1785-64-4 - Reference Information
| perelin materials | perelin type materials have been widely used in electronic products. the material types with commercial value in perelin family are mainly divided into 4 types, namely perelin n, perelin c, perelin f and perelin Ht. Perelin Ht(SCS calls it parylene -AF4,KISCO calls it parylene -SF4). Due to the limitation of its production process, the preparation efficiency is very low, making it very expensive, with a unit price of more than US $10,000 per kilogram. After Ht powder is coated, among the four kinds of perilin, high temperature resistance, ultraviolet resistance and other properties are the best. In most cases, it is used in the military industry system, but it is rarely used in the civilian market. In addition, it has the following obvious disadvantages: 1. Raw materials are difficult to obtain in large quantities. Due to technological limitations, there is no factory in the world that can produce 100 kilograms. In addition, due to the possible application to the military industry system, the United States has always adopted an embargo on the mainland market. 2. Low film formation rate. Ht powder has a lower film formation rate on the surface of the object than N, C and F due to the high activity of the monomer after cracking. 3. The equipment requirements are high. Due to the high monomer activity after cracking, the temperature of the deposition chamber needs to be reduced, and the existing Perelin equipment needs to be specially modified. With the increasing requirements for waterproof materials and increasingly stringent environmental protection policies, the traditional Perelin N and Perelin C are far from meeting the market requirements in terms of high temperature resistance and UV resistance. It is very meaningful to develop a material similar to Ht powder. |
