Rheological modifier - Zhongli M7401

With the continuous maturity of optical fiber technology of communication cable, the research of optical fiber materials has gradually attracted people's attention. As an important part of optical fiber materials, ointment plays the role of sealing, moisture-proof, waterproof, buffering and protection in optical cable. The quality of the oil paste directly affects the transmission performance and use performance of the optical cable, and the M7401 produced by Zhejiang Zhongli is used in the optical cable optical fiber with very good weather resistance and heat resistance.

Rheological modifiers are products from petroleum refined materials, are used to improve the consistency or control viscosity and other rheological properties of additives, often referred to as "thickeners" exist in products, in our daily life for certain products to provide specific functions. It can not only be applied to communication optical fiber in our daily contact with the field of cosmetics also has a pivotal position, by adding thickener in cosmetics to change the appearance and stability of the product, want to adjust the rheological state of its products must choose the appropriate thickener to add to the product.

Zhejiang Zonli has a unique anionic polymerization technology. The M7401 product developed and produced by ZONli is a linear hydrogenated styrene-isoprene double block polymer, which is white powder in appearance and has the characteristics of good weather resistance, heat resistance, recycling and reprocessing, safety and environmental protection. Mainly used in optical fiber filling paste thickening, cosmetic thickening, can also be used as paint, lubricating oil, grease, adhesive, asphalt and other fields of rheological modifier.

The physical properties of the M7401 product are shown in the table

When two SEP polymers are mixed with the base oil, the styrene and rubber chains in the SEP polymers are connected to each other at the end and cannot form a cross molecular network, providing thixotrope properties (shear thinning) of the paste. The fiber optic fiber paste is kept viscous by the undisturbed entanglement of two SEP polymers. When subjected to external force, the linear polymers of two blocks either flow in orientation or form a granular lubricant, so that the gel becomes a sol state. Compared with inorganic gelling agents, polymer gelling agents have better miscibility with base oil, and their properties are more stable at higher miscibility temperatures.

The performance data of 10% concentration filling paste prepared with M7401 are shown in the table

Compared with other products, M7401 is innovative in the following aspects: Suitable polymer microstructure, SEP has oil solubility, the stability of the oil paste is very , the polymer obtained by advanced preparation technology has close to double block structure, al no triple block, the product in the formulation design and synthesis technology is at the advanced level of similar products in China.
