- Toray developed a new TORAYFAN® OPP film with heat resistance up to 160°C.
- The film reduces heat distortion to one-tenth of standard OPP film at 160°C.
- It is suitable for IC substrates and carbon fiber-reinforced plastic processing.
- The film is uncoated, absorbs little moisture, and offers excellent release properties.
Introduction
Toray Industries, Inc. has developed a new type of TORAYFAN® biaxially-oriented polypropylene (OPP) film, marking a significant advancement in heat resistance for such materials. The film is designed to withstand temperatures up to 160°C, comparable to certain engineering plastics.
Technical Features
The new OPP film exhibits excellent thermal dimensional stability and release properties at high temperatures. It reduces heat distortion to about one-tenth of standard OPP films at 160°C, thanks to a high-heat-resistance polyolefin resin. Additionally, the film is uncoated and absorbs minimal moisture, making it suitable for demanding applications.
Applications
This innovative film is intended for use in IC substrate and carbon fiber-reinforced plastic prepreg processes, where it can replace fluorinated films. Its properties make it ideal for applications that cannot tolerate moisture or contamination, such as processing battery components in dry rooms or using vacuum equipment for vapor deposition and sputtering.
Conclusion
Toray's new OPP film represents a significant step forward in materials technology, offering enhanced performance for industrial applications requiring high heat resistance and stability.
