| Most relevant properties: • Rigid, expanded and closed cell polymer. Structural material designed to support charges and distribute all external forces to the whole area. • High tolerance for heat and chemical exposure. • Remarkable thermal stability can be used in manufacturing processes to at least 120°C with short durations during a cure cycle to over 150°C. Ideal for use with conventional pre-pegs and in some liquid infusion processes where high resin exotherms can often be seen. This stability means also that boat structures such as topsides and decks exposed to direct sunlight, or other sources of heat, will not lose their properties. • Good dimensional stability: the material is not going to be affected by aging due to any secondary reaction causing gaseous compounds to be developed. • Does not suffer from the problems of laminate out gassing or the associated cure inhibition. • Don't contain CFC's, environmentally friendly. • Low resin absorption due its fine cell, saving both weight and cost. • Extremely resistant to impact, slamming and fatigue. High impact absorption without cracking. • Unaffected by water, fuel oil or fluids. • Will not rot and don't change its properties in marine environment. • High thermal and acoustic insulation coefficients. • Good ratio between mechanical properties and density. • Great elongation in shear before failure, making core shear failure in a laminate quite difficult. • Easy to use, resistant to handling damage and easy to machine with conventional tools. • Thermo conformable. • Wide compatibility with all resins commonly employed in composite systems (epoxy, fenolic, polyester,..). • Superior strength and heat resistance than metal or ceramic cores. • Lighter: a sandwich laminate using PVC 75 has the same weight like using STRUCT-CORE 100, useful in transport due increasing of usable charge and spending less combustible. • Non corrosive material, even when it burns there's no corrosive and toxic smoke. |
