Since Tenite was first introduced in 1929, it has become a staple of the plastics industry. Tenite is a versatile, durable, and attractive cellulosic plastic. It has been used in consumer product applications from radios and telephones, to toothbrushes and toys.
Tenite cellulosic plastics are noted for their balance of properties – toughness, hardness, strength, surface gloss, clarity, chemical resistance, and warmth to the touch. Tenite products are also easily moulded, extruded, or fabricated and available in natural, clear, amber, and black. Tenite is made from 100% renewable softwood materials.
The mechanical properties of Tenite cellulosic plastics differ with plasticizer levels. Lower plasticizer content yields a harder surface, higher heat resistance, greater rigidity, higher tensile strength, and better dimensional stability. Higher plasticizer content will increase impact strength.
A special feature of the Tenite molded resin is the fact that a fragrance can be incorporated in it. This fragrance can be retained for a longer period of time. This is demomstrated with the mood pebbles, for which Eastman has collaborated with Rotuba. Rotuba are specialised in encapsulating fragrances into plastic materials – and cellulosics are suitable for the process. Unlike other materials, their natural properties allow oxygen to interact with the scent molecules and emit an aroma indefinitely.
