Abstract: A sealant composition especially useful for stopping punctures in vehicle tires includes: (a) a viscous fluid such as propylene glycol or polypropylene glycol; (b) one or more fibrous materials such as cellulose, wool, nylon, rayon, hair, wollastonite, rock-wool, glass wool fibers, polyester, polypropylene, or other material of like nature; and (c) flat plate-like particles, such as mica. In one embodiment, the composition is too viscous to be readily passed through a pneumatic tire valve stem, so the viscous product is installed into the tire while the tire is dismounted from the wheel. In another embodiment, the composition is made of two parts, each of which is sufficiently low in viscosity to pass readily through the valve stem, but which react on mixing inside the tire form a liquid of higher viscosity.

Abstract: A composition of matter comprising at least 2% by weight of a fibrous material and at least 30% by weight of a binding material such that the composition can be melt-molded into articles which have mechanical strength sufficient for their intended uses and which are biodegradable. The binding material is formed of natural substance and may also include up to 30% by weight synthetic, water-soluble polymer. The fibrous material may be cellulose and/or mineral fibers which provide the attributes of reinforcement and degradability. The composition may further include up to 20% by weight liquid or solid plasticizer which serves to lower melt viscosity and add toughness to the composite material.
