“…Interest in these materials has increased mainly due to the ability to change mechanical properties and adapt them to specific operating conditions. The process of mixing polymer with polymer has always been one of effective methods for producing compositions with predetermined properties [1][2][3].…”

The article presents results of research into the influence of aluminum hydroxide concentration on properties and crystallization regularities of composite materials based on mixtures of high and low density polyethylene. Studies were carried out with samples containing 1, 3, 5 and 10 % wt. aluminum hydroxide. All composite materials were based on mixtures of high and low density polyethylene, taken in 50/50 ratio. Dilatometric studies were carried out on an IIRT-1 device in the course of stepwise cooling of samples with a load of 5.3 kg. Temperature dependence of the specific volume, density and free volume of composite materials established. Also, density of compositions at a temperature of 190°C was identified on a capillary rheometer of CEAST MF50 brand. Onset temperature of crystallization and approximate glass transition temperature of composite materials were determined. Physical-mechanical properties of composites, such as ultimate tensile stress and elongation at break, were studied.
