Cause of winter break in nylon tie

- Nov 13, 2017 -

Winter arrived, we all know that plastic this thing will become very brittle after the winter, because the main component of plastic is macromolecules aggregates, macromolecules are characterized by low temperature movement, high temperature when the movement is fast. In winter, the molecular movement is slow, when the plastic is external force, the object deformation, because the molecular movement is slow, the external force is not easy to pass away (all the stress) or consumption (molecular chain friction), so easy to produce internal stress concentration, when the internal stress to a certain extent, the large molecules are broken, causing cracks, cracks will be induced by stress concentration and spread, The plastic is broken.

Treatment: In general, a small amount of water can be injected into the bag to reduce the fracture.
