Tensile strength and elongation at break are very important parameters in mechanical testing of plastic film materials, which respectively reflect the deformation and brittleness of the plastic film material during stretching. Plastic film test method include ISO 527-3, GB/T 1040.3, ASTM D882, etc.
Different types of plastic film, with different properties and states of burning flames. The common plastic film burning phenomenon refers to igniting a small piece of film with fire, observing the change of the nature and state, the difficulty of burning, the presence or absence of spontaneous combustion (whether the plastic film continues to burn after leaving the flame), odor, flame and smoke color phenomena after combustion, such as the color and state of the residue after combustion.
With the continuous emergence of various new materials, new equipment and new processes, plastic TPU film is developing in the direction of variety, specialization and multi-functional composite films. The most commonly used method for surface treatment of plastic TPU film is corona treatment.
PVC plastic material is one of the five general-purpose synthetic plastics, Due to the poor cold resistance and low temperature impact resistance of PVC, the application of PVC plastic materials is limited in some field. The brittle temperature is an index for the cold resistance of soft PVC film
PET film is a kind of common plastic film material in electronics, adhesives, die-cutting, packaging and other industries. How to identify PET polyethylene film, from other plastic foil material?
