Ionomers

Ionomers appear as transparent to translucent thermoplastics with exceptional clarity, toughness, and a unique combination of softness and resilience. Key features include excellent toughness even at low temperatures, superior clarity, outstanding cut and puncture resistance, good chemical resistance, and exceptional energy absorption. Ionomers excel in packaging films, golf ball covers, footwear components, and sporting goods. 

Ionomers compete with EVA and polyurethanes. The industry is trending toward developing sustainable versions with bio-based content and enhanced recyclability. Various grades exist based on the neutralizing metal ion (sodium, zinc, magnesium), acid content, and degree of neutralization, with sodium ionomers offering better clarity and strength, zinc ionomers providing enhanced flexibility and processability, and magnesium-based grades offering specific performance advantages in specialty applications requiring unique property profiles.
