Glysofor ELP

Description

Glysofor ELP is a high-purity grade propylene glycol, which is available in any concentration.

The product is used for applications which require extremely low electrical conductivity.

Glysofor ELP can be delivered as a concentrated high-purity product or as an aqueous solution. The solutions are manufactured using high-purity water with an electrical conductivity < 0.1μs/cm.

Specific electrical resistance at 20 °C (M ohm cm)	min. 10
Specific electrical conductivity at 20 °C (μs/cm)	max. 0,1
Dielectric constant	approx. 28

Further information

Glysofor ELP optimally prevents frost damage, deposits, sludge accumulation, and biofilms in water circuits. Due to its safety, Glysofor ELP can be used in environmentally sensitive applications. It is biodegradable and environmentally friendly. Both as a concentrate and diluted with water, the product is classed in the lowest water pollution class WGK 1. It exhibits longterm resistance to the formation of biofilms, rot, and microbiological decomposition. Glysofor ELP can be mixed in any ratio with water, ethanol, butanol, butyl acetate, and acetone. We supply high-purity water with an electrical conductivity < 0.1μs/cm for you to make subsequent adjustments. Homogeneous Glysofor ELP/water mixtures do not separate, which ensures that the characteristics of the product remain consistent. This guarantees longterm low-maintenance operation of the system.

Antifreeze

Glysofor ELP significantly reduces the freezing point of water, thereby preventing freezing in water circuits and cooling systems.

With Glysofor ELP, water circuits can be temporarily switched off, even during frost conditions, while however remaining ready for operation at any time. Homogeneous mixed aqueous solutions do not separate when the system is shut down.
