If you're looking up Toray carbon fiber and also wondering whether rubber is a plastic, here's the short answer up front: Toray T1000G is a real, high-performance fiber with a published typical tensile strength of 6,370 MPa and a tensile modulus of 294 GPa, but strength alone doesn't make it the right material. You also need to know which Toray business unit to call, what resin system you need, and that rubber is not plastic. I've been buying materials for a composite parts shop since 2021, and in that time, the biggest sourcing mistakes I've seen weren't about fiber grade—they were about talking to the wrong people and treating material categories like they're interchangeable.
Here's the starting place: Toray's carbon fiber business and Toray's plastics business are separate sales channels. You don't order T1000 from a film supplier, and you don't ask the resin desk for prepreg. That may sound obvious, but you'd be surprised how many purchase orders get delayed because someone called Toray Plastics and asked for carbon fiber.
Who I am and why this is practical
I'm not a materials engineer. I'm an office administrator for a 160-person company that makes composite parts and industrial components. I manage approximately $1.4 million in raw material purchases across 14 vendors, and I report to both operations and finance. My job is to turn engineering requirements into purchase orders that arrive on time, with the right certificates, and without expensive surprises.
It took me four years and a lot of order errors to understand that brand names and product categories are not as clear as they look on a website. When I took over purchasing in 2021, I assumed one Toray account would cover everything. In reality, the carbon fiber representative and the plastics representative are different people, sometimes in different states, with different catalogs. That distinction matters more than most spec sheets.
Toray T1000 Carbon Fiber: Tensile Strength and Modulus
Let's get the numbers out, but take this with a grain of salt because they're typical published values, not guaranteed lot limits. As of early 2025, Toray's publicly available product data for fiber grades shows:
- T300: tensile strength 3,530 MPa, tensile modulus 230 GPa
- T800S: tensile strength 5,880 MPa, tensile modulus 294 GPa
- T1000G: tensile strength 6,370 MPa, tensile modulus 294 GPa
- T1100G: tensile strength 7,000 MPa, tensile modulus 324 GPa
The counterintuitive part is in the middle: T1000G and T800S have the same tensile modulus. If your part is stiffness-limited, spending the extra money on T1000G may not buy you anything. In a 2024 prototype, our engineering team asked for T1000G because they wanted the strongest fiber. The measured stiffness improvement over T800S was marginal. The real fix was a different ply layup and a higher modulus M-series fiber, but we didn't realize that until after the first test round.
Also, carbon fiber rarely works alone. Most structural applications use it with a matrix, usually an epoxy resin. If you type 'apoxy resin' into a search box, the standard term is epoxy resin—and it's not a minor detail. The resin system controls cure behavior, heat resistance, and impact performance. The fiber and resin have to be specified together. I've bought carbon fiber enough times to know that the phrase doesn't include resin or prepreg unless the purchase order says so.
Typical property values are not minimum or guaranteed values. Always request the mill certificate for the specific lot.
Toray Plastics Locations: Don't Call the Wrong Desk
When someone searches Toray plastics locations, they often expect a single factory or distributor list. My experience is different. The Toray organization sells materials through separate business lines:
- Toray Plastics (America)—based in Rhode Island in our vendor file—mainly handles films and packaging products, not carbon fiber.
- Toray Resin is the brand name for engineering resins and compounds, including PE, PP, ABS, PA, and PC products. Those are typically sold through compounders and distributors.
- Toray's carbon fiber operation has its own sales and technical support, often through Toray Composite Materials America or similar entities depending on your region.
Toray's internal structure has shifted before, and I'm not 100% sure of the current legal entity names, so always check the website. The separation between film, resin, and carbon fiber sales has been consistent, though. For a buyer, the practical rule is: identify the product family before you search for locations. In 2023, I got a quote for Toray PP from a film supplier and almost ordered a film product for an injection-molding project. The product was technically Toray polypropylene, but it was not a molding grade. A quick call to the resin distributor fixed it, but it cost us a week and a few gray hairs.
Epoxy Resin, Polyethylene Fiber, and the Rubber Question
Epoxy resin
Epoxy resin is the matrix that holds carbon fiber together in many prepregs and wet-lay systems. If you're specifying a composite part, you need the fiber, the resin, and the layup schedule. Don't assume that Toray T1000 from a fiber supplier automatically includes an epoxy system. It doesn't. The resin choice affects cure cycle, operating temperature, and impact resistance. I've seen a $30,000 order error caused by assuming the supplier would include resin in the prepreg quote.
Polyethylene fiber
Polyethylene fiber is not carbon fiber. High-performance polyethylene fiber (usually UHMWPE) is strong, light, and chemical- and cut-resistant, but it has a low melting point and much lower stiffness than carbon fiber. If a drawing says polyethylene fiber, don't swap in carbon fiber without checking the application. If it says carbon fiber, don't ask for polyethylene fiber. It sounds too basic to mention, but material classification errors happen more often than you'd think.
Is rubber a plastic?
No. Rubber is an elastomer, not a plastic. Both are polymers, but a plastic typically holds its shape after molding, while rubber can deform significantly and spring back. Some thermoplastic elastomers sit on the boundary, but for practical sourcing, rubber and plastic are separate categories. This matters in purchasing because a plastic compound won't substitute for a rubber gasket, and a rubber supplier won't give you the rigidity of an ABS or polycarbonate part.
Toray's portfolio includes a lot of plastics and carbon fiber, but it doesn't claim to cover elastomers. In my opinion, that's a good sign. The vendor who says this isn't our specialty—go to a rubber-compound specialist—is more trustworthy than one who says a polymer is a polymer. I'd rather work with a specialist who knows their limits than a generalist who overpromises.
Where This Doesn't Apply
Everything above assumes engineered, material-critical applications. If you're buying commodity plastic film, a standard resin on a spot market, or a generic rubber gasket, you don't need the same due diligence. The typical values I quoted are useful for initial screening, but they are not a guarantee. For critical aerospace, automotive structural, or pressure-containing parts, work with a licensed engineer and rely on Toray's official datasheets and lot-specific test certificates.
I don't spec materials. I make sure the right material arrives with the right paperwork. That boundary is exactly why asking 'is rubber a plastic?' early is better than discovering it after a $40,000 PO is placed. And if a supplier tries to blur that boundary, I treat it as a red flag.
