Thermoplastic seals (TPE, TPV)
Description and use – they represent a special type of gaskets, included in this group, such as gaskets for plastic and wooden windows of various manufacturers (EURO, etc.), which sufficiently replace silicone gaskets.
Plastic compounds are modified by rubber additives, which allow these gaskets a wide range of applications – across all sectors of economic activity.
Properties – very good properties of permanent deformation and resistance to weather conditions in the temperature range of -40 °C to + 70 °C. They are also characterized by good physical and mechanical values.
Design – they are produced in several basic shapes, such as square, rectangle, circular gasket, intermediate ring, or specific shapes.
Material basis – they are currently made of a TPE-based material with a specific weight of about 1.2 g / cm 3 and a hardness of 30 – 60 °ShA.
