For the production of TPE profiles and seals, FinnProfiles has product lines that are suitable for a process known as co-extrusion. On these lines, we manufacture not only ordinary seals and profiles, but also profiles with two separate hardness. In contrast to the manufacturing of rubber and silicone profiles, TPE profiles are not vulcanised. In the manufacturing process of TPE profiles and seals, the process that forces the material through an extruder is followed by a cooling process during which the profile solidifies into the desired form. Every year, a total of approximately 250 tonnes of raw material are processed on FinnProfiles’ manufacturing lines.
TPE is plastic, with all the positive qualities of rubber. Seals made of thermoplastic elastomer have found widespread uses in industries, such as window and door manufacturing. This material is highly suitable for multi-component solutions which combine soft and hard materials in a single product.
The operating temperature range of TPE is wide, and it has excellent weather and chemical-resistant qualities. It can also be tinted in accordance with the RAL colour chart. However, TPE does not have as wide an operating temperature range as rubber or silicone.
The TPE quality that we use is SEBS, in other words, one of the styrene block copolymers.
