聚四氟乙烯管材
PTFE Tubing
【 特 征 Features】
|
|
聚四氟乙烯管材選用懸浮聚合聚四氟乙烯樹脂經(jīng)柱塞擠壓加工制成。在已知塑料中聚四氟乙烯具有最好的耐化學(xué)腐蝕性能及介電性能。
PTFE tubing is manufactured by ramextruding method with PTFE granular resin. PTFE is the most chemical-resistant plastic of all know plastic.
It has the best electrical properties of plastics.
