Abstract
A flame-resistant, flowable, pressure-compensating composition is provided. The composition can include a flame retardant such as boric oxide, boric acid, borax, bicarbonate of soda, epsom salt or mixtures thereof. The remainder of the composition can include silicone oil, glycerin or a wax/oil material.
Claims63
A flowable, pressure-compensating composition, comprising:
- a) a liquid;
- b) substantially spherical particles having a diameter of less than about 300 micrometers;
- and
- c) a flame retardant.
A flowable, pressure-compensating composition, comprising:
- a) a liquid comprising a material selected from the group consisting of glycerin, silicone oil and mixtures thereof in an amount from about 25 weight percent to about 75 weight percent based on the total composition weight;
- b) a mineral viscosity-increasing material selected from the group consisting of fumed silica and attapulgite clay and mixtures thereof, in an amount from about 2 weight percent to about 30 weight percent based on the total composition weight;
- and
- c) a flame retardant selected from the group consisting of bicarbonate of soda, epsom salt and mixtures thereof, in an amount from about 5 weight percent to about 30 weight percent based on the total composition weight.
A flowable, pressure-compensating composition, comprising:
- a) a liquid comprising water and an alcohol selected from the group consisting of dihydric alcohols and trihydric alcohols;
- b) an organic viscosity-increasing material selected from the group consisting of gums, cellulose-based materials, soluble oxide polymers and mixtures thereof, in an amount from about from about 0.5 weight percent to about 10 weight percent based on the total composition weight;
- and
- c) a flame retardant selected from the group consisting of bicarbonate of soda, epsom salt and mixtures thereof, wherein said flame retardant is present in an amount from about 5 weight percent to about 50 weight percent based on the total composition weight;
- wherein said alcohol is present in an amount from about 42 weight percent to about 74 weight percent based on the total composition weight and said water is present in an amount from about 1 weight percent to about 8 weight percent based on the total composition weight.
A flowable, pressure-compensating composition, comprising:
- a) wax;
- b) oil;
- and
- c) a flame retardant selected from the group consisting of boric oxide, borax, boric acid, bicarbonate of soda, epsom salt and mixtures thereof, wherein said flame retardant is present in an amount from about 5 weight percent to about 30 weight percent based on the total composition weight.
A padding device comprising a flexible enclosure and a flowable, pressure-compensating composition substantially filling said enclosure, said flowable, pressure-compensating composition comprising:
- a) a liquid;
- b) an organic viscosity-increasing material selected from the group consisting of guar, agar, carboxymethylcellulose, hydroxypropylcellulose, hydroxyethylcellulose, polyethyleneoxide, and mixtures thereof, in an amount from about 0.5 weight percent to about 10 weight percent based on the total composition weight;
- and
- c) a flame retardant selected from the group consisting of boric oxide, borax, boric acid, bicarbonate of soda, epsom salt and mixtures thereof, wherein said flame retardant is present in an amount from about 5 weight percent to about 30 weight percent based on the total composition weight.
A padding device comprising a flexible enclosure and a flowable, pressure-compensating composition substantially filling said enclosure, said flowable, pressure-compensating composition comprising:

- and
- c) a flame retardant selected from the group consisting of boric oxide, borax, boric acid, bicarbonate of soda, epsom salt and mixtures thereof, wherein said flame retardant is present in an amount from about 5 weight percent to about 30 weight percent based on the total composition weight.
A flowable, pressure-compensating composition comprising:
- a) silicone oil;
- and
- b) substantially spherical particles having a diameter of less than about 300 micrometers.
A padding device comprising a flexible enclosure and a flowable pressure-compensating composition substantially filling said enclosure, said flowable, pressure-compensating composition comprising:
- a) a liquid comprising silicone oil;
- b) substantially spherical particles;
- and
- c) a mineral viscosity-increasing material.
