Thermoplastic Polyesters - PBT
Polybutylene terephthalate, PBT, is a semi-crystalline engineering thermoplastic resin that has gained wide acceptance since its commercialization in the early 1970's.
Unreinforced grades offer performance typical of a crystalline polymer, combining good strength and stiffness with low moisture absorption, exceptional thermal stability, excellent electrical insulation properties, outstanding dimensional stability and resistance to the effects of a wide range of chemicals, solvents, and oils.
A wide range of reinforced and modified grades offer opportunities to
tailor performance to meet specific application demands. Formulations based on PBT alone,
or alloyed with PET or other polymers, are available, all exhibiting very easy processing
characteristics, and offering cost-effective solutions to application demands in every
end-use category. Many grades are available in an intermediate molecular weight base
resin - designated PBT200 - for applications where toughness and ductility are critical.
| Unreinforced Description |
PBT100L High molecular weight grade, for maximum
toughness and ductility.
(Add to Cart) |
PBT200L Intermediate viscosity,
combining toughness and good processability.
(Add to Cart) |
PBT500L General purpose injection
molding grade, lubricated for easy part ejection from the mold.
(Add to Cart) |
PBT800L High flow injection molding
grade for easiest fill of thin-section parts or multi-cavity tools.
(Add to Cart) |
PBT200STL Intermediate viscosity
formulation, impact modified to exhibit "super-tough" performance.
(Add to Cart) |
| Reinforced with Glass Fiber |
PBT500G15L A family of compounds
reinforced with 15%, 30% and 40% glass fiber to offer a choice of
(Add to Cart)PBT500G30L
strength, stiffness and toughness, satisfying the requirements of a wide range of
(Add to Cart)
PBT500G40L applications. Each compound exhibits the easy molding and fast
cycling characteristics typical of glass fiber reinforced PBT.
(Add to Cart) |
PBT200G30TL Based on the intermediate
viscosity base resin, this impact modified compound exhibits significantly improved
toughness and ductility while still maintaining excellent strength and rigidity.
(Add to Cart) |
| Reinforced with Mineral/Glass and Mineral
|
| With 40% reinforcement, these formulations
exhibit outstanding rigidity, maintained PBT500MG40L especially at high
temperatures. PBT200M40L offers best resistance to warpage or sinking
PBT500M40L in large area, ribbed, or complex parts; PBT200MG40L adds the
strength and rigidity of the glass fiber reinforced product to the control of warpage of
the mineral filled formulation.
(Add to Cart) |
| Glass Fiber Reinforced, Flame Retarded |
| A family of formulations reinforced with 10%,
15%, and 30% glass fiber, flame retarded to PBT500G10L FR comply with the V-0*
requirements of Underwriters' Laboratories Standard UL94 at
PBT500G15L FR sections as thin as 0.030 inches. This choice of reinforcement
provides a wide range of PBT500G30L FR strength, toughness, flexibility or rigidity
characteristics to satisfy the requirements of a broad range of applications in the
electrical, electronics, communications and appliances industries where UL 94 V-0
characteristics are necessary.
(Add to Cart) |
| PBT Alloys, Reinforced |
| PBET500G15L These formulations exhibit
mechanical property characteristics generally similar to their PBT PBET500G30L
counterparts, but are of special interest when outstanding surface gloss in the molded
PBET500G40L part is required.
(Add to Cart) |
| PBT91G30L Alloys developed to provide
significantly reduced warpage in large area or complex PBT82G30L shape parts,
combined with improved practical toughness.
