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. 

Tisester^® PBT compounds with high tracking resistance make small contact distances possible condition for increasing minimization. 

Tisester^® PBT formulations can also be developed to meet specific market needs. 

Tisester^® PBT is a fully recyclable material and it can be reused after regrinding. 

The user shall always verify that the compound obtained by mixing virgin and reground material is suitable for the specific application and that its properties meet the requirements. 

Tisester^® PBT grades can be provided fully colored in customized colors with narrow color specifications colorability even in light colors.
