Keyflex® BT 1028D is a general-purpose, low-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 typically used in applications where soft touch, durability, and environmental resistance are important.
Specific Gravity (ASTM D792): 1.05
Mold Shrinkage (ASTM D955): 0.4-0.8 %
Tensile Strength @ break (ASTM D638): 200 kg/cm²
Tensile Elongation @ break (ASTM D638): 900 %
Flexural Modulus (ASTM D790): - kg/cm²
Shore D Hardness (ASTM D2240): 25
MFR (ASTM D1238): 25 g/10min @ 230°C
