Corecell™ is the leading structural foam core material, which has become widely accepted for the construction of large, high performance structures. It is the latest in foam core technology and although originally developed for the marine industry, it is now used in other applications such as wind turbines and sub sea vessels.
Corecell™ uses SAN polymer base, resulting in unique high tougness and impact resistance characteristics. The foam acts as a 'shock absorber' between the two skins - absorbing the impact without failing, distributing the stresses evenly within the core and, in the case of a boat, ensures it remains watertight even after high point impacts.
Corecell™ foams provide low weight, excellent stiffness, and structural integrity under dynamic loads. They have high shear elongation and retain their mechanical properties even in the higher ambient temperature range.
Corecell™ foams are compatible with polyester, vinylester, and epoxy resins. Corecell™ is type approved by the American Bureau of Shipping (ABS), Lloyds Register of Shipping, Det Norske Veritas (DNV) and Germanischer Lloyd (GL).
The Corecell™ product range provides increased levels of performance, strength, structural integrity and comfort, unmatched by any other core material. Suitable for a wide range of demanding structural applications and different composite manufacturing processes.

Corecell M-Foam – The Marine Foam
• Replacement for PVC cores
• High shear strength combined with low density
• High temperature processing (prepreg compatible)
• High elongation for toughness
• Suitable for all composite processes including prepreg
Corecell M-Foam is the newest addition to the Corecell range and shares the benefits of SAN chemistry common to all Corecell products.
Corecell M-Foam has been developed to deliver one product for all Marine applications. It provides a unique combination of high shear strength with low density, high elongation, high temperature resistance and low resin uptake. M-Foam is the performance leader whether your application is slamming area or superstructure, hull or deck, using hand lamination, infusion or prepreg.
Corecell M-Foam delivers reliable processing through the benefits recognized in all Corecell products of fine cell size and unique knife-cuts giving low resin uptake in infusion processes. For prepreg, M-Foam offers high temperature resistance to allow shorter cure cycles and the confidence to process without fear of inhibition of prepreg catalysis. Where static properties are important, M-Foam delivers market-leading shear strength at a lower density. Where dynamic performance is crucial, the high elongation delivers higher useful properties and the toughness to give impact resistance and superior fatigue performance,
Corecell M-Foam is available in resin infusion format and is compatible with polyester, vinylester and epoxy resin systems.

Metal ores are mainly produced and exist in formation and fracture band of rocks, mostly hard, brittle and broken rocks which are very abrasive. With good diameter keeping ability and abrasion resistant bond, our diamond impregnated drill bits drill fast and last long. The newly developed wire line bits are excellent for drilling holes deeper than 800 metres. Most drill bits are produced with hot press sintering, the bond hardness is HRC26-45
