Glass Fibre poor chemical resistance
Problem Phenomenon
Glass Fibre product after soaking in acid-alkali solvent mechanical properties drop >30%
Cause Analysis
Glass Fibre has high affinity to specific chemicals, eroded and swelled; Glass Fibre molecular chains attacked by chemicals and broken
Solution
1) Select chemical-resistant grade; 2) slight crosslinking to reduce swelling; 3) product surface coating protection; 4) add chemical stabilizer
Key Takeaway
Poor chemical resistance is caused by Glass Fibre chemical affinity; selecting chemical-resistant grade and coating are key
