PEO-8Z is a non-ionic water-soluble resin, a high molecular weight white powder.
The molecular weight of PEO-8Z is between 170 and 2.2 million. At 25 ° C, the viscosity of 5% PEO-8Z aqueous solution is between 20 and 70 mpa.s
Characteristics of PEO-8Z:
· Completely water soluble
· Soluble in many solvents
· PEO is a non-ionic polymer
· Efficient thickening (even with very high viscosity at very low concentrations)
· Because it is a thermoplastic resin, it has good ductility, plasticity and bending properties
· Prevent the invasion of creatures
· Reduce the friction of liquid
· Can be combined with a variety of polar resins (such as urea-based resin, acrylic, furan resin, etc.)
· Low toxicity
使用指南：
尽管PEO树脂是完全水溶性的，但如何把PEO粉末完全分散在水中是制取水溶液的关键。一种简单的方法是在适当的搅拌速度下（1- 1.5m/s），把PEO逐步加入水中。配置好的黏结剂胶液呈透明澄清状，放置后无杂质沉淀。
需要注意的是：
·PEO是高分子量树脂，高速搅拌会将其分子链打断，降低胶液黏度，因此应控制搅拌速度。
·PEO水溶液见光（尤其是紫外光）易分解，因此配好的粉浆要遮盖并储存在阴凉地方。
·PEO水溶液黏度受温度影响较大，温度升高黏度下降，配置时应尽量保持环境温度的稳定。
