We're shiping this PBT with 25% glass fiber reinforcement—it's a solid option for electronics housings and automotive under-hood parts where heat resistance and dimensional stability matter, CAS 26062-94-2 and the formula is [(CH2)4OOC6H4COO]n, though you probably already know that. Typical tensile strength sits around 130 MPa with the glass fill, and the melting point is about 225°C, which is why it works for injection molding or extrusion without warping issues in most cases.
Most buyers in the US and EU go with the 15-30% glass content for connector bodies and relay bases—actually, the 25% is the sweet spot for balancing stiffness and flow. It's not great for transparent parts because the glass fibers kill clarity, but for structural brackets or fan blades, it's better than unfilled PBT for creep resistance.
We've got the ISO and GRS certs on file, so compliance with EU REACH and US TSCA is straightforward—import docs like the SDS and COA (HPLC tested) are included with every shipment. The MOQ is 1 ton, and packaging is standerd 25kg bags on pallets, though we can do custom labeling if you need it for your inventory system.
Color is customizable, but the natural is a light tan from the glass fibers (usually 2-4 weeks lead time for custom colors). One thing buyers don't always ask about—the recycled grade is about 10-15% cheaper but has slightly lower impact strength, so for automotive interior clips, it's fine, but for structural load-bearing parts, stick with virgin.
Basically, we supply this regularly to UK and EU injection molders—shipping from our warhouse takes about 20 days or so via sea freight, and we handle teh customs clearance paperwork. The 25% glass content is what we keep in stock most often, but we can do 15% or 30% depending on your batch requirement.
Anyway, if you're running high-volume production, the 1-ton MOQ shouldn't be an issue—we've had customers order 5 tons at once for a single automotive project. Just confirm lead time before you schedule, as we sometimes have a 3-week backlog during peak seasons.
The glass fiber content is fully customizable between 15% and 50%. So yes, we can do 30% or 40% — just let us know your target specs when you place the order.
We are ISO and GRS certified. We can provide copies of the certificates and also share test reports for each batch — just request them with your order.
We can add flame retardant, conductive, or other carriers to the PBT base. So if you need FR or conductive properties, we can formulate that — just specify the carrier type and content.
MOQ is 1 ton for custom colors, same as standard. Lead time typically runs 2-3 weeks after color confirmation, since we need to adjust the masterbatch and run a small test batch first.
Yes, they work great for injection molding thin-wall electronics parts. We have injection grade available, and the 25% glass fill gives good stiffness and heat resistance for enclosures. If you need better flow, we can adjust the additive package.
