Huntsman Corp.'s polyure¼thanes division has debuted two grades of unplasticized soft thermoplastic polyurethanes.
Huntsman of The Woodlands, Texas, said the materials are ideal replacements for PVC where the presence of phthalates or other plasticizers are undesirable. Irogran A60E4902 is a polyester with Shore 55A hardness while A65P4910 is a polyether with Shore 65A hardness.
Huntsman claims the materials are not tacky, do not exude a surface film and maintain properties without migration. They have good drape and hand with a supple feel, Huntsman claimed.
Other benefits are high elastic recovery, high clarity and good tear and abrasion resistance, according to Huntsman.
The resins are suited to extrusion, injection molding and film production
