Nida-Core Corp.is pleased to introduce structural welded and non-welded quality PET foam core in plain and scored sheetstock. NidaFoam exhibits excellent fatigue and chemical resistance and is noted for its excellent
burn characteristics and superior high temperature tolerance. Thermoformability: NidaFoam sheets can be thermoformed. The white color of the NidaFoam is easy to recognize and distinguish from other available foams. The white color transfers less to the composite part surface, resulting in less gelcoat usage.Chemical resistance and corrosive gases: Good resistance against weak bases, weak acids as well as against most current solvents : alcohol – acetone – perchlorethylene. Limited resistance–check in each case – against strong mineral acids. NidaFoam does not emit any corrosive gases, even when burned, unlike PVC foams. NidaFoam does not emit gases that contain halogen such as hydrochloric acid. Water and resin absorption: excellent closed cell ratio, comparable to PVC, PU and SAN foams. Certifications: NidaFoam has been awarded FST M1 spec burn certificate. Other industry specific certifications are pending and available upon request. Independent laboratory structural testing results available. Scrimming and scoring,including grid pattern for infusion laminar resin transfer is available with NidaFoam.
