ELIX ® 300 resins ‐ impact modified styrene maleic anhydride terpolymers ‐ allow for improvements in practical heat distortion resistance of PVC to temperatures over 100°C whilst adding impact resistance and maintaining its chemical resistance and fire retardancy. This paper describes what is meant by practical heat distortion resistance and how the semi‐compatible nature of PVC/ELIX ® 300 blends helps to meet higher in‐use temperature requirements. Main properties of PVC/ELIX ® 300 blends as a function of concentration and K‐value of the PVC, considerations concerning formulations and the influence of compounding techniques on morphology and properties are discussed and some practical application examples are given.
