Dow discontinues polymer brand

Dow Chemical is discontinuing its line of Questra crystalline polymers. Questra, a syndiotactic polystyrene with high heat and moisture resistance, was introduced by the company in 1997. The polymer was targeted to compete with PBT, high-temperature nylons and LCPs in automotive and electronic applications. Dow said it is discontinuing the line because of lower than expected growth.
"Questra polymers found success in a number of niche applications, but didn’t experience the broad market penetration that was anticipated," said Scott Moore, product manager with Dow’s plastic business. "Based on this narrow market position, Dow determined that the product did not provide the best possible strategic fit for future growth."
Dow will begin retro-fitting its Questra production facility in Germany for alternative use. The company said it will work with customers to find substitute materials.
