Urethane Casting Materials
ABS-Like
ABS-Like Urethane is a very flexible casting material whose characteristics are comparable to ABS plastic when it comes to resisting high impact, heat, and moldability. It possesses fair mechanical strength, thermal resistance, and chemical stability and is ideally used for prototyping car parts and low-volume manufacturing of consumer items and functional models. It can be easily painted, plated, or textured for additional functionality and appearance.
- Production Lead Time: Up to 5-10 days
- Color: White, Black, Gray, Custom Colors Available
Nylon-Like
Nylon-Like Urethane mimics the features of Nylon, including wear resistance, hardness, and low friction. It must be used where strength and long-life operation are required, i.e., mechanical components, bearings, and gears. It can maintain good strength, chemical resistance, and dimensional stability, thus applied to automobile, industrial, and electronic parts. Nylon-Like urethane can easily be machined and painted to achieve additional functionality and aesthetics.
- Production Lead Time: As fast as 5-10 days
- Color: White, Black, Gray, Natural, Custom Colors Available
Polypropylene-Like
Polypropylene-Like Urethane mimics the properties of Polypropylene, offering excellent chemical resistance, flexibility, and low-cost production. This material is ideal for parts exposed to chemicals and harsh environments, such as fluid handling components, containers, and valves. It combines ease of processing with good strength and impact resistance, making it suitable for automotive, industrial, and consumer goods applications. Polypropylene-Like urethane can also be customized with various finishes for improved performance and aesthetics.
- Production Lead Time: As fast as 5-10 days
- Color: White, Black, Gray, Natural, Custom Colors Available
Rubber-Like
Rubber-Like Urethane is very flexible, has superior tear strength, and is very resiliency-resistant, and is thus justifiably deserving of use in such applications that consist of soft, flexible components. It is closer to rubber in property but is tougher and possesses superior abrasion and thus finds use in seals, gaskets, bumpers, and cushioning components. It will blend the benefits of rubber and urethane, i.e., ease of processing and long-term durability with long-term performance by industries like automobile, electronics, and consumer goods.
- Production Lead Time: 5-10 days at most
- Color: White, Black, Gray, Natural, Custom Colors Available
Polycarbonate-Like
Polycarbonate-Like Urethane imitates Polycarbonate performance, and it is characterized by high impact strength, optical clarity, and toughness. It finds maximum suitability in clarity and strength uses, including light covers, lenses, and protective casings. The material has outstanding durability and resistance to cracking, optimally suited for consumer electronics, auto components, and protective headgear. Polycarbonate-Like urethane is also easy to process and can be painted or textured for secondary functionality.
- Production Lead Time: Up to 5-10 days
- Color: Clear, White, Black, Gray, Custom Colors Available
TPE-Like
TPE-Like Urethane mimics the performance of Thermoplastic Elastomers (TPE), trading the rubbery flexibility against the processability of the plastic. It is more elastic, tougher, and abrasion-resistant and thus best suited for soft-touch grips, overmolded parts, and elastic uses. TPE-Like urethane possesses high impact strength and is moldable into complex geometries with ease, and thus proves to be a good all-around material for automotive, medical, and consumer products markets.
- Production Lead Time: As fast as 5-10 days
- Color: White, Black, Gray, Natural, Custom Colors Available
High-Temperature Urethane
High-Temperature Urethane is designed to withstand demanding heat with added heat stability and resistance. It will maintain mechanical strength and toughness when subjected to high heat conditions and is thus best used for high-performance application in the automotive, aerospace, and industrial sectors. The product will be more thermally stable, chemically resistant, and resistant to long-term reliability when exposed to heat, offering higher life of performance for critical components subject to severe heat.
- Production Lead Time: As fast as 5-10 days
- Color: White, Black, Gray, Natural, Custom Colors Available

Formioo Urethane Casting Service FAQs
We collect a lot of FAQs from our real clients, and please check out our FAQ page. For more information about Formioo Company, you can also download our company E-catalogue brochure.
Why choose urethane casting over 3D printing?
One of the greatest advantages of urethane casting over 3D printing is the material performance and quality it offers. Urethane casting uses materials that closely resemble commercial production materials, and they possess enhanced mechanical properties with greater durability. Additionally, parts made from urethane casting generally have a better fit and finish than 3D-printed parts. If you are most concerned about material functionality and a luxury appearance, then urethane casting is the technique you must utilize.
Why use urethane casting instead of injection molding?
The most important consideration in choosing injection molding versus urethane casting is volume of production. Urethane casting is an economic method for low-volume production, approximately 50 units, of production-quality product with less up-front cost of the tool than injection molding. It is therefore an ideal option for short-run production or verification of design prior to large-scale production. Many clients employ urethane casting as an in-process step to test and iterate with their designs before investing in injection molding tooling.

Formioo’s streamlined system makes it easy to receive an accurate quote and begin your polyurethane casting endeavor with confidence.
Can urethane casting be used for production-quality parts?
While urethane casting is primarily appropriate for visually appealing prototypes, it can also be used for non-mechanical end-use products such as enclosures, cases, and covers.
What happens to the silicone molds? Can I Keep Them?
Silicone molds used in the process of urethane casting are of a limited working life, and hence they can last up to around 20 cycles before breaking down. Because of this, we typically discard them after use. Should you prefer retaining the 3D-printed or CNC-machined master model used in the production of the mold, please contact us personally so that we may talk.
