Dilavest™ P control point grades

Dilavest™ P grades offer a sharp expansion profile at a single, well-defined temperature with standard control points in the range 75°C to 120°C. Tailored products outside this range can be developed on request.

Dilavest™ L linear grades

The Dilavest™ L grades provide a linear expansion vs temperature response to give continuous control over a specified temperature range.

Dilavest™ C low temperature grades

Dilavest™ C control point grades are based on pure n-alkanes and are a suitable for control at specific temperatures in the lower temperature range from -18 to +40 oC.

wax in thermostats

Waxes are widely used in thermal actuation and thermostatic control devices, because it is possible to independently control
(i) the melting point and
(ii) degree of expansion in these materials.

our range of expansion waxes

Dilavest™ P control point grades are commonly used in the automobile sector for the adjustment of radiation cooling water, radiator fan and the oil system.
Dilavest™ grades are also used in the aerospace sector for control of lubricating oils and hydraulic fluids in the cooling systems.

A wide range of thermostat waxes with control points from 75°C to 130°C is available. Additional products outside this range can be developed and produced on request.

The Dilavest™ L linear grades are most commonly used in domestic applications for the regulation of radiator valves and control of heated water for domestic use, for example shower and mixer taps.

The standard grades are Dilavest L 0-30 for heating and Dilavest L 30-60 for hot water applications.

Customised linear grades can be developed to customers’ requirements.

Dilavest™ C grades are used in a number of sectors for control in the ambient temperature range for various control applications such as refrigerant systems, building ventilation and automotive air intake, for example carburetor or fuel injection systems.

Dilavest™ C grades are n-alkanes suitable for controls in a temperature range from -18 to +40oC.
