Isophthalic acid is primarily used in producing polyester resins for fiberglass-reinforced plastics (e.g., boats, pipes). Isophthalic acid CAS 121-91-5 also used in polyester fibers/films to enhance heat and chemical resistance, and in high-performance coatings for durability.
Additionally, Isophthalic acid CAS 121-91-5 serves as a building block for specialty polymers in electronics and aerospace.
Packed in 25 kg per drum or based on customers' requirements.
1. Container: Store in tightly sealed, dry containers (e.g., fiber drums, plastic bags with moisture barriers) to prevent absorption of moisture, Isophthalic acid CAS 121-91-5 can cause caking.
2. Environment: Keep Isophthalic acid in a cool, well-ventilated area away from direct sunlight and heat sources. IPA is stable at room temperature, but excessive heat is unnecessary.
3. Incompatibilities: Avoid contact with strong oxidizing agents, strong bases, or strong reducing agents, as Isophthalic acid CAS 121-91-5 may react (e.g., neutralization with bases).
4. Separation: Store Isophthalic acid separately from food, feed, or incompatible chemicals, and label containers clearly to avoid confusion.
