25g / in MLCC PET Silicone Release Film Cleanroom-grade Manufacturing
››› Product Introduction
This product is used as a base material of high flatness,high temperature resistance PET, coated on the surface of the thin layer of release substance MLCC formulations. Mainly used in MLCC tape coating.
››› Product Features
1.Producing in the 1000-level clean environment, with high cleanness;
2.The coating is uniform and the film surface is flat with minimal tolerance, making the subsequent process easy to process;
3.High residual adhesion rate (≥85%), no performance impact on the bonding material, non-polluting;
4.Precision for Miniaturized MLCCs: Supports ultra-thin ceramic layers (down to 1μm) required for 300–1,000-layer capacitors in 5G and automotive electronics.
5.Defect-Free Production: Free of pinholes, streaks, or foreign particles to meet stringent quality standards for high-reliability applications.
››› Product Structure
››› Product Use
1.Post-Processing & Recycling
Punching Protection: Used as a buffer between MLCC stacks and molds during punching to prevent mechanical damage.
Reusability: Companies like TDK and Murata have implemented recycling programs for PET release films to reduce costs and environmental impact.
2.Material & Structural Properties
High-Quality PET Base Film: Made from bidirectional-stretched polyester (BOPET), offering superior mechanical strength, rigidity, and tear resistance for stable handling during high-speed production.
Silicone Coating: Uniform organic silicone coating ensures controlled release force and residue-free peeling, critical for multi-layer ceramic stacking.
››› Product Packaging
1.Products are generally used by cardboard tray, nude tray packaging;
2.All cartons of products have certificate, packing list, each tray should have a list of products;
3.Our products can also be packaged according to the requirements of the user agreement.
