Summary: Room temperature vulcanized silicone rubber filled with aluminum trihydrate (ATH) is widely used for electrical outdoor insulation, but it lacks sufficient flame retardancy. Adding graphene nanoplatelets to ATH filled silicone rubber significantly reduces heat release rate and smoke release rate, while maintaining electrical insulation properties. This method is an effective approach to fabricate flame retardant silicone rubber with acceptable electrical insulation performance.

Summary: The flame-retardant micro-encapsulated sepiolite (MSEP) was successfully prepared using the sol-gel method. Various analyses were conducted to confirm the encapsulation of sepiolite. The addition of MSEP and zinc borate (ZB) improved the mechanical properties, flame retardance, smoke suppression, and pyrolysis characteristics of silicone rubber foam (SiFs). SiFs with 3 wt% MSEP and 6 wt% ZB showed enhanced performance, achieving a higher limiting oxygen index value, UL-94 V-0 rating, longer ignition time, lower heat release rates and smoke production, and improved thermal stability.

Summary: In this study, an epoxyfunctional cyclotriphosphazene was used for modifying polyurethane high-solid coatings. The introduction of cyclotriphosphazene resulted in improved thermal stability and flame retardancy of the coatings. The modified coatings exhibited excellent elasticity, impact resistance, and adhesion, but had relatively low hardness. The gloss and hydrophobicity of the coatings were affected by the addition of cyclotriphosphazene.

Summary: Thermoplastic dynamic vulcanizates (TPVs) are synthesized to combine the excellent properties of thermoplastic polyurethane (TPU) with methyl vinyl silicone rubber (VMQ) using an essentially compatibilized method. The hydroxybutane-terminated polydimethylsiloxane (PDMS) block on the TPU increases the microphase separation of the matrix while also enhancing phase compatibility with VMQ. The influence of PDMS on the microstructure and macroscopic properties of TPV has been explored to guide its application in different environments.

Summary: In this study, three fluoroalkyl trimethoxysilane (FATMS) additives with different chain lengths were incorporated into a two-component polyurethane clearcoat to improve its hydrophobic durability. The coatings modified with FATMS maintained their surface hydrophobicity under various conditions, but quickly lost it when exposed to both UV irradiation and/or high temperature with water. The results suggest that the FATMS route is more suitable for indoor applications at room temperature.

Summary: Green flame retardants have garnered attention for their environmental friendliness, but current options fall short in achieving high flame retardancy for flammable polymers and maintaining environmental protection. This study takes a two-pronged approach to address flame retardants and the flame-retardant process. An eco-friendly bio-based synergistic flame retardant (PAU), synthesized using phytic acid (PA) and urea (U), is used to create a flame retardant coating that can be directly applied to any surface shape using polydopamine as an adhesive. The resulting EPS-PAU exhibits excellent flame retardancy, smoke suppression, and light weight while only slightly increasing the density.
