Polyamide 6.3T (PA 6/3/T)
Description (definition)
Polyamide 6.3T (PA 6/3/T) is a special copolyamide formed by the polymerization of hexamethylenediamine (C6), trimethylene terephthalic acid (T) and another monomer (C3). This material combines high thermal stability with excellent chemical resistance and mechanical properties. Due to these properties, PA 6/3/T is often used in the automotive, electrical and household appliance industries for components that have to work under high loads and temperatures.
An example
One example of the use of PA 6/3/T is in coolant tanks in vehicles. Its oil and temperature resistance enables a long service life and reliable function in engine environments.
How is polyamide 6 produced?
Polyamide 6 is produced by the ring-opening polymerization of caprolactam. This process produces long polymer chains that make the material flexible and resistant. Due to its properties, PA6 is used in many technical applications such as gears, housings and textiles.
Is PA6 oil-resistant?
Yes, polyamide 6 is oil resistant, but the resistance depends on the specific formulation and operating conditions. For applications in the automotive industry, PA6 is often used with additives or in copolymer forms such as PA 6/3/T to ensure even better resistance to oils and lubricants.
What advantages does PA 6/3/T offer over other polyamides?
PA 6/3/T offers greater thermal stability and chemical resistance than conventional PA6. It is less susceptible to moisture absorption and remains dimensionally stable even under extreme conditions. These properties make it ideal for applications that require high resilience and resistance.
