TPX adhesive blocking release film was developed by Shuishui Company, which used a casting process to extrude a five layer composite film of Mitsui Company's MX002 TPX adhesive release film and Sumitomo's VLDPE, with the outer two layers of TPX and the middle layer of PE film. Mainly used for laminating FPC flexible circuit boards, TPX adhesive release film has good temperature resistance, filling and separation properties, effectively improving the qualification rate of FPC flexible circuit boards.

Main performance advantages:

1. Prevent mutual transfer printing between FPC products.

2. Reduce operational procedures and improve work efficiency.

3. Control the overflow of solder pads and gold fingers. (Can be controlled below 2mil)

4. The product is free of silicone oil and plasticizers to prevent secondary pollution of FPC.

5. High temperature resistance, with a melting point above 235 ℃.

6. Prevent static electricity generation and improve product performance.

7. Halogen-free compliance with environmental requirements.

8. Chemical resistance, low water absorption.

9. Prevent high-precision FPC from being improperly pressed and control foaming.

Compared to a single multi-layer film, it can prevent operational errors.

Applicable scope

1. It can be used for flexible printed circuit substrates and hard bent circuit substrates.

2. Suitable for AMC (compliant material) is a composite material with mechanical strength and heat resistance. OPULENT can be used in the AMC manufacturing process and can be used as a demolding film for fiber cloth, carbon fiber, and epoxy resin curing processing

3. Can be used for sealing semiconductors: With the advancement of IT technology, many semiconductors have been successively introduced, and OPULENT can also be sealed with heat hardening resin and used as a demolding film during curing

4. OPULENT applications that play an important role in the development of technology

5. When manufacturing leading technology component materials such as display component materials and solar cell component materials, high-performance rubber sheets can be used as film release films or separation films for various industrial fields that require both release and heat resistance.
