Production Of Polyurethane From Cellulose That Is Exracted From Citrus Pulp
Polyurethane(PU) has multiple characteristics. PU changed world in 20th century, PU is combining skills like
energy saving, safety, durability so PU being used for many properties in many industry. That PU is produced from
petroleum-based raw materials. Therefore they cause environmental problems. In this study cellulose is extracted from citrus
pulps from juice factory waste and used instead of petroleum-based polyols in production of PU. With waterborne method
bio-based PUs are obtained.
