High Ductibility – Low Cost PMI Rigid Foam

A PMI-based Core material


HyboCORE® based on PMI have proven their worth, particularly at high processing temperature and pressure. They are very easily process and provide considerable cost saving in composite manufacturing.

Property of HyboCORE ®:
A polymer cell foam, based on Poly Methacrylic Imide(PMI).
Free from CFC.
Homogenous and isotropic.
100% closed cell.

HyboCORE® is a kind of rigid foam based on poly (methyl methacrylate), which is free of halogen. The product has a small and uniform pore size (0.3 mm-0.5 mm).


Excellent Ductibility


In particular, HyboCORE® has excellent Elongation at break. Compared with the traditional PMI foam 4-5%, HyboCORE® can up to 18%. Under the premise of ensuring the basic foam mechanical properties, it greatly improves the foam toughness, and optimized the conventional confliction of processing performance and impact strength. HyboCORE® can withstand the shock absorption / concentration load, to ensure the integrity of sandwich structure under impact, and expand the damage tolerance and damage visibility of composite structures.

Free to Processing


HyboCORE® can withstand the maximum 150°C temperature and maximum pressure of 0.5MPa, and suitable for middle temperature co-curing processing. In order to adapt to the different sizes and shape of the workpieces, HyboCORE® can be easily shaped in press-molding, and bonded with variety of adhesive, or common CNC machine freely.

HyboCore® is very competent on material cost, which is close to PVC foam core. Providing similar purchasing cost budget, the customer can take higher curing temperature and faster speed, which resulted into lower processing and manufacturing cost.
