Description
Product Description
This product is made of high-purity heat-conducting alumina modified by advanced technology and special process. Compared with ordinary heat-conducting alumina, this product has the following characteristics:
1. High filling capacity. After surface treatment, the product has low oil absorption, good fluidity and high filling capacity.
2. Excellent processing performance. After surface treatment, the powder has good dispersibility, fluidity and processability in silicone rubber and plastics.
3. Good mechanical properties. After surface treatment, the powder has good dispersibility and compatibility in silicone rubber and plastics, therefore, it has good mechanical properties.
Typical usages
It is used in heat-conducting ceramics, heat-conducting plastics, heat-conducting silicone rubber (including heat-conducting silicone gasket, heat-conducting sealing adhesive, heat-conducting double-sided adhesive, heat-conducting silicone grease), heat-conducting grease adhesive, epoxy resin sealing adhesive, etc.
