What are the properties and uses of PVC Flex Banner?

PVC Flex Banner is based on polyvinyl chloride resin, adding auxiliary materials such as foaming agent and stabilizer, and is a closed-cell foam plastic made by kneading, ball milling, molding and foaming. In addition to the soft and hard performance of technical products, there are three types of soft, broken and calibrated.
PVC Flex Banner is made by calendering process. Calendering is to pass the heated polyvinyl chloride plastic through the gap between one or more pairs of oppositely rotating horizontal rollers, so that the material is subjected to extrusion and extension to become a certain thickness, Process for thin products of width and smooth surface. Polyvinyl chloride calendered film occupies an important position in plastic shed film. In addition, it has a wide range of applications in Yantian thatch cover, industrial packaging, electrical insulation, inflatable film products, light box advertising, engineering waterproofing, and daily necessities packaging.
The reason why PVC Flex Banner Manufacturers is so widely used is that it has the following characteristics. high tensile strength
The tensile strength of PVC Flex Banner is as high as 29MPa. In the previous sandstorms in the northwest, both the PE film and the EVA film were damaged, only the PVC Flex Banner was intact.
Good thermal insulation performance
As a covering material for agricultural greenhouses, glass has the best thermal insulation performance, followed by PVC calendering film (with strong infrared absorption ability), and PE film again. In addition, the thermal insulation performance of PVC calendered film is not much different from that of glass at night, which is extremely beneficial to promote the growth of crops.
good transparency
The PVC calendered film is extruded by the mirror roller during the molding, and the surface finish is very high, and the phenomenon of condensation water droplets is less, so the light transmittance is high, which is very beneficial to the photosynthesis of crops.
uniform thickness
Because the roller of the PVC calendered film is in the shape of a middle drum, the middle rollers cross, the lower roller has a pre-strain, and the roller surface is finely ground, so the thickness accuracy is high.
good adhesion
According to the needs of the application, the PVC calendered film can be used by high-frequency welding, thermal bonding and adhesive bonding, which is easy to use.
In addition, according to the different uses of PVC calendered film, it can be satisfied by changing the production formula and process conditions.
