Product Descriptions
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 possibles condition for increasing minimization.
Tisester® PBT formulations can also be developed to meet specific market needs.
Tisester® PBT is a fully recycable 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.
Main specifications
Modification of PBT by compounding with glass fiber, mineral fillers and modifiers produces a substantial change in the properties of the base material and gives to compositions based on Tisester® PBT the following properties;
Excellent stiffness and hardness, good mechanical strength, good creep and fatigue resistance, very good thermal stability, high wear resistance and low friction, good dimensional stability, very good chemical resistance, excellent flow and processing properties, low water absorption, very good surface finish, no tendency to form stress cracks, high tracing resistance, high good sliding properties, excellent heat ageing behavior. Flame retardant compound with halogen and halogen free, UL94 V-2 or V-0 classifications (UL approved grades), glow wire flammability index, glow wire ignition behavior (no flame), low smoke density.
Fillers / reinforcements / modifiers
Glass fibers-glass beads-carbon fibers-mineral fillers are available with varying contents in different combinations. And also filled materials containing PTFE available with appropriately low friction and improved wear. Heat stabilizers-hydrolysis stabilizers-lubricants-UV stabilizers, electrical conductive etc. are being used in non-reinforced and reinforced grades to increase specific material properties.
