Abstract
It is known that binary ethylene-propylene rubbers are vulcanised using peroxide systems. A considerable advantages of chlorinated ethylene-propylene rubbers over the unmodified forms is that they can be vulcanised by the normal vulcanisation method for u

Abstract
A study is reported of the ozone resistance and flammability of halogenated ethylene-propylene rubbers and EPDM, and of their blends with different rubbers. For combination with highly unsaturated rubbers, use was made of chlorinated EPDM with ethylene no

Abstract
A study was made of the influence of the acoustic treatment time on the properties of polyesters and polyurethanes based on them. The effect of the acoustic treatment was assessed from the value of the viscosity measured on a Hoeppler viscometer. The incr

Abstract
In order to improve the adhesion between rubber and brass-coated metal tyre cords, the effect of coprecipitated Ca/Co and Ca/Ni hydrosilicates was investigated. In this article, it is demonstrated that the combined use of cobalt (nickel) hydrosilicates wi

Abstract
The efficient use of energy in the decrystallisation of rubber feedstocks in the manufacture of tyres is addressed. During decrystallisation of stored rubbers, the rubber is steam heated to a temperature above the meting point of the crystalline phase. In

Abstract
The threaded part of a screw can be divided into three zones: the feed zone, the buffer zone and the thrust zone. The main zone is the thrust zone where the process of rubber mix preparation prior to extrusion takes place. In this zone, over 90% of the po

Abstract
Sources of butyl rubber reclaim are waste tube diaphragms from tyre works. Since the cost of butyl rubber is higher than normal diene rubbers, its partial replacement in rubber compounds with reclaim gives a considerable cost benefit. This article examine

Abstract
When subjected to tensile or compressive cyclic load, elastomeric materials experience damage known as the Mullins effect. To handle the physical effects by means of finite element method, the constitutive law for superelastic materials can be expressed u
