PLASTIC STRUCTURES CONTAINING THERMAL GRADE CARBON BLACK |
摘要 |
Disclosed is a method of insulating a surface or enclosure by applying to th e surface or enclosure a polymeric foam structure of a polymer material and carbon black. The carbon black is generally uniformly dispersed in the polymer matrix in the form of discrete, individual particles substantially free of agglomeration. A preferred carbon black is thermal black. The carbon black is easily processed and integrated into the present structure, and provides a lower thermal conductivity for a given loading. Further disclosed is a process for making the foam structure. Further disclosed is an extruded, insulative foam structure of the type described above.
