发明名称 Use of a microcrystalline polyamide to obtain a particular surface finish
摘要 The present invention relates to the use of a microcrystalline polyamide for obtaining an object having all or part of its outer surface formed from this microcrystalline polyamide and having a particular surface finish, in which: the manufacture of the object comprises steps carried out hot between the Tg (glass transition temperature) and the Tm (melting point) of this microcrystalline polyamide; the transparency of the microcrystalline polyamide is such that the light transmission at 560 nm on a polished object 1 mm in thickness is greater than 80%, advantageously greater than 88%, the transparency being measured on the object obtained by standard processing methods, such as injection moulding and sheet extrusion/calendering.
