However, unstretched polyester molded products have the drawbacks of low heat deformation temperature and low rigidity. Conventionally,
It has been proposed to contain glass II to improve this drawback, and one product has been commercialized. However, when 114 ft of glass is used, although the heat distortion temperature and rigidity are significantly improved, on the other hand, there is a problem that the glass fibers are oriented in the molded product, causing warpage in the molded product, and the product design δ1. : Natsu C was a big problem.

Furthermore, the above polyester molded product containing these glass fibers,
Due to constraints in the installation of doorways, molded products with protruding shapes such as ribs and bosses, which have uneven wall thickness, cause partial depressions called sink marks to occur on the back side of the ribs and bosses. This was a fatal defect in products where appearance is important.
