Compatibilizer for composite materials
What is MARICOM®?
・This is a masterbatch of compatibilizer based on polyethylene resin.
・Blending of compatibilizer “MARICOM®" allows for kneading
between normally incompatible resins or with an incompatible filler.

Applicable materials and effects
Composite material
It is effective for various materials and it can be applied even when it contains three or more kinds.
- Resin type: Polyolefin such as PE, polyester such as PET, polyamide such as PA6
- Filler type: Wood flour such as cellulose, inorganic such as talc
Modification of resin
The following effects can be given by adding to polyester resin such as PET.
- Improvement of brittleness by improving impact strength
- Improvement of extrudability by increase of melt viscosity

Application to composite resin waste recycling
Blending of MARICOM with wasted resin composites such as laminated film, which have been traditionally difficult to be recycled, enables them to be recycled to a resin with practical physical properties.
