Introduction
WM785D is produced by unique process in which carbon black is pre-dispersed, then compounded with the basic resin through plastication. It is widely used in modified compounding and injection applications. Suitable for PP and PE materials. It features low dosage, high blackness, good brightness, excellent heat resistance, outstanding dispersibility and tinting power, and minimal impact on the physical properties of the final product.
Technical Parameter
| Carbon Content | 17%±1.5 |
| Carrier | PE |
| MFI | 1-10(g/ 10min(230℃ 5 kg) |
| Moisture | ≤0.3% |
| Dispersion | Excellent (≤ Level 2.5) |
| Compliance | RoHS,REACH, FDA, TSCA |
| Application | Injection , Modified compounding |
| Dosage Advice | Injection: 0.8–2.0% Compounding : 1.0–4.0% |
| OEM | Accpeted |
Packing and Storage
25kg/bag, PE or Composite Paper bag
Stored under dry, enclosed and cool conditions, protected from UV rays and/or direct sunlight. After used, the opened packaging must be resealed properly to prevent the product from absorbing moisture, which could affect its performance.
Note
The technical results are typical values and are provided for customer reference only. They are not to be regarded as a guarantee of minimum or maximum quality specifications.
