Polyester Film
Polyester Film Polyester film is a film material made of polyethylene terephthalate as raw material, made into thick sheets by extrusion method and then biaxially stretched. At the same time, it is a polymer plastic film that is increasingly favored by consumers because of its excellent comprehensive properties. Since my country's current production volume and technical level still cannot meet the market demand, some parts still need to rely on imports. It is a colorless, transparent and shiny film with excellent mechanical properties, high rigidity, hardness and toughness, high puncture resistance, friction resistance, high and low temperature resistance to chemicals, oil resistance, good air tightness and fragrance retention, and is a commonly used barrier composite film base. One of the materials. However, the price of polyester film is relatively high, and its thickness is generally the outer material commonly used for retort packaging. It has better printability.
Insulation sheet Mylar sheet
Product name: Mylar sheet Product description: Mylar sheet has stable and straight dimensions and excellent tear strength, heat resistance, cold resistance, moisture resistance, water resistance, chemical corrosion resistance and super strong Insulating properties. Product Usage: Suitable for gaskets, shields, screens and protection of electronic household appliances, instruments, monitors, motors, slots, computers and peripheral equipment. Anti-static insulation, heat resistance, temperature resistance, voltage resistance, flame resistance, shielding, isolation and other properties can be used for the isolation of wires and cables, computers, laptops, printing, transformers, power supplies, small motors, and electrical insulation.
Thin film insulation sheet
Uses of film
1: High-voltage electrical equipment: motorcycle insulators. Transportation insulators. Rolled sheet insulators
2: Cable communication wires and cable packaging . Packaging of functional cables.

Variable capacitors. Flexible circuit board keyboard membrane. Insulating material flat motor. Cable wrapping. Industrial tape internal covering material. Audio film diaphragm
High temperature resistance Release Film
The absence of migration eliminates the risk of the silicone release film transferring to the material to which it is attached
The tolerance of the weight per unit area of the release film on one or both sides is very small
The base film has excellent mechanical strength and chemical properties
It has high stability under extreme weather conditions. The high temperature resistance can reach about ℃ for a long time and can reach about ℃ within an hour
br/>Long shelf life
Adhesive-type release types are divided into light peeling type, medium peeling type and heavy peeling type based on the mobility of silicon and the change in peeling force after heating. The release force and resistance can be controlled according to requirements. Thermal performance is good.
The release film has different thicknesses for customers to choose. The general application thickness/products are divided into light, medium and heavy release. Different release forces are suitable for laminating tapes or films with different viscosity.
Characteristics and uses of release films
Single-sided and double-sided release films are mainly used to evenly coat a very thin layer of release film on one or both sides of the substrate due to its superior high temperature resistance. The release film is made of an agent and has a smooth surface, even coating, no wrinkles, particles, bubbles, pinholes and other defects. The product has excellent physical properties, small thickness tolerance, and low thermal shrinkage. It is mainly used as an isolation material when processing printed circuit boards made of epoxy resin. Has high tensile strength and tear strength.
Release films are generally used to isolate sticky materials and are widely used in electronics, adhesives, printed circuit boards and other industries. Product thickness: .~. Suitable for thermal transfer printing and more suitable for die-cut gaskets, adhesive products, punching, etc. Controllable release force, high gloss, cleanliness, high residual adhesion, and good surface properties.
