Keyflex® BT HB9242D is a low-modulus, alkali-resistant thermoplastic copolyester elastomer (TPC) developed by LG Chem. It provides excellent mechanical strength, outstanding flexibility at low temperatures, and exceptional resistance to heat, chemicals, and weathering.
This grade is optimized for extrusion blow molding and is widely used in automotive CVJ boots and bellows, where superior elasticity, toughness, and environmental durability are required.
Specific Gravity (ASTM D792): 1.14
Mold Shrinkage (ASTM D955): 1.5-1.9 %
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): 2.5 g/10min @ 230°C
