PTFE熱収縮チューブ

PTFE熱収縮チューブ

材料紹介

PTFE熱収縮チューブ ポリテトラフルオロエチレン（PTFE）製の高性能チューブで,優れた熱絶縁性,耐薬品性,耐電気性を備えています。加熱すると収縮し,電線,ケーブル,部品にぴったりと密着して保護します。非粘着性で知られるPTFE熱収縮チューブは,極端な温度（-200℃～+260℃）,腐食,紫外線にも耐性があります。航空宇宙,医療,産業用途に最適で,過酷な環境下でも耐久性を確保します。摩擦係数が低く,絶縁耐力も高いため,繊細な電子機器の組み立てに最適です。

製品の特徴

PTFE（ポリテトラフルオロエチレン）熱収縮チューブは,要求の厳しい用途向けの高性能ソリューションです。以下に,その優れた特性とそれを裏付ける技術データを示します。
1. 極端な温度耐性： -200℃～+260℃（-328°F～+500°F）の連続使用温度範囲において,PTFE熱収縮チューブは従来のポリマーでは構造的完全性が損なわれるような状況でも,その完全性を維持します。また,300℃（572°F）までの断続的な高温にも劣化することなく耐えます。
2. 化学的不活性： demonstrating <1% weight change after 168-hour immersion in concentrated acids （h2so4 98%), bases （naoh 50%), and solvents （acetone), ptfe offers superior chemical resistance compared to fep or pvc alternatives.
3. low friction coefficient: with a dynamic coefficient of friction as low as 0.04-0.10 （astm d1894), PTFE熱収縮チューブ provides excellent non-stick properties, reducing mechanical wear in dynamic applications.
4. high dielectric strength: the material exhibits dielectric breakdown voltage >20 kv/mm （astm d149) with volume resistivity >1018 Ω·cm, making it ideal for high-voltage insulation （up to 600v rated).
5. 精密収縮率： 2:1および4:1の収縮率で提供され,寸法公差は±5%（mil-dtl-23053/4規格）であり,収縮後の回復率と肉厚の均一性を保証します。
6. 超低ガス放出： 総質量損失量（tml） <0.1% and collected volatile condensable materials （cvcm) <0.01% （nasa sp-r-0022a), meeting stringent requirements for aerospace and vacuum applications.
