SUNION Class S-1552 is a linear tri-block and pure SI di-block hybrid product, using styrene and isoprene as monomers, and a thermoplastic elastomer synthesized by anion. The product is compact particle, and it has transparent or translucent particle appearance, which is similar to most of the hard plastic, with 16% styrene content and 52% the di-block content. The advantages of S-1552 are material pipeline, high efficiency and low labor costs by twin screw extrusion modification or direct injection produce process.

1. Label glue application
S-1552 contains 52% of SI di-block, and the product has high initial adhesion and good die-cutting effect, so it can be used for production of label glue.
2. Masking tape application
S-1552 has high SI di-block, and it is good at resisting low temperature. It is often used to adjust the glue weather ability, preventing masking tape from the glue to harden, drier during winter.
Packing
Our product is securely packed in durable 25kg woven bags to ensure its integrity during transportation.
Attentions
S-1552 belongs to combustible, and that should be away from fire and heat source and corresponding high oxidizing material. It also has double bonds in the internal structure which may be cross linked and cracked by the sunlight or ultraviolet radiation. Therefore, it should be avoided sunlight or strong light irradiation, and be stored in a cool, dry and ventilated warehouse.
