The higher the molecular weight of resin, the higher the mechanical properties, cold resistance, and thermal stability, but the processing temperature is also high, and molding is difficult; Low molecular weight is the opposite.
Vinyl tape, usually is PVC film as the base material, coated with a layer of rubber pressure-sensitive adhesive. Polyvinyl chloride film (PVC film) has electrical insulation performance, flame retardant, weather resistance, and other characteristics, rubber pressure-sensitive adhesive with initial adhesion and bond strength, suitable for all kinds of wire and cable insulation winding, at the same time can provide mechanical protection, acid and alkali resistance, weather resistance and other properties.
PVC (polyvinyl chloride) is one of the main varieties of general plastics, with the advantages of low price, good insulation, and corrosion resistance. The physical and mechanical properties of PVC depend on the molecular weight of the resin, plasticizer, and filler content.
Vinyl tape is made of soft polyvinyl chloride (PVC) film as the base material, coated with rubber pressure-sensitive adhesive, with good insulation, flame resistance, voltage resistance, cold resistance, and other characteristics, suitable for automobile wiring, wire winding, insulation protection, etc. Polyester electrical tape, also known as Myra tape, is made of polyester film and solvent-based pressure-sensitive adhesive, high tensile strength, and high-temperature resistance, used in the manufacture of various transformers.
1. Applications such as Wire harness bundling and protection
2. Electronic parts insulation & protection
3. Building or construction industry
4. General purpose like patching, sealing, repair, holding, etc.
The higher the molecular weight of resin, the higher the mechanical properties, cold resistance, and thermal stability, but the processing temperature is also high, and molding is difficult; Low molecular weight is the opposite.
With the increase of filler content, the tensile strength decreases. Therefore, add a large number of plasticizers, and PVC electrical insulation tape material soft, from the shape of good.
In addition, PVC electrical insulation tape according to the application requirements, red, yellow, blue, white, green, black, purple, orange and other colors, can be used for various occasions of insulation and color identification.
