Abstract
A microwaveable exercise putty includes a borosiloxane or stannosiloxane reaction product. The resulting reaction product is mixed with a second polysiloxane, an internal lubricant such a monounsaturated fatty acid, and a particulate material which creates heating upon subjection to microwave energy. Precipitated silica is a particularly preferred particulate material. The exercise putty may be manipulated by patients, and at the same time is capable of delivering heat to the body part undergoing the manipulation.
Claims13
A microwaveable exercise putty, comprising a mixture of:
- 100 parts by weight of a chain-extended polysiloxane reaction product formed by reacting a polysiloxane having a viscosity of 50,000 to 100,000 centistokes with a reactant containing oxygen and either boron or tin;
- 10 to 50 parts by weight of an unreacted, uncured second polysiloxane having a Williams' plasticity in the range of 120 to 140 mm;
- 0.2 to 2.0 parts of an internal lubricant;
- and
- 5 to 45 parts by weight of a particulate material susceptible to substantial heating when subjected to microwave energy, and selected from the group consisting of metals, metal oxides, carbon black, clays and compounds and complexes containing bound water.
A microwaveable exercise putty, comprising a mixture of:
- 100 parts by weight of a borosiloxane reaction product formed by reacting a hydroxyl end-stopped, polydiorganosiloxane having a viscosity of 50,000 to 100,000 centistokes with trimethyl boroxine;
- 10 to 50 parts by weight of an unreacted, uncured second polysiloxane having Williams' plasticity of 120 to 140 mm;
- 0.2 to 2.0 parts of octadecenoic acid;
- and 5 to 45 parts of precipitated silica.
