How to choose the appropriate material and thickness<br/>There are a number of factors to consider when choosing the right film veneer material and thickness. Here are some key guidelines:<br/><br/>1. Material selection:<br/>PVC material: The price of PVC film material is low, suitable for the production of civilian popular products, in order to reduce production costs. PVC material has good ductility and is suitable for making decorative panels. However, it should be noted that PVC materials may not perform as well as PC materials in some properties.<br/>PC materials: PC materials generally have better optical properties, weather resistance and chemical resistance. If the product requires prolonged exposure to the outdoors or exposure to chemicals, PC materials may be a better choice.<br/>P E T material: P E T material is used in some special occasions, such as insulation, rebound, solvent resistance, etc.<br/><br/>2, thickness selection:<br/>Film panel thickness: For film panels, a thickness between 0.125 and 0.15 mm is usually appropriate. Too thin film may not rebound, contact separation is not sensitive; And too thick may lead to slow reaction, increase the operation force.<br/>Application scenario: If the bond body is large, such as the diagonal length or the diameter of the circular bond is greater than 12 mm, it may be more appropriate to choose a thicker film (such as 0.15 mm), as it provides better recoil and less tendency to relax. For the circuit contact bubbling film, generally use 0.125 mm thick film.<br/><br/>3. Other considerations:<br/>Appearance requirements: Ensure that the surface of the film surface is smooth and the luster is consistent, and there is no mechanical damage, scratches, inclusions and color spots and other surface defects.<br/>Chemical resistance: The panel layer should be resistant to common chemicals, such as alcohols, ethers, mineral oils, etc.<br/>Weather resistance: the film veneer needs to maintain stable performance under certain natural environmental conditions, without deformation, cracking, aging and color change.<br/>Dimensional stability: The film surface should maintain dimensional stability within a certain temperature range to avoid performance problems caused by temperature changes.<br/>To sum up, the selection of the appropriate film veneer material and thickness needs to be balanced according to the specific application scenario, budget and performance requirements. It is recommended to fully communicate with the supplier before purchasing, understand the performance characteristics of various materials, and consider sample testing to verify their suitability.
