Tisester® PBT

Tisester® PBT is the registered trade mark for Polybutylene Terephthalate compounds produced by Tisan. Polybutylene Terephtalate (PBT), partially crystalline saturated polyester. PBT has excellent resistance to a broad range of chemicals at room temperature, including aliphatic hydrocarbons, gasoline, carbon tetrachloride, perchloroethylene, oils, fats, alcohols, glycols, esters, ethers and dilute acids and bases. They are attacked by strong bases. Tisester® PBT is crystalline, high molecular weight polymer that has an excellent balance of properties and processing characteristics. Because the material crystallizes rapidly, mold cycles are short and molding temperatures can be lower than for many engineering plastics. Tisester® PBT is excellent for its very good dimensional stability, low water absorption. In some areas, Tisester® PBT is replacing other crystalline thermoplastics such as polypropylene, nylon and acetal because of the need for improved performance.
