Pocan®

Pocan® is the trade name for our polybutylene terephthalate (PBT) and its blends.

Pocan® offers a high heat resistance, strength and hardness, as well as excellent slip properties and high abrasion resistance, good resistance to chemicals, low susceptibility to stress cracking and low moisture absorption.

Apart from the injection molding grades, there are also Pocan grades for the extrusion of semi-finished products, foils and cable sheathing, as well as non-reinforced products, and glass-fiber reinforced, glass-sphere, or mineral-filled products. Flame retardant, elastomer-modified and food-approved grades are similarly available, as are blends with ASA and PC.

Product Characteristics
Natural color
Light ivory, opaque

Colors
In addition to uncolored and black material, a series of opaque standard colors is available. Special colors are also possible.

Surface finish
High-gloss or textured, depending on mold surface

Stiffness
High, particularly GR grades, tensile modulus 1700 to 17 000 MPa

Impact and break resistance
High but notch-sensitive
elastomer-modified grades have good low-temperature impact strength

Resistance to dynamic loading
High

Stress crack resistance
Good

Heat resistance
High; depending on grade
Short-term peaks from 160 to 210 °C (GF grades to 240 °C), permanent service temperature: 90 to 140 °C

Dimensional accuracy and stability
Good but not quite on the same level as amorphous thermoplastics

Abrasion resistance
Good

Chemical resistance
Good; particularly resistant to fuels, lubricants, solvents and cleaning fluids
