Experts Take You Quickly to Understand Polymer Orientation

As a Customized PP Tube Core Factory, let's share with you the knowledge about polymer orientation.

The orientation of the plastic molecules is affected by external forces, the polymer chains are stretched and elongated, and the spherical crystals are also elongated. Molecular orientation is a deformation under the action of external force, and the deformation of the molecule can increase its tensile strength and impact strength.

However, the tensile strength decreases in the vertical direction of the orientation, and the impact strength also decreases, so that the molecular orientation is directional. Plastic processing is easy to control the molecular orientation in the high elastic state, and the molecular orientation cannot be controlled in the viscous flow state.

                                                                                                                                           ABS Plastic Core
Extrusion is the processing of plastics in a highly elastic state that controls draw ratio, traction and speed, such as plastic wire, film, Plastic Tape Plastic Core, sheets, and sheets.

Injection molding is the processing of plastic in a viscous flow state, the molecular orientation is disordered, the magnitude of the force is different, and the freezing speed is different, resulting in different internal stresses in the product, and deformation warping occurs. Therefore, injection molding processing does not wish to have a large frozen molecular orientation.
