Abstract

The high performance properties of Polyamide 6 and Polyamide 6.6 thermoplastics create a serious area of use in various sectors such as automotive, railway, textile, construction and electronics. High mechanical strength performance, easy processing properties and high thermal resistance performance are the advantages of this group of thermoplastics. High moisture absorbency, low dimensional stability, low temperature impact strength, and being easily flammable can be considered among the disadvantages of these thermoplastics. Structural disadvantages are also reflected as a problem in the final products and limit the wide usage areas of polymers. In recent years, acrylonitrile-butadiene-styrene (ABS) has become a widely used thermoplastic polymer due to its good mechanical properties, high chemical resistance, and easy process applicability. ABS also has some disadvantages that limit its usage areas. Natural flammability and toxic gas emission together with dense smoke are among these disadvantages. Increasing the flammability performance of ABS by using halogenated additives and antimony synergists has been a very common method in the past. However, with the awareness of environmental sensitivity, the use of halogen-containing additives has been severely limited over time. Therefore, the development of halogen-free ABS composite materials with improved flame retardant properties is a serious problem nowadays. A twin screw extruder and an injection molding machine were used in this study. ABS –based composites were prepared by adding phosphinate and polyphosphate halogen-free flame retardant additives at a total of 20, 25, 30% by weight in the ABS matrix. The characterization and performance studies of the produced samples were evaluated with the test results carried AEGEAN SUMMIT 4th INTERNATIONAL APPLIED SCIENCES CONGRESS ABSTRACT BOOK ISBN: 978-625-7341-89-9 www.egekongresi.org Page | 20 out within the framework of certain standards such as UL 94 and IEC 60695-2-12.
