Abstract
This study deals with high-density polyethylene (HDPE) which was subjected the drop-weight test. HDPE is a semicrystalline thermoplastic polymer which is commonly used in many applications and mainly in the automotive industry because of its properties. The injection moulded HDPE samples were subjected the penetration test at different potential energies and the results were subsequently evaluated and discussed. The samples were tested in the range of potential energies from 30 to 230 J. The first sample penetration occurred at the energy 50 J. It was found out that the potential energy 30 J is too small for penetration of this material, which shows the impact resistance of HDPE.
Highlights
Polymers in comparison with small molecules have rare properties that are very often difficult to predict
This study is concentrated on impact resistance of high-density polyethylene (HDPE) against penetrator with different potential energies
Injection moulded HDPE samples were penetrated by penetrator with potential energies in the range from 30 to 230 J and the results were subsequently evaluated
Summary
Polymers in comparison with small molecules have rare properties that are very often difficult to predict. Multilayer films, nanomaterials, electronic devices and electrooptical are being developed in modern polymer science for end-use performance evaluation. These applications require much more complex and specialized testing [1]. Polyethylenes are commodity polymers which account for more than 70 % of total plastics consumption and are low cost, processable and available. Properties of the composites which are of a practical importance They used 0.15 % each of complex antioxidants and light stabiliser together with a copolymer of ethylene with vinyl acetate and linear lowdensity polyethylene to achieve the stabilization of HDPE blend [5]. At the end crack surface after the test of each height was evaluated
