Application Guidance
Propylene Glycol 20% Inhibited is a glycol-based heat-transfer and freeze-protection fluid. Concentration sets the freeze and burst protection; the inhibitor package sets how long the system stays protected from corrosion.
- Closed-loop heat transfer and process cooling
- Data-centre and chilled-water freeze protection
- HVAC hydronic loops and glycol makeup
- Freeze and burst protection for idle or seasonal systems
必要な凍結・破裂防止性能に対して濃度を確認し、使用温度におけるエラストマーおよび金属材料との適合性を確認してください。食品または飲料水への偶発的な接触が起こり得る用途には、USPグレードまたは食品グレードのプロピレングリコールのみが適しています。インヒビター入りグレードは密閉系の熱媒体用途専用です。
Storage & Handling
- Recommended Storage
- 酸化剤から離れた冷暗所に密閉して保管すること。規定の凍結温度以下での凍結を防ぐこと。ステンレス鋼、炭素鋼、ポリエチレン又はポリプロピレン製の容器。Adjudicated
- Handling Precautions
- 耐薬品性手袋および飛沫防護ゴーグルを着用してください。高温の表面や高温のプロセス機器との接触を避けてください。インヒビターは使用中に消耗します。やみくもに補充せず、監視してください。Class-level guidance — not product-specific; the SDS controls.
- Incompatibilities
- 強酸化剤、強酸、強塩基。Adjudicated
- Shelf Life
- Consult Technical Services for product-specific shelf life
