Aokai PTFE dɔn tɛst krep bihayvya akɔdin to tawzin awa. Dis atikul de ɛksplen aw dɛn de evalyu krip, aw di adeziv layt ɛn sabstret ɛvri wan de kɔntribyut, ɛn us tep kɔnstrɔkshɔn dɛn de rɛsist krip di bɛst.

Wetin Na Krip insay PTFE Tep – Tu Dimɛnshɔn

Krip essentially de rifer to di viscoelastic rispכns fכ di mεtirial dεm. di adhesive layεr εn sabstεrayt de fכnshכn via difrεnt mεkanism dεm, yet dεn tu drastikli afekt כvala difכmeshכn rεsistεns.
