Aokai PTFE debuted ya zuru ngwaahịa lineup na APFE Shanghai 2026 (Booth 6T602, Ụlọ Nzukọ 6). Ngwaahịa egosipụtara na-agụnye teepu PTFE nke fiberglass gbasiri ike, ihe nkiri PTFE dị ọcha, akara ule mgbochi static, na eriri ebu oke okpomọkụ - na-ekpuchi nhazi nri, PV lamination, batrị lithium, ngwa elektrọn, na nkwakọ ngwaahịa. Ihe ngosi a na-aga na June 26. Ngwaahịa niile na-akwado nkọwa omenala.

PTFE elu ọgwụgwọ maka bonding adhesion eji abụọ isi ụzọ: elu-okpomọkụ agbaze (elu ihu igwe eguzogide, 9.5 MPa ike na njikọ njikọ, ma tọhapụrụ toxic gas) na sodium-naphthalene etching (5 MPa ozugbo adhesion, warara 24-48 hour window, ize ndụ n'efu).
