Surface modification of aluminum trihydroxide to enhance arc and acid resistance of silicone compounds

High temperature vulcanization (HTV) silicone rubber is the polymer of choice with regard to housing material for high voltage applications. The requirements are challenging due to harsh environmental conditions like UV irradiation, humidity, industrial pollution, etc. The tracking and erosion performance of the compound needs to be evaluated to ensure the long term performance of the high voltage insulator. Another key aspect to increase the durability of the insulator is the resistance against nitric acid, as this is formed by a combination of unavoidable corona discharges in overhead power lines and atmospheric humidity.

Evaluation of crosslinking coagents in HCR silicone

CR silicone՚s unique properties allow it to be used in many niche ways. These unique properties include temperature stability, weatherability, compatibility and processing ease. Silicone has a very low starting durometer in its raw state. High levels of reinforcing filler are typically needed to obtain high durometer specifications. Additionally, physical properties of silicone are generally lower than most other elastomers. This can often cause difficulties in meeting tear, modulus, compression set or dynamic property application requirements. Application segments for silicone include automotive, wire and cable, architectural,
aerospace, consumer products and medical devices.
