TPUの白化現象をどのように解決しますか？
How to solve the TPU whitening phenomenon?
テントのTPUドアが白化する原因は何ですか？
テントのTPUドアが白化する原因は、主に以下の要因によるものです。
1. 紫外線（UV）照射
長時間の直射日光、特に強い紫外線にさらされると、TPU素材の分子構造が破壊され、白化・黄変・脆化することがあります。
2. 温湿度の変化
高温曝露：高温環境では、TPU内部の可塑剤が揮発または分解し、透明度が低下して白斑が現れることがあります。
低温環境：寒冷環境では、TPUが硬化し、分子構造が変化することで白化することがあります。
湿気の影響：湿度が高いと、TPUが水分を吸収し、微小な水分子が蓄積されて白く見えることがあります。
3. 化学反応
洗剤の影響：アルコールや強酸・強アルカリを含む洗剤を使用すると、TPUが化学反応を起こし、表面構造が損傷し白化することがあります。
大気中の汚染物質：工業排気ガスや酸性雨などの影響で、TPUの透明度が低下することがあります。
4. 物理的なストレスや損傷
頻繁な折り曲げや引っ張り、摩擦によって、TPUの表面構造が変化し、白化することがあります。
長期間丸めて保管すると、TPU表面に折り目がつき、一部が白化することがあります。
予防と対策
✅ 紫外線対策：UVカットコーティングが施されたTPU素材を選ぶか、テントの外側にシェードを追加し、直射日光を避ける。
✅ 化学薬品を避ける：洗浄にはぬるま湯と中性洗剤を使用し、アルコールや強い化学薬品を避ける。
✅ 適切な保管：TPUドアを乾燥した状態で保ち、長期間折りたたんだままにせず、柔らかい布で包んで摩擦を防ぐ。
✅ 低温修復：軽度の白化の場合は、ドライヤーの低温モードで温めることで、TPUの柔軟性と透明度を回復させる（高温で加熱しすぎないよう注意）。
TPU白化現象の解決方法
1. アルコールを含まないウェットティッシュで表面の汚れを拭き取る。
2. 乾燥機能付きの洗濯機に入れ、低温または常温で10～15分乾燥させる。
（※ S450のようなテント本体は乾燥機に入れないでください。シームテープが剥がれる可能性があります。）
3. TPUの白化現象が大幅に軽減されていることが確認できます。
注意点：BLACK DRAGONは、白化現象を軽減するための方法として本手順を提案しておりますが、結果についての責任は負いかねます。 乾燥機の性能や環境によって効果が異なるため、ご了承ください。
English Version:
The whitening phenomenon of TPU tent doors is mainly caused by the following factors:
1. UV Exposure
Prolonged exposure to direct sunlight, especially strong UV rays, can break down the molecular structure of TPU, leading to whitening, yellowing, or brittleness.
2. Temperature and Humidity Changes
High Temperature Exposure: In hot environments, plasticizers within TPU may evaporate or decompose, reducing transparency and causing white spots.
Cold Environments: TPU can harden in cold temperatures, altering its molecular structure and leading to whitening.
Moisture Absorption: High humidity can cause TPU to absorb water, creating tiny water molecule deposits that appear as a white haze.
3. Chemical Reactions
Effect of Cleaning Agents: Using alcohol-based, strong acidic, or alkaline cleaners can cause chemical reactions that damage TPU's surface, resulting in whitening.
Airborne Pollutants: Industrial gases and acid rain may also react with TPU, reducing its transparency.
4. Physical Stress and Damage
Frequent folding, stretching, or friction can alter TPU’s microstructure, causing whitening.
Long-term rolled-up storage may create creases in the TPU surface, leading to localized whitening.
Prevention and Solutions
✅ UV Protection: Choose TPU materials with UV-resistant coatings or use an external shade to reduce direct sunlight exposure.
✅ Avoid Harsh Chemicals: Clean with warm water and mild detergent, avoiding alcohol-based or strong chemical cleaners.
✅ Proper Storage: Keep TPU doors dry, avoid prolonged folding, and wrap them in soft cloth to prevent friction damage.
✅ Low-Temperature Restoration: For minor whitening, gently warm the TPU with a hairdryer on low heat to restore flexibility and transparency (avoid excessive heat).

Solution for TPU Whitening
1. Wipe off surface stains with alcohol-free wet wipes.
2. Place it in a washing machine with a drying function and dry at low or normal temperature for 10–15 minutes.
(Note: Do not put tent bodies like the S450 into the dryer, as it may cause seam tape to peel off.)
3. You will see a significant reduction in TPU whitening.
Precautions：
BLACK DRAGON recommends this method as a way to reduce TPU whitening; however, we are not responsible for the results. The effectiveness may vary depending on the drying machine and conditions. Thank you for your understanding.
