PENCILS CONTAINING RECLAIMED RUBBER

摘要

Pencils are disclosed that have an outer sheath comprising a base elastomer and reclaimed rubber for enclosing an inner marking core therein. The base elastomer provides a vulcanizate with basic physical and environmental resistant properties including at a miinimum elasticity, flexibility, and relative impermeability to water and air while the reclaimed rubber advantageously extends the base elastomer to reduce cost and help reduce quantities of existing environmentally harmful waste. By not incorporating wood in the sheath, the present invention does not contribute to deforestation or consumption of a natural resource, but to the contrary, describes an efficient use for used tires. In addition, the pencils of the present invention are easier to manufacture than wooden pencils and generate less health hazards.
