Keyflex® BT 2140D is a low-modulus, specialty thermoplastic copolyester elastomer (TPC) developed by LG Chem. It provides excellent mechanical strength, flexibility at low temperatures, and outstanding resistance to heat, chemicals, and weathering.
This grade is optimized for extrusion processing and is commonly used in films, sheets, hoses, and tubing, where durability, elasticity, and chemical resistance are critical.
Specific Gravity (ASTM D792): 1.14
Mold Shrinkage (ASTM D955): 1.1-1.5 %
Tensile Strength @ break (ASTM D638): 300 kg/cm²
Tensile Elongation @ break (ASTM D638): 700 %
Flexural Modulus (ASTM D790): 600 kg/cm²
Shore D Hardness (ASTM D2240): 39
MFR (ASTM D1238): 5 g/10min @ 230°C
