PAI (Polyamide-Imide)

PAI (Polyamide-Imide) PAI or polyamide-imide is one of the strongest polymers on the market today. It is also known for its resistance. Without additives, polyamide-imide has the ability to withstand extreme temperatures. This material remains unchanged even when exposed to a temperature of 270°C. Polyamide-imide or PAI is also very resistant...

PCTFE Properties

PCTFE Properties PCTFE, or polychlorotrifluoroethylene, is a thermoplastic that can be processed at temperature, resulting from the addition of a chlorine atom, which gives it its low melt index. This fluorinated plastic is moulded by hot injection and compression moulding or by extrusion and is characterised by its high tensile...

PCTFE vs PTFE

PCTFE vs PTFE

PCTFE vs PTFE PCTFE and PTFE are two fluoropolymers with similar chemical formulas. PCTFE is a derivative of PTFE composed of an additional chlorine atom. This atom is responsible for the low melt index of PCTFE. The coefficient of thermal expansion of PCTFE is also low compared to that of...
