Description
Bismaleimides resins made from bio-based- Features
- Swancor Bismaleimides resins made from bio-based offer two product specifications with bio-content of 42% and 67% according to ASTM D6866-22.
- The self-cured thermoset with 42% bio-content performs Dk=2.54 and Df =0.0044 at 10 GHz, and Tg measured by DMA is about 188 ℃.
- The self-cured thermoset with 67% bio-content performs Dk=2.22 and Df =0.0027 at 10 GHz, and Tg measured by DMA is about 91℃.
- The material can be used as a low dielectric constant co-curing additive, and performs good flexibility after self-curing, to improve the toughness of materials in CCL and RCC.
