Special Features of OH Polymer LF-OHP


This product is synthesized from siloxane monomers and contains two hydroxyl groups at the ends of its molecular structure. In addition to sharing the typical properties of methyl silicone oil, it also exhibits the reactivity of hydroxyl groups. It can be utilized to create new materials or elastomers through cross-linking reactions.


Key advantages include:

Excellent electrical insulation and resistance to both high and low temperatures; High flash point and low freezing point; Superior water repellency and moisture resistance,Chemical and physical inertness; Low viscosity-temperature coefficient; High compressibility and low surface tension;

Applications of OH Polymer LF-OHP


At room temperature, it can react with crosslinking agents in the presence of catalysts, to form a reaction product, which has many excellent properties such as keeping good elasticity from -60℃-200℃excellent electrical property chemical stability and good resistance to water, odor, weather. Therefore, it can be widely used in many industries, such as electronics, semiconductors, autos, mechanicals, fabric, plastic, printing, construction, etc.


Package & Storage of OH Polymer LF-OHP


  • In 190kg/drum. 950kg/IBC or ISO TANK.  

  • Keep in cool, dry and ventilated place. Keep away from sunlight and fire sources. Keep in unopened containers, shelf life is 36 months from the date of production. It is shipped as non-hazardous substance.

  • Storage beyond the shelf life does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
