Syntactic sphere core

Syntactic sphere core Syntactic cellular core plastics are also called RP syntactic foam or syntactic foam. An RP compound made by mixing hollow microspheres of glass, epoxy, phenolic, etc. into a fluid plastic with its additives and curing agents. It forms a moldable, curable, lightweight mass, as opposed to foamed plastics in which its cells are formed by gas bubbles, etc. 

A syntactic core material made of a 120C curing epoxy film adhesive filled with glass micro spheres and supplied with a lightweight carrier scrim is also available. In the uncured state, the material is in... 

Organic spheres are predominantly polymeric, consisting of synthetic or natural polymers. The field of polymeric nano- and microparticles is vast, comprising, for instance, latex particles for coatings, hollow particles for syntactic foams, and microcapsules for foaming and additive release. In addition, there are core-shell microbeads and coated polymeric particles, where the particles can exhibit multiple functionalities, thanks to the individual features of their different layers 1]. As fillers in thermosets and thermoplastics, hollow microspheres and expandable microcapsules are among the most frequently used in commercial applications.
