一、Product presentation
The FST-K series is a light yellow granular thermoplastic solid resin, which is mainly composed of carbon five-fractions and carbon nine-fractions produced by ethylene devices, and is a low molecular weight polymer generated by polymerization reaction under certain temperature and pressure conditions under special production processes.It has good compatibility with natural rubber (NR), synthetic rubber, styrene polymers (e. g., SIS, SBS, SEBS, EVA), and is well compatible with natural adhesive resin (e. g., terpenes, rosin and its derivatives).It has the advantages of C5 resin and C9 petroleum resin.It has the characteristics of low acid value, good miscibility, water resistance, ethanol resistance and chemical resistance, has chemical stability to acid and base, and has good regulation of viscosity and thermal stability.Because the structure does not contain polar groups in the structure, it has good water resistance, acid-and alkali resistance, weather resistance and light-aging resistance. In organic solvents, especially in petroleum solvents, it has good solubility, good solubility with other resins, but also has certain fragility, viscosity, adhesion and plasticity.It is generally not used alone, but is used together as promoters, regulators, modifiers, and other resins.
二、Product application field
This product is used for hot melt glue, pressure-sensitive glue and sealant, Binders such as civil adhesives and adhesive resin in the field of rubber and tires; In the field of hot melt glue, adhesives and adhesives, This product can not only provide a better initial viscosity, And can be like the rosin resin, It can be used to adjust the viscosity and adhesive strength of the adhesive and resin mixture; Suitable for the rubber, Tire industry; Suitable for road hot melt road paint, Good characteristics of weather resistance and flow parallelism, And the highway hot melt road standard paint base oil; Especially compared with the product for hot melt road standard paint base oil and C5 petroleum resin for hot melt road standard paint base oil, Make the paint surface and the pavement have a stronger combination force and impact resistance, more solid, More effective to prevent the loss of the paint surface problem.In addition, this product can also be used in paint, ink, such as printing ink, gravure printing ink, copper plate printing ink of high-grade printing ink and other industries.
