Dimensional Stability After Molding: Part 4 | Plastics Technology

Mar 25, 2013·Water is a plasticizer for nylon. This means it reduces the material’s glass-transition temperature. For workhorse polymers nylon 6 and nylon 6/6, this takes the glass transition from 65-70 C down to about 10 C. Water has the same hydrogen bonding as nylon; when water enters a nylon part it has the same opportunity to become loosely attached to the …

How to solve the problem of painting on blow molded parts

Annealing or whole surface treatment can be used to eliminate stress. Annealing treatment is to heat the plastic parts below the hot deformation temperature, 60 degrees, keep on two h. A solution that eliminates the internal stress of plastic parts can be disposed of at room temperature by 15~20min treatment on the surface of the plastic parts. 2.
