【Production Introduction of Hydroxypropyl methyl cellulose】
Hydroxypropyl methyl cellulose (HPMC) is a natural polymer materials as raw materials,through a series of chemical processing and prepared non-ionic cellulose.
【 Advantages of adding HPMC to colored pencils】
Hydroxypropyl Methylcellulose (HPMC) can be used as the binder and plasticiser for the shaping of colored pencils and crayons.
1. After HPMC is added, the lead of the pencil achieves a higher flexibility and a higher braking
strength, it is not easy to break.
2. HPMC is used as a fixing agent to get smooth texture and vibrant colors.
3. As a molding adhesive for color pencil, it does not agglomerate.
4. High compatibility in combination with all other raw materials used.
【Technical requirements】
1. Appearance: white to yellowish powder or grains.
