MR-H100 is a fully hydrogenated, water-white hydrocarbon tackifier with a nominal 100°C softening point and APHA color of 50 maximum. It is intended for hygiene and nonwoven adhesives, packaging hot melts, pressure-sensitive adhesives, assembly products, sealants, and color-sensitive compounds. Benchmark screening includes Escorez™ 5300, Eastotac™ H-100, and SUKOREZ® SU-100-class resins.
Typical values
The following are typical values informed by public hydrogenated-resin TDS data. They support initial selection only. Confirm the current Milorez TDS, agreed sales limits, and test conditions before commercial approval.
| Property | Typical value | Method / condition |
|---|---|---|
| Softening Point (R&B) | 100°C | ASTM E28 |
| Color (APHA / Hazen) | 30 typical; ≤50 maximum | 50% in toluene, ASTM D1209 |
| Acid Value | ≤0.1 mg KOH/g | ASTM D974 |
| Softening Point Variation | 95-105°C | Normal supply window |
| Melt Viscosity | 180-250 mPa·s | 180°C, ASTM D3236 |
| Wax Cloud Point | ≤85°C | EVA/resin/paraffin reference blend; confirm ratio |
| Appearance | Water-white transparent pellets | Visual |
Wax cloud point is not an intrinsic standalone resin constant. It must be reported with the reference EVA, wax, blend ratio, heating cycle, and observation method. Ask Milorez to align the method with your incumbent TDS before comparing values.
Formulation and application notes
MR-H100 can be evaluated with SIS, SEBS, selected SBS, EVA, APAO, metallocene polyolefins, polyisobutylene, butyl rubber, and compatible waxes and oils. Full hydrogenation is selected where initial color, color retention, and oxidative stability matter more than the broader polarity range of an aromatic resin.
For hygiene or nonwoven hot melts, test odor in the complete formulation, spray or slot-coat behavior, bond strength at low add-on, creep, and thermal aging. No raw-material data point by itself establishes suitability for skin-contact or regulated use.
For packaging and assembly adhesives, measure melt viscosity at production temperature, open time, set speed, fiber tear, heat resistance, and aging on the actual substrates. In PSA systems, compare loop tack, peel, shear, and failure mode. Full hydrogenation may improve color stability but does not guarantee compatibility with every polymer or plasticizer.
The published benchmark grades differ in softening point and viscosity test temperature. Normalize methods before drawing conclusions: 200 cP at 190°C is not directly comparable with 700 cP at 160°C.
Packaging, MOQ, and shipment
MR-H100 is supplied in 25 kg bags on pallets. Standard MOQ is 1 × 20’ FCL, approximately 18 metric tonnes. Milorez quotes FOB Xiamen or FOB Qingdao. A free 1-2 kg sample is available for laboratory qualification, with courier freight collected.
International grade comparison
MR-H100 occupies the broad water-white 100-105°C class associated with Escorez 5300, Eastotac H-100, and SUKOREZ SU-100, but it requires formulation validation; use the Escorez 5300, Eastotac H-100, and SUKOREZ comparison guides.

Frequently asked questions
Is MR-H100 fully hydrogenated?
Yes. MR-H100 is positioned as a fully hydrogenated, water-white hydrocarbon tackifier with APHA color controlled to 50 or below.
Which applications suit MR-H100?
Typical evaluation areas include hygiene and nonwoven adhesives, packaging hot melts, pressure-sensitive adhesives, assembly adhesives, sealants, and color-sensitive polymer modification.
Can MR-H100 directly replace Escorez 5300, Eastotac H-100, or Sukorez SU-100?
It can be screened in the same broad 100-105°C hydrogenated-resin class, but no universal drop-in claim is made. Polymer compatibility, viscosity, color stability, odor, and adhesive performance require validation.
Why does the wax cloud point include a blend condition?
Wax cloud point is formulation-dependent. A reported temperature is meaningful only with the EVA, resin, wax, ratio, and test procedure stated.
