SOLBIN CH – Shin-Etsu MicroSi

Solbin® CH


Datasheet: Solbin CH TDS_3.2014RS


Solbin CH is a thermoplastic resin consisting of polyvinyl chloride (VC) and polyvinyl acetate (VAc). It has a higher
molecular weight and produces a solution with a higher viscosity than Solbin C.

Product Description

  • Soluble in ketones, esters and chlorinated hydrocarbons. Use aromatic hydrocarbons as diluent solvents. Insoluble in alcohol, oil and aliphatic hydrocarbons.
  • Chemically stable and is unaffected by acids and alkalis at normal temperature.
  • It combines high water resistance with low moisture permeability and low water absorption.
  • Tough, resilient and non-flammable.
  • Solbin CH is colorless and transparent with a high refraction index, it can be changed into any bright color and produces a highly glossy film.
  • It possesses an excellent ability to resist the effects of weather and aging.
  • As a thermoplastic, films made with Solbin C can be easily heat sealed.
