Keywords: SBS; Yuehua; 791E; I. Properties and Environmental Advantages of YH 791E Structure: Linear SBS structure with 30% styrene content. The solvent-based adhesive prepared exhibits a balanced balance of initial tack, holding power, and hardness. Safety & Environmental Protection: Produced with an alkyl lithium catalyst system (no heavy metal residues), compliant with environmental regulations such as RoHS and REACH. Suitable for food contact and medical & healthcare applications. Solvent Compatibility: Excellent compatibility with eco-friendly plasticizers (e.g., citrate esters, DINCH) and low-toxicity solvents (ethyl acetate, acetone). Can replace traditional benzene solvents. The resulting solvent adhesive contains no benzene volatile substances, avoiding environmental pollution and respiratory irritation. II. Performance and Application Fields 1.Adhesion Performance: Strong Initial Tack: Rapid wetting of substrates, suitable for high-speed coating processes (e.g., label and tape production). Stable Holding Power: High cohesive strength and excellent creep resistance, ideal for long-term load-bearing applications (e.g., construction sealing tapes). 2.Application Scenarios Footwear Industry: Used as sole bonding adhesive with no residual solvent odor and high bonding strength. Packaging & Labels: Used to produce eco-friendly pressure-sensitive adhesives for paper labels and film tapes. Medical & Healthcare: Products that pass biocompatibility tests can be used in medical tapes and dressing base adhesives. III. Cost Reduction & Efficiency Improvement Potential Formula Simplification With balanced inherent properties, it can reduce the dosage of tackifying resins and plasticizers, lowering raw material costs. Compliance Compared with PVC-based or benzene-containing solvent adhesives, 791E better meets EU SVHC restriction requirements, supporting export compliance. Cost Comparison Compared with similar imported SBS (e.g., Kraton D1101, D1102), domestic 791E has a much lower price and significantly higher cost-performance ratio. Process Optimization 1.Fast dissolution rate, reducing energy consumption and working hours (saves 20%–30% dissolution time vs. some star shaped SBS). 2.Wide coating adaptability (compatible with roll coating, spray coating, etc.), reducing reject rate.
