TOKYO (ICIS)--Daicel Polymer has developed new cellulose bioplastics based on “non-edible wood resources”, and plans to put the products in the market by late 2012/early 2013, the Japanese plastic producer said on Wednesday.
The new products, CELBLEN EC, are cellulose esters containing 40-50% plant-based materials derived from wood pulp, the company said.
According to Daicel Polymers, the new cellulose bioplastic has an advantage in procurement of raw materials compared with corn-derived polylactide (PLA) because cellulose abounds and is available everywhere in nature.
“Conventional cellulose ester-based plastics are at a disadvantage in dimensional change or warpage after long-term storage resulting from volatilization of plasticizers,” the company said.
“CELBLEN EC is greatly improved in those disadvantages by applying new plasticizers, original formulation technologies, and advanced compounding technologies, and have excellent mechanical properties suitable as moulding materials,” it added.
Daicel Polymer expects the general-purpose grade of CELBLEN EC to be in the market by the end of 2012, and a clear grade and flame-retardant grade in early 2013, it said.
