Pocan B1100 from LANXESS is a polybutylene terephthalate (PBT) with improved flow and high stiffness, distinguished by its resistance to elevated temperatures, chemicals, solvents, oils, fuels and cleaning fluids. The material offers good sliding properties, high strength and hardness, together with low susceptibility to stress cracking and low moisture absorption. The product is easily processed by injection molding and extrusion. Pocan® B1100 complies with RoHS 2 (Directive 2011/65/EU as amended by 2015/863) and REACH.

Advantages

• Suitable for food contact
• Resistance to chemicals, oils and solvents
• Excellent processability
• Good sliding properties and low tendency to cracking
• Low moisture absorption
• High mechanical strength
• Balance of flexibility and stiffness

Applications

Pocan B1100 is suitable for food contact, which makes it appropriate for food-processing equipment components, such as packaging machine parts that must withstand frequent exposure to cleaning and disinfecting agents.
Automotive industry: used for the production of interior and exterior parts, such as door handles, headlamp housings and other components exposed to elevated temperatures and aggressive chemicals (oils, fuels).
Production of components for consumer electronics and household appliances: for example, computer housings, controls and buttons for various household devices.

Note: Pocan® B1100 is a standard PBT (UL 94 HB), not a flame-retardant grade. For applications with UL 94 V-0 / V-2 requirements (electrical connectors, live-part housings, under-hood automotive assemblies per UL/IEC), use the LANXESS Pocan FR series: B4225, B3225, B4235.

Exablend® PBT-B3104 — unfilled hydrolysis-resistant and UV-stabilized polybutylene terephthalate from Material Wizard. An injection-molding PBT grade with hydrolytic stabilization for prolonged contact with hot water and humid environments, plus a UV/light stabilizer package for outdoor applications. Supplied in black with deep, uniform coloration and a high-gloss surface.

Exablend® PBT series — how to choose a grade

• Exablend® PBT-B3104 — base unfilled, hydrolysis-/UV-stabilized, black (this card)
• Exablend® PBT GF30-W3201 — 30 % glass-filled, self-extinguishing UL 94 V-0 (for electrical engineering)
• Made to order: grades with GF15/GF25/GF45, FR segment V-0 at <1.5 mm, grades for laser welding and metallization

What hydrolytic and UV stabilization provide

• Hydrolytic stability — extends part service life in hot water and steam-saturated environments to 5+ years (standard unstabilized PBT degrades within 6–12 months).
• UV stability — retention of color and mechanical properties after 1000+ h of QUV exposure (ASTM G154); suitable for exterior parts under direct sunlight.
• Deep black color — with a UV-resistant carbon black pigment guaranteeing color stability without “graying” after 2-3 years outdoors.

Advantages

• Low water absorption (0.3–0.4 %) and high dimensional stability in humid environments
• Good stiffness and strength for a base unreinforced PBT grade
• Excellent surface gloss of the finished part without post-processing
• Excellent chemical resistance to oils, gasoline, dilute acids and alkalis, glycols
• Low thermal expansion (CTE ~80×10⁻⁶ K⁻¹) — dimensional stability over a wide temperature range of -40 … +120 °C
• Good electrical insulation and low dielectric losses
• Property stability after repeated reprocessing of production offcuts (up to 25 % regrind)
• Compliance with RoHS 2 (2011/65/EU + 2015/863), REACH SVHC compliant

Limitations — honestly

• Not for V-0 / V-2 applications. The base grade is rated UL 94 HB — for the FR segment use Exablend® PBT GF30-W3201 or special FR grades (made to order).
• Brittleness at low temperatures (-40 °C and below) — impact-modified PBT or a PBT/PET blend is recommended for cold climate zones.
• Low impact strength without a modifier (~3-5 kJ/m² Charpy notched) — not for parts under impact loads.
• Requires drying before processing: 120 °C, 3-4 h to <0.02 % — otherwise visible surface defects and molecular weight loss in the melt (acetaldehyde-related).
• Color — black only in the base formulation (other colors require separate grades with verification of the pigment’s UV stability).
• HDT/A (1.8 MPa) ~55-60 °C — performs under load only at moderate temperatures; designs for hot liquids must account for creep.

Target applications

Automotive (exterior parts): exterior sensor housings, decorative trim components, rear-view mirror holders, headlamp washer housings, exterior fasteners.

Electrical engineering (without FR requirements): connector housings, mounting brackets, relay box components, low-power transformer housings.

Plumbing and fittings: mixer tap bodies (without contact with the water flow), decorative plumbing trims, shower system components (where EU 10/2011 is not required).

Household appliances: exterior vacuum cleaner parts, garden equipment components (trimmers, lawn mowers), brackets for air conditioners and heat pumps.

Outdoor lighting: outdoor luminaire housings, street lighting mounting components, mounting bases for solar modules.

A PBT-based compound. Heat-stabilized, hydrolysis-resistant, light-stabilized and UV-stabilized. Bright white color.

A well-balanced material with excellent gloss, low moisture absorption and stable properties under a variety of environmental conditions.

Advantages

• bright white color
• higher strength than ABS plastic
• no warpage and dimensional stability
• low price
• a circular economy product with minimal CO2 emissions

Applications

A material with a wide range of applications. Its benchmark white brightness, unattainable for polyamide and ABS plastic, makes Exablend W3100 suitable for molding high-quality hardware. It can be used instead of polyamide as a more modern replacement and does not cause warpage or sink marks thanks to its shrinkage anisotropy.
