FAQs

What are the advantages of Tepex® thermoplastic composites vs. thermoset composites?
Thermoplastic composites withstand high loads but at the same time are light. They are in addition cleaner, stronger and in general more cost-effective than composites involving thermoset plastics. The mechanical properties are comparable with those of thermoset composites, however Tepex® is much tougher, especially at low temperatures.


How is Tepex® made?
Bond-Laminates is the first company to use a double-belt press for the continuous production of Tepex®. The double-belt press permits laminating on a volume production basis, with consistently high product quality coupled with low production costs.

In what sizes and thicknesses is Tepex® available?
Tepex® is available in thicknesses ranging from less than 0.1 mm to more than 6.0 mm. The length is fundamentally unlimited, the only restricting factor being ease of transportation.

What Tepex® types are there?
Tepex® is manufactured with glass, carbon and/or aramid fibers. Virtually any thermoplastic, for example PP, PA, TPU, PPS etc., can be used as the matrix material. Almost all materials can be optimised to incorporate specific requirements, depending on application. The customer always obtains what is the best and most economical solution for their specific application.

Which 
Tepex® material is the best for my purposes?
That depends on a variety of factors: the mechanical loads encountered, the thermal and chemical operating conditions, the desired weight, the quality of finish required, etc. We will gladly advise you on choosing the optimum material for your purposes.

What mechanical properties does 
Tepex® possess?
The mechanical properties depend on which fiber and matrix material are used, as well as on the weave structure of the fibers. All Tepex® types are very strong, rigid and impact-resistant, though the carbon and aramid-based material types are even stronger and more rigid than the glass-based materials.

What thermal properties does Tepex® possess?
The thermal properties depend on the type of thermoplastic used. Melting temperatures range from 165 °C to 300 °C, and maximum operating temperatures between 60 °C and 200 °C.

What chemical properties does Tepex® possess?
The chemical properties are likewise determined mainly by the matrix material. Most Tepex® types exhibit high chemical resistance, and the PPS line in particular is notable for its excellent resistance to a wide range of chemicals.

How is Tepex® shaped to form products?
There are a number of forming techniques for Tepex®; which one is used depends on the geometry of the product and the quantity to be produced. For a detailed explanation, see our website, under the menu item Processing technologies.

What processing times are achieved for forming Tepex®?
Most products can be formed in 20 – 60 seconds.

What does Tepex® cost compared to other materials?
The prices for Tepex® depend on the material type, structure and quantity. Prices per kilogram are generally higher than for steel or aluminium. Thanks to the much lower material density and the cost-effective production technology, the prices of the finished products are comparable to or actually lower than those for metal and thermoset parts. The material price has to be evaluated taking the complete value chain into account. There is always a good Tepex® material for your budget!
