石墨片保护膜系列用于散热石墨片压延后转贴,模切制程及出货保护。
As the graphite sheet is very thin ,it is easy to be damaged in the die-cutting process. We need
protection film in machining process and shipment process.
产品特点:
Characteristic:
● 千级无尘环境生产,产品洁净度高
● 剥离力稳定,低粘性范围控制较为精确
● 对多种石墨片均有稳定优异的粘结性能
● High clean class.
● Stable peel strength,especially in low peel strength range.
● Excellent adhesion performance to different graphite sheets.
一种石墨片压延工艺
产品应用:
1.转贴保护膜 Transfer film
石墨挤压成型后,容易破损。PET硅胶转贴膜背面于石墨背面,起到运输、搬运、复卷过程承载作用
This kind of film is used in the transfer process,which is fitted on the back of graphite sheet.
2.模切制程保护膜 Die-cutting protection film
用于石墨片模切垫底及排废,保护膜精密的粘性控制可降低排废工艺带起石墨片的不良现象的风险。
This kind of film is used in the due-cutting process, as the supporting film or waste discharge film.
3.出货保护膜 Shipment protection film
出货保护膜用于石墨出货和运输保护,贴合超薄单面胶背面。
拥有优异的光学性能,无需剥离即可检查石墨表面。
This kind of film is used in shipment and carriage process,which is fitted on the back of single-sided tape.
