1. General characteristics

P10 foam™ manufactured by DEDIENNE Multiplasturgy® is a rigid polyurethane foam with closed cells.


Main properties :

  • Very good mechanical rigidity
  • Transparency to hyperfrequency waves
  • Good performance at high temperature
  • Chemically stable

Applications :

  • P10 foam™ is generally used for the manufacture of radomes and antenna supports.
  • Due to its excellent thermal and mechanical properties, P10 foam™ can also be used for structural applications such as the core of complex and composite sandwiches.
  • For radio-electric applications, P10 foam™ can also be autoclave impregnated with a conductive charge to become MPU foam, see technical characteristics in our catalogue for hyperfrequency absorbers.
  • P10 foam is easily metallised and can therefore become a conductor on the surface. See the characteristics of our CEM metallisation.

2. Physical characteristics

2.1. Structure

P10 foam offers an alveolic structure made up of small cells. P10 foam can carry inclusions of a max diameter of 3mm, with a limit of 10 inclusions per dm3.

2.2 Apparent volumic mass

Grades available (nominal apparent volumic mass) :
48 kg/m3 , 128 kg/m3, 225 kg/m3, 380 kg/m3.
The tolerance on the apparent volumic mass is +/-15% for each grade.
N.B. Other grades can be manufactured on request.

2.3. Dimensions

Avajlable in all machined shapes and all dimensions in blocks of 600x600x200mm or 300x300x200mm

3. Mechanical characteristics

The constraints on bursting in ambient temperature compression must not be less than the following values :
Foam of a density of 48 kg/m3 : arc> 0.5 MPa
Grade 128 kg/m3 : arc> 1.3 MPa
Grade 225 kg/m3 : arc> 3.5 MPa
Grade 380 kg/m3 : arc> 15 MPa

4. Radio-electric characteristics at f =10 GHz

4.1 Measurement bank

The control of the tangent of dielectric constants and dielectric losses is realised by measuring in a resonating cavity at a frequency of 10 GHz, with the help of a vectorial network analyser.

4.2. Grade 48 kg/m3

Dielectric constante between 1.04 to 1.10
Loss tangent of < 6.20x10-4

4.3. Grade 128 kg/m3

Loss tangent of < 1.96x10-3

4.4. Grade 225 kg/m3

Dielectric constante between 1.25 to 1.36
Loss tangent of < 2.82x10-3

4.5. Grade 380 kg/m3

Dielectric constante between 1.40 to 1.73
Loss tangent of < 3.90x10-3

5. Traceability

5.1 Resin lots

The preparation of the resin is carried out in a reactor adapted to the size of blocks of foam to expand. Each lot of resin manufactured, carries an index in the form of a letter which is incremented for each new manufacture.

5.2 Foaming

Each foaming carries an incremental letter for each new foaming campaign, and also refers to the resin lot used :
Example : Resin lot D ; foaming D/A on 28/05 ; foaming D/B on 20/06, etc …

6. Certificate of conformity

Each delivery is accompanied by a certificate of conformity in line with reference NFL00-015 to the index in use.
