I. YH-791E characteristics and environmental protection advantages 1. Structure: linear SBS structure, styrene content 30%, prepared solvent glue, initial viscosity, tackability and softness and hardness balance.
2. Safety and environmental protection: It adopts an alkyl lithium catalytic system (no heavy metal residues), complies with RoHS, REACH and other environmental protection regulations, and is suitable for food contact grade and medical and health fields.
3. Solvent compatibility: It has excellent compatibility with environmentally friendly plasticizers (such as citrate, DINCH) and low-toxicity solvents (ethyl acetate, acetone), and can replace traditional benzene solvents.
II. Performance and application fields
1. Adhesive performance:
Strong initial adhesion: quickly wetting the substrate, suitable for high-speed coating processes (e.g. label tape production).
Adhesive stability: High cohesive strength, good creep resistance, suitable for long-term load scenarios (such as construction sealants).
2. Application scenarios:
Shoe industry: used for sole lamination, no solvent residual odor, high bonding strength.
Packaging and labeling: Prepare environmentally friendly pressure-sensitive adhesives for paper labels and film tapes.
Medical and hygienic: Biocompatibility tests can be used for medical tapes and dressing adhesives.
III. Potential for cost reduction and efficiency increase
1. Simplified formula: Due to its balanced performance, the amount of tackification resin or plasticizer can be reduced, reducing the cost of raw materials.
2. Compliance: Compared with PVC-based or benzene-based solvent adhesives, 791E is more in line with EU SVHC restrictions, helping export compliance.
3. Cost comparison: Compared with similar imported SBS (such as Keton D1101 and 1102), the price of domestic 791E is significantly lower and cost-effective.
4. Process optimization: fast dissolution speed, reduce energy consumption and man-hours (save 20%~30% dissolution time compared with some star SBS). Coating adaptability is wide (can be adapted to roller coating, spraying and other processes) to reduce the scrap rate.
