Abstract

Silicone elastomers are widely used in industrial applications due to their mechanical properties and resistance to temperature and chemicals. In the manufacturing sector, particularly in bottle and jar capping machines, silicone is utilized as the base material for rollers operating under high dynamic loads. These conditions often lead to rapid wear and degradation of the silicone rollers during production processes. This study aims to review various literature sources related to the optimal composition and reinforcement methods for silicone elastomers to determine suitable formulations for roller capping applications. The research was conducted through a literature review of scientific journals published within the last ten years, focusing on the influence of filler type, crosslinker type, and composition on mechanical properties such as tensile strength, tear strength, and elongation at break. The review results indicate that a combination of fumed silica (0.2 phr) and clay (1 phr), along with a peroxide-based crosslinker (3 phr), provides the best mechanical performance, achieving a tensile strength of 6.9 MPa, tear strength of 21.5 kN/m, and elongation at break of 315%. In conclusion, the optimal reinforcement of silicone elastomers depends on the type of filler and crosslinking system used, which directly affects the material’s strength, elasticity, and thermal resistance

Abstract

The modern industrial era is characterized by the high complexity of systems and the demand for operational efficiency, making maintenance systems play a crucial role in ensuring reliability, safety, and sustainability of production processes. Reliability-Centered Maintenance (RCM) has emerged as a strategic approach to replace conventional Preventive Maintenance (PM) methods, which are often static and inefficient. This study compares the effectiveness of RCM and PM in terms of maintenance cost and risk through a literature review across various industrial sectors, including power generation, automotive, maritime, food and beverage, and energy distribution systems. The results show that RCM implementation can reduce unplanned downtime by up to 55.77%, increase system reliability by 28%, lower maintenance costs from 20% to 70%, and raise system availability from 57% to over 90% in some cases. RCM has also proven to be more adaptive to actual equipment conditions, supports risk-based decision-making, and is more effective in scheduling maintenance for critical assets. Although its implementation requires more data resources and technical expertise, RCM demonstrates superior long-term performance. This study recommends the integration of a hybrid strategy that combines the strengths of RCM, PM, and predictive approaches powered by digital technologies to comprehensively enhance the efficiency and reliability of maintenance systems.
