About TSRC Corporation

TSRC Corporation was originally founded in 1973 as Taiwan Synthetic Rubber Corporation. Headquartered in Kaohsiung and Taipei, TSRC boldly expanded its footprint with operations and offices across China, Southeast Asia, the U.S., India, Vietnam, and Luxembourg, producing over 800,000 tons annually of synthetic rubber, including SBR, BR, NBR, TPE, and synthetic rubber compounds. Within the adhesives and sealants sector, TSRC’s specialty styrenic block copolymers (SBCs)—notably VECTOR SBS, VECTOR SIS, and Taipol/Vector SEBS—play a crucial role. These polymers are ideal for formulating hot-melt and pressure-sensitive adhesives, delivering fast drying, low shrinkage, strong tack/shear balance, low viscosity, and reduced emissions, key qualities that elevate tape, label, film, and sealing applications.

VECTOR® 4118ND

VECTOR® 4118ND by TSRC Corporation is a linear styrene-isoprene block copolymer developed for low-oil or oil-free hot-melt adhesive formulations in label applications. <br> <ul style="padding-left: 40px;"><li>It is designed for removable PSAs and food contact labels aligned with EU regulatory requirements.</li> <li> It supports efforts to reduce or eliminate MOSH while delivering outstanding processability. </li> <li>With high diblock (SI) content, very low styrene, and a narrow molecular weight distribution, it is exceptionally soft-comparable to pure polyisoprene-enabling effective label adhesion without milling. </li> <li>VECTOR® 4118ND offers low migration, enhanced die-cutting and stripping performance for high-speed label converting and reliable low-temperature adhesion, including on moist surfaces.</li></ul>

VECTOR® 4111A

VECTOR® 4111A by TSRC Corporation is linear, pure styrene-isoprene-styrene triblock copolymer. It is produced via proprietary sequential anionic polymerization technology and contains <1% diblock copolymer. It is not formulated with the antioxidant TNPP (tris(nonylphenyl) phosphite). It is low styrene, low modulus copolymer with outstanding thermal stability and melt processability. VECTOR® 4111A is the softest pure SIS triblock and is highly elastics and well-suited for use in elastomeric film compounds and in formulating adhesives.
