Abstract
The invention discloses a modified PA66 formula. The modified PA66 is composed of a nylon 66 body, stearic acid and phenolic aldehyde, wherein the nylon 66 body accounts for 40%-48% of the modified PA66 by mass percent, the stearic acid accounts for 30%-36% of the modified PA66 by mass percent, and the phenolic aldehyde accounts for 22%-24% of the modified PA66 by mass percent. Therefore, the modified PA66 has the advantages of no shrinkage and no embrittlement in a low-temperature environment.
Description
Technical field
The present invention relates to plastics field, particularly relate to a kind of nylon 66.
Background technology
