The present invention relates to a golf tee having the particularity of being 100% biodegradable and density and strength sufficient for the use to which it is destined, the materials making up the mixture not containing heavy metals or toxic elements. The plastic raw material is 100% biodegradable and has a specific weight of between 0.7 g/cm3 and 1.5 g/cm3. The material is composed of bioplastics formed by polymers of vegetable origin such as: rubber, latex, starch, fecula and cellulose, or of biodegradable thermoplastics derived from petroleum composed of biodegradable polymers and elastomeric polymers, such as synthetic rubber, together with a filler of inert and non-toxic minerals from the group of the carbonates and mineral salts, such as calcium carbonate, sodium bicarbonate or barium sulphate, up to a maximum of 50% of the mixture. |
