Description

Poly(2,6-dimethyl-1,4-phenylene oxide) PPO is amorphous and relatively nonpolar. It offers low moisture absorption, good strength, and high heat-resistance. Excellent compatibility with other polymers for blending. Pure PPO resin cannot be easily processed at temperatures above its glass transition temperature because of poor melt flow.

Application areas

Automotive, business machine, and electrical/electronics industries. PPO is mainly used to manufacture blends with high-impact polystyrene (HIPS). PPO/nylon, PPO/PBT, and PPO/polyolefin blends are also available on the market. PPO based materials ranking first in terms of total consumption among blends based on engineering resins such as nylon, polycarbonate (PC), polyacetal, and reinforced terephthalate polyesters (PET and PBT).
