KTR
| 1.PRODUCT INTRODUCTION
KOSYN KTR is a family of styrenic thermoplastic elastomers manufactured by the Korea Kumho Petrochemical Co., Ltd. KOSYN KTR grades are linear or radial block copolymers synthesized with butadiene and styrene monomer in organic solvent. They have good tensile strength, elasticity and processability without chemical cross-linking such as vulcanization.
