Keyflex® BT 1245D is a medium-modulus, specialty thermoplastic copolyester elastomer (TPC) developed by LG Chem. It offers excellent mechanical strength, superior low-temperature flexibility, and outstanding resistance to heat, chemicals, and weathering.
This grade is designed for injection molding and is commonly used in automotive body plugs and fasteners, where durability, dimensional stability, and environmental resistance are essential.
Specific Gravity (ASTM D792): 1.13
Mold Shrinkage (ASTM D955): 1.4-1.8 %
Tensile Strength @ break (ASTM D638): 300 kg/cm²
Tensile Elongation @ break (ASTM D638): 600 %
Flexural Modulus (ASTM D790): 1000 kg/cm²
Shore D Hardness (ASTM D2240): 44
MFR (ASTM D1238): 25 g/10min @ 220°C
