Product Description
IOTA 9502 Vinyl POSS
Product name:
Vinyl silsesquioxane; Vinyl POSS; Octavinyl POSS; Octavinyl octasilsesquioxane
English name:Poly(Vinyl Silsesquioxane)
Structural formula :
Performance and use:
01 Application in the field of heat resistance
POSS has a significant effect on improving the heat resistance of the matrix through cross-linking modification or nanocomposite. Studies have shown that using POSS as a cross-linking agent to modify polymers such as epoxy resin, polyurethane, polyamide-imide and fluoroolefin vinyl ether resin respectively can significantly improve the heat resistance of the polymer matrix. Through nano-hybrid composite method, POSS can improve the heat resistance of materials such as nanocellulose, heat-resistant resin, polydimethylsiloxane and phenolic resin to a certain extent.
02 Application in flame retardant field
Due to the stable structure of Si-O-Si, POSS will form a dense silicon oxide film layer at high temperatures, which can effectively prevent the escape of small molecules and thedripping of molten droplets after the polymer is cracked, and block the transfer of oxygen and heat to the interior of the polymer. , thereby improving the flame retardant properties of polymer materials. POSS has an inorganic silicon core and a designable organic R group. As a new type of halogen-free nano-flame retardant, it is widely used in the flame retardancy of epoxy resin, polyester, polyamide and other polymers. According to the structure and properties of POSS itself, there are condensed phase flame retardants based on -Si-O- type ceramic layer barrier and -Si-O-P- and other bridging effects; through the design of POSS side chain functional groups, the blow-out effect can be achieved Flame retardant; in addition, the flame retardant R group of POSS combined with nanomaterials such as graphene and boron nitride nanosheets can achieve synergistic flame retardancy in the condensed phase and gas phase.
