FAQ
Q: What are the advantages of this resin over ordinary epoxy resin?
A: The advantages of crystalline biphenyl epoxy resins are their higher thermal deformation temperature and better chemical resistance. Due to the structure of biphenyl rings, the resin forms a more stable crystalline structure, which makes it maintain good mechanical properties and dimensional stability under high temperature environment.
Q: What is your general delivery time?
A: It depends on the model you need and our inventory. We generally have some stock of commonly used models, and the delivery time is generally 3-15 days.
Q: What are the specific applications in the electronic and electrical industry?
A: In electrical industry, crystalline biphenyl epoxy resins are often used to make advanced circuit boards, semiconductor packaging materials, high-voltage insulation materials and high-frequency electronic device packaging. Its high heat resistance and low dielectric constant make it ideal for applications where thermal stability and electrical performance are critical.
