Polisilk it is a producer of PVDF multifilaments. They are suitable for any specific chemical and petrochemical application. Its high performances in the chemical and physic field make it necessary in certain applications. The main characteristics of SOLEF multifilament produced by Polisilk are:
* CHEMICAL RESISTANCE SOLEF PVDF has outstanding resistance to most mineral and organic acids, oxidising environments, aliphatic and aromatic hidrocarbons, alcohols and halogenated solvents. It is resistent to halogens, particularly to bromine and to weak bases. It is degraded by fuming sulphuric acid, some strongly basic amines, hot concentrated alkalis and alkaline metals. It swells in highly polar solvents such as acetone and ethyl acetate and is slightly soluble in aprotic solvents such as dimethylformamide and dimethylsulphoxide
* MECHANICAL PROPERTIES SOLEF PVDF has good mechanical properties in tension as well as in deflection, torsion, or compresion. The tensile stress al yield of 54 MPa observed with SOLEF 1010 is remarkably high by comparison with other polymers. SOLEF PVDF retains excellent mechanical properties between -40º and + 160ºC.
