1,2,3,4-Butanetetracarboxylic acid (BTCA) is a perfect formaldehyde-free durable press(DP) finishing agent. It has high activity of reaction and no irritant odor. Processed by BTCA, fabrics such as cotton and silk can achieve properties including anti-cease, permanent press and keeping shape and are of high tenacity.
BTCA can be used to prepare polyimide materials. This kind of material has excellent heat resistance, acid resistance, hydrocarbon resistance and good electrical insulation properties, and can be used to prepare various functional polymer materials, such as photosensitive materials, medical polymer materials and functional polymer membrane materials. It can be used to prepare electrical insulation rings, wire coatings and electrical insulation materials.
