® absorbs less resin and retains its laminated thickness resulting in a 25% reduction in cost vs. bulker mats.

Environmentally Superior

The bark of a cork tree is harvested without harming the tree every 8 years, and most trees live for 150 years. Amorim's cork plantations are absorbing 218,000 TONS of CO2 from the atmosphere every year.

User Friendly

CoreCork® bonds with all standard laminating resins: PE, PU, VE, Epoxy, Phenolic. High processing and working temperature. Works with most prepregs. Excellent Styrene resistance works well for resin infusion with low resin uptake, retains its thickness under vacuum pressure.

Competitively Priced Vs. The Competition

CoreCork® is priced lower than many pvc and bulker mat products, and is competitively priced vs. balsa products.

Does Not Absorb Water and Does Not Rot

Only the damaged or outermost cells of cork absorb water. CoreCork® is a naturally closed cell wood fiber material that does not absorb water, does not rot and does not decay over time. This leads to enormous long term advantages vs. competing products, which do transfer water and can be susceptible to rotting and decay. CoreCork® has an excellent resistance to fungus growth compared with other core materials.

Time and Labor Savings

CoreCork® can be easily cut with standard cutting tools and saws.

Excellent Conformability

CoreCork® is available in scored sheets and rolls (thicknesses less than 3/16 " and 5mm).

Compression Recovery

CoreCork® will recover up to 85% of original thickness in a severe impact situation, and 100% in most impacts. Core Cork rarely delaminates on impact.

Process Friendly

CoreCork® works well in hand lay-up, infusion, rtm and prepreg.
