The Experimental Verification of the Impact of Regrind on Mechanical Properties of Thermoplastics

Abstract:

Concerning with an actual situation in the exploitation of technological waste, this contribution deals with the properties analysis of moulded parts made of thermoplastics containing added regrind. The aim of the experiments was to analyze mechanical properties of plastics with various percentage of added regrind into basic material. Material PBT (polybutylene terephthalate), mineral composite with 30% glass fiber, was used for experimental testing. The plastics specimens were made by injection moulding and tested by chosen mechanical properties. The yield of tested material had tendency to decline with added amount of regrind. Addition of regrind had no impact on change of tensile strength and hardness of tested materials with regrind. The values of Charpy impact test had decreasing tendency with increasing rate of regrind. The utilization of regrind at the production of new moulded parts is important from aspect of reduction plastics waste and pollution abatement of environment.
