Keyflex® BT 1155D is a general-purpose, medium-modulus 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 suitable for both extrusion and injection molding and is commonly used in cable and wire jackets, hoses, tubing, and sheets, where durability, toughness, and environmental resistance are essential.
Keyflex® BT 1155D is compliant with GM QK 006715 specifications.
Specific Gravity (ASTM D792): 1.18
Mold Shrinkage (ASTM D955): 1.0-1.4 %
Tensile Strength @ break (ASTM D638): 350 kg/cm²
Tensile Elongation @ break (ASTM D638): 550 %
Flexural Modulus (ASTM D790): 1,700 kg/cm²
Shore D Hardness (ASTM D2240): 52
MFR (ASTM D1238): 14 g/10min @ 230°C
