Our WEVOSIL products are used in applications requiring a wide operating temperature range and high elasticity. Along with high thermal conductivity, this makes them ideal for thermal management applications and targeted heat removal from modules.

Some WEVOSIL products are flame retardant and have UL 94 V-0 approval. Their adaptability for process and curing time provides a high degree of flexibility in production processes. Good elasticity also makes them suitable for use in mechanically demanding applications.
