Keyflex® BT 1063D is a general-purpose, high-modulus thermoplastic copolyester elastomer (TPC) developed by LG Chem. It offers excellent mechanical strength, flexibility at low temperatures, and outstanding resistance to heat, chemicals, and weathering.
This grade is suitable for both extrusion and injection molding and is commonly used in injection-molded components for automotive, leisure, and sports applications, where durability, toughness, and environmental resistance are important.
Specific Gravity (ASTM D792): 1.23
Mold Shrinkage (ASTM D955): 1.3-1.7 %
Tensile Strength @ break (ASTM D638): 420 kg/cm²
Tensile Elongation @ break (ASTM D638): 450 %
Flexural Modulus (ASTM D790): 3,100 kg/cm²
Shore D Hardness (ASTM D2240): 60
MFR (ASTM D1238): 24 g/10min @ 230°C
