METHOD AND APPARATUS FOR PRODUCING POLYBUTYLENE TEREPHTHALATE FILM, AND SHAPE-MEMORY POLYBUTYLENE TEREPHTHALATE LAMINATED FILM |
| 摘要 |
A method for producing a polybutylene terephthalate film by an air-cooled inflation method of inflating a tube of a molten polybutylene terephthalate resin extruded from an annular die by the injection of air, the resin-extruding pressure being 8.3 to 13.7 MPa, and the resin-extruding temperature being a temperature ranging from the melting point of the polybutylene terephthalate resin - 15 DEG C to the melting point - 5 DEG C. <IMAGE> |
