1. Introduction

DURACON® POM acetal copolymer is a highly crystalline engineering thermoplastic. Its excellent mechanical and physical properties, as well as its superior moldability, allow for its use in an increasing range of applications.

DURACON can be injection molded, extruded, blow molded, and compression molded. Injection molding is the most widely used process. This bulletin describes injection molding of DURACON in detail, including procedures which are efficient and economical yet make the best use of DURACON's high strength, excellent characteristics, and dimensional accuracy. This bulletin mainly describes unfilled grades (M90-44: the general purpose grade, M270-44: the high flow grade, M25-44: the high viscosity grade) which are the most widely used. Unless otherwise indicated, tables and figures correspond to grade M90-44. There are many different grades of DURACON, classified into unfilled grades and filled grades, with the latter containing glass fiber reinforcement or other fillers. For details of these grades, please refer to bulletins on the individual grades.
