CAS: 121-91-5
Isophthalic acid; a well used aromatic dicarboxylic acid as it boosts the performance of high-performance polymers It strikes some resemblance with other terephthalic acid derivatives in terms a bit more compatibility or considerably superior thermal stability resulting it fundamental for the production of durable and hard materials especially for the production of plastic (and rubber) products, resistance to heat and chemicals is paramount in which this property is profitable. Isophthalic acid is a great enabler of product life and performance making it very essential to industry driven performance durability.
