Anti-ozone wax CR211/CR217/CR287/CR220
DETAILED DESCRIPTION
| Types | Appearance | Congealing Point ℃ (ASTM D938) | Viscosity@100℃ cst (ASTM D445) | Refractive index@100 ℃ (ASTM D1747) | Dosage | Recommended temperature ℃ | Applications |
|---|---|---|---|---|---|---|---|
| RW211 | White or light yellow granules | 63 - 69 | 6.0 - 8.0 | 1.428 - 1.440 | 1 - 5 phr | 5 - 45 | Mixture of paraffin wax and microcrystalline wax Medium and high temperature protection After vulcanization, it will form a wax film which protects from atmospheric ozone attacks. It has a medium rate of migration which ensures a long time protection. Better performance with antioxidant. |
| RW217 | White or light yellow granules | 70- 75 | 6.0 - 9.5 | 1.435 - 1.445 | 1 - 5 phr | 20 - 50 | |
| RW287 | White or yellow granules Penetration at 25℃ (ASTM D 1321):10 - 25 dmm | 63 - 69 | 6.3 - 8.2 | 1.426 - 1.435 | 1 - 5 phr | 5 - 45 | |
| RW220 | Yellow, brown granules | 61 - 67 | 6.3 - 7.5 | 1.423 - 1.433 | 1 - 5 phr | 5 - 45 | Bimodal protection: It has a wide molecular weight distribution and shows as a typical bimodal curve. After vulcanization, it will form a wax film which protects from atmospheric ozone attacks. It has a medium rate of migration which ensures a long time protection. Better performance with antioxidant. |
