Silicone window sealing strips We know that nowadays, many industries are using silicone strips due to their excellent sealing performance. This is not only evident in daily life but also in the medical machinery field. However, with so many products on the market, how can we identify whether they are indeed silicone strips? Let's discuss how to identify the components inside silicone window sealing strips.
Non-silicone components can cause certain levels of damage to the storage, production, and physical properties of rubber materials. If the content of such non-silicone components in rubber materials changes, it may lead to instability in the production process and material properties. For example, there are various types of natural rubber trees, and the properties of natural latex collected from each type vary due to differences in the geographical environment, climate, soil fertility, tree crown diameter, season, and frequency of rubber extraction. Consequently, the content of natural silicone rubber and its dispersed gel, aging resistance, sediment, protein, ash content, and other non-silicone component contents produced from it also have significant differences. Therefore, the properties of natural silicone rubber produced by different manufacturers vary, and even within the same manufacturer, the properties of natural silicone rubber produced in different seasons also differ. This variability affects its plasticity, fluidity, physical properties, and the performance of silicone products produced from it, leading to instability in the production process and material properties.

Therefore, it is necessary to test the plastic deformation retention rate (fire resistance rating), nitrogen content, volatile matter content, ash content, sediment content, and color index of natural silicone rubber sealing strips to classify them. Regulations should be established to monitor the content and dispersion of natural silicone rubber to meet the requirements of production and material performance. In addition to siloxanes, silicone also contains residual chemicals, content regulators, structural agents, unreacted residues, and by-products. Copolymerized silicone also has structural difficulties such as the proportion of prepolymer monomers in the molecular chain and cis-trans isomers. Therefore, the production of rubber materials must also adhere to the standards of relativity to ensure the reliability of raw rubber properties. Maintaining the stability of raw rubber properties is one of the crucial factors in ensuring the stability of material properties. Hence, essential testing is required before the use of raw rubber
