Jusage™ SIS Series
1120
A linear SIS grade for label, tape, and selected pressure-sensitive adhesive formulation discussion.
Review typical reference data, application directions, and the technical data sheet for SIS 1120. Final material selection should be confirmed through formulation, process, and trial evaluation.
Application And Trial Discussion
Direct answer:SIS 1120 is a linear SIS grade often discussed for hot-melt pressure-sensitive adhesive work where labels, tapes, sealants, and selected polymer modification systems need a balance of formulation flexibility, processing behavior, and trial-stage tack/cohesion adjustment.
Labels and tapes
Sealants
Selected polymer modification systems
General hot-melt PSA development
Recommended when customers need a broader-use SIS grade with good processing behavior and formulation flexibility.

Selection Factors To Confirm
| Buyer Question | What To Review Before Selecting SIS 1120 |
|---|---|
| Application fit | Confirm whether the project is closer to labels, tapes, sealants, or a broader hot-melt PSA development route. |
| Formulation balance | Review tackifier, oil, antioxidant, and additive compatibility instead of choosing by SIS grade name alone. |
| Processing route | Compare melt temperature, coating method, viscosity window, and line-speed expectations during trial planning. |
| End-use environment | Check substrate, service temperature, aging exposure, peel target, holding power, and residue requirements. |
Buyer Checklist
Share the target application, substrate, coating process, and expected trial scale.
Prepare the current or target formulation direction, including tackifier and oil system if available.
Confirm whether a technical data sheet, sample discussion, or grade comparison is needed first.
Record the test method used for peel, tack, holding power, heat resistance, or aging so trial feedback is comparable.
SIS 1120 FAQ
Is SIS 1120 only for labels and tapes?
No. Labels and tapes are common discussion areas, but SIS 1120 can also be reviewed for sealants and selected polymer modification systems when the formulation and trial goals match.
Can SIS 1120 be selected from typical data alone?
No. Typical reference data helps screening, but final selection should be confirmed through formulation trials, substrate testing, process review, and end-use validation.
When should buyers compare alternative SIS grades?
Compare alternatives when the project requires a different styrene level, diblock direction, viscosity window, heat resistance balance, or adhesive performance profile.
