StruCell® P300 Structural PVC Foam Core

StruCell® P300 Structural PVC Foam Core Description

StruCell® P300 is the highest-density grade of the StruCell® structural PVC foam core series, with a density range of 290-330 kg/m³ (Technical Data Sheet: Density 290-330, Max.). It is a closed-cell, cross-linked PVC foam developed for sandwich structures that must carry concentrated loads, high bearing stress and demanding fastener pull-out requirements, where lower-density cores would require thicker sections or additional local reinforcement.

Key Features & Benefits

• High bearing capacity: TDS average values of 7.6 MPa compressive strength and 5.9 MPa shear strength - the highest values in the StruCell® range.

• Stiff sandwich design: 450 MPa compressive modulus and 450 MPa tensile modulus help limit deflection in highly loaded panels.

• High strength-to-weight ratio: approximately 300 kg/m³ density with tensile strength of 11 MPa (TDS average).

• Closed-cell structure: low resin absorption and low water absorption for marine and outdoor service.

• Process compatibility: hand lay-up, spray-up, vacuum infusion, resin transfer moulding and press bonding.

• Machinable: kitting, grooving, perforating and CNC-machined parts available - see CNC custom PVC foam parts.

Grade Comparison: P200, P250 and P300

P200 and P250 values are the published StruCell® series values; P300 values are Technical Data Sheet values. For a full density-to-property overview, see the PVC foam core density chart. If a lower density already satisfies the design load, compare StruCell® P250 and StruCell® P200.

Why Choose StruCell® P300 PVC Foam Core?

• Highest load capability in the series: 7.6 MPa compressive and 5.9 MPa shear strength (TDS average) allow thinner cores, fewer inserts and simpler local reinforcement.

• Built for stiffness-critical parts: 450 MPa compressive and tensile modulus support highly loaded panels and tooling.

• Consistent closed-cell core: uniform cell structure for repeatable resin uptake and bonding in infusion and RTM processes.

• One supplier, full range: from StruCell® P130 up to P300, so you can tune core density across a single structure.

Surface Technology

StruCell® P300 is supplied with the surface formats used across the StruCell® range, selected to match your resin system and process:

• Plain board - for hand lay-up and flat press bonding.

• Grooved board (single or double sided) - for faster resin flow in infusion; see grooved PVC foam core for faster infusion.

• Punched / perforated board - for through-thickness resin flow.

• Scrim board - with a fibre mesh backing to hold core alignment on curved moulds.

• Hyperbolic (double-curved) board and custom surface treatments for complex geometry.

FAQs

What is the density of StruCell® P300 PVC foam core?

The Technical Data Sheet states a density range of 290-330 kg/m³ (maximum value). This makes P300 the highest-density grade in the StruCell® structural PVC foam core series.

What is the compressive strength of PVC foam core P300?

7.6 MPa average value and 7 MPa minimum value, with a compressive modulus of 450 MPa average (400 MPa minimum).

How does StruCell® P300 perform in shear?

Shear strength is 5.9 MPa average (4.9 MPa minimum) and shear modulus is 120 MPa average (100 MPa minimum).

What thicknesses and board sizes are available for P300?

StruCell® P300 is supplied in 15/16 mm, 22 mm, 30 mm, 33 mm and 40 mm thickness, with plain boards at 1300 × 610 mm / 1300 × 620 mm and grooved, perforated or contour boards at 650 × 620 mm. Other sizes and thicknesses are produced to order - send your drawing for confirmation.

Which processing methods are compatible with P300?

Hand lay-up, spray-up, vacuum infusion, resin transfer moulding and press bonding. Grooved and perforated formats are available for faster resin movement in infusion.

Can PVC foam core P300 be machined or supplied as kits?

Yes. It machines cleanly and can be supplied as cut-to-size panels, grooved or perforated sheets and CNC-machined parts. See CNC custom PVC foam parts for detail.

What is the minimum order quantity and delivery time?

There is no MOQ - free A4 samples are available. Small batches ship in 5-7 days and full container quantities in 15-20 days.

Which grades should I compare with P300?

If a lower load capability is acceptable, StruCell® P250 and StruCell® P200 offer progressively lower density and weight. The StruCell® structural foam core range covers seven densities from 48 to 300 kg/m³.
