What does "stress hardening" of plastic molding mean?
The plastic molding is various forms (such as powder, granules, solution and dispersion) of plastic products or parts required for the shape of.
Plastic stress hardening phenomenon, refers to the plastic molding process, with the orientation of the increase of intermolecular forces increased, causing the polymer viscosity, the polymer showed "hardening" tendency, the deformation tends to be stable and no development. This phenomenon of orientation process becomes "stress hardening"".
Plastic (Plastics): plastic material, the so-called plastic refers to the external force of the deformation occurs, the external force can be maintained after the abolition of the state of force. The elastic modulus of plastic is between rubber and fiber, and it can deform in a certain way. Soft plastics close to rubber, hard plastics, close to fiber.Plastic refers to the resin (or in the process of using monomer polymerization) as the main ingredient, such as plasticizers, fillers, lubricants, additives such as colorants as auxiliary components, can flow in the process of forming materials.
