Rohm and Haas Co. has developed a family of several impact modifiers for vinyl window profiles.
The Philadelphia-based company said the new products enable processors to customize their PVC applications for specific performance. One modifier can't do all jobs and processors don't all value the same features, Rohm and Haas said.
The new modifiers provide a wider process window based on melt temperature, which can save money and resources, according to the company. Among the new products are Paraloid KM-4400 and KM-5450, each with a different balance of lowest modifier loading, Izod impact efficiency and low temperature impact resistance.
