Tegris 6-ply sheet for rigid inserts

Milliken Tegris® is a grey thermoplastic composite sheet made from 100% polypropylene. Item 4000150274: 6 plies, 121 × 182 cm, 0.7 mm nominal thickness, ordered by the sheet. For rigid inserts, stiffeners and moulded components. The six-ply 0.7 mm execution suits projects with limited insert space. Finished-part stiffness depends on shape, size and attachment.

Polypropylene composite construction

Tegris uses polypropylene tape yarns with an ABA structure. During consolidation, the outer layers bond the fabric plies while the oriented core provides reinforcement. The manufacturer describes a combination of low density, stiffness and impact resistance, including at low temperatures. The woven surface appearance does not establish the presence of carbon fibre.

Thickness and properties of different material forms

Article 4000150274 specifies 6 plies and 0.7 mm nominal thickness. The general datasheet’s 0.125 mm per ply is a typical consolidation result; multiplying it does not replace the item specification. Unconsolidated fabric has separate 0.40 mm and 98 g/m² values, and the 14 GPa modulus applies to tape yarn rather than the finished sheet.

Processing and combination with other materials

The sheet can be cut and formed to the required geometry. Milliken describes heat-and-pressure consolidation, bonding to other materials using a dedicated bond layer, and painting after suitable priming. Select processing conditions, adhesive and coating for the design and validate a sample; the tape yarn’s 120 °C sealing value is not a universal sheet-pressing instruction.

Colours and illustration

This item is grey. The supplied sheet lists silver, white and black/graphite family colours; the currently published Milliken document lists Coyote and Grey/Silver. This does not establish availability of every colour for this article. The prepared illustration uses a manufacturer reference to show the family appearance; assess the exact shade, weave and thickness using a sample.

Reading the impact test data

Both PDFs contain inconsistent J/ft-lb pairs for Gardner Dart Impact. The table retains them with a note, without guessing which number is correct. Obtain Milliken clarification before using them in engineering calculations. Thermal expansion is shown with the negative 10⁻⁶ exponent from the current PDF. A general material datasheet is not a ballistic certification of a finished assembly.

Ordering and sheet selection

Specify article 4000150274, 6 plies, 121 × 182 cm format, grey colour and sheet quantity. Include requirements for the finished part, cutting or samples. A DELIM manager will confirm availability, price, minimum quantity and lead time.

Verified specifications

Material construction: Fabric woven from ABA tape yarns; the outer A layers melt below the B core. Heat and pressure consolidate the sheet.
Scope of the following values: Typical Tegris family properties, not test results for this thickness or batch. Sheet properties depend on pressing conditions.
Sheet: bulk density: 0.78 g/cm³ — ASTM D792
Sheet: typical consolidated thickness per ply: 0.125 mm/ply (0.005 in/layer). Do not substitute this typical value for the item’s specified nominal thickness.
Sheet: tensile strength: 200 MPa (30 kpsi) — ASTM D638
Sheet: tensile modulus: 5–6 GPa (720–870 kpsi) — ASTM D638
Sheet: elongation at break: 6% — ASTM D638
Sheet: flexural modulus: 5–6 GPa (720–870 kpsi) — ASTM D790
Sheet: heat deflection at 1820 kPa: 95 °C — ASTM D648
Sheet: heat deflection at 455 kPa: 130 °C — ASTM D648
Sheet: thermal expansion, −60 to +40 °C: 6 × 10⁻⁶ /°C; 3 × 10⁻⁶ /°F — ASTM D696, from the current Milliken PDF.
Sheet: Gardner Dart Impact at −40 °C: Source values: 24.7 J and 33.6 ft-lb, ASTM D5420. The unit pair is inconsistent; the numerical result requires manufacturer clarification.
Sheet: Gardner Dart Impact at +20 °C: Source values: 24.5 J and 33.3 ft-lb, ASTM D5420. The unit pair is inconsistent; do not treat it as a verified conversion.
Sheet: notched Izod impact: 4.8 kJ/m; the second PDF notation is 90 ft-lbf/i (as printed); the table does not identify a test method.
Unconsolidated fabric: thickness: 0.40 mm — ASTM D1777
Unconsolidated fabric: areal density: 98 g/m² (3.0 osy) — ASTM D3776
Fabric: standard roll width: 127 cm (50 in)
Fabric: peak load, warp / fill: 720 / 660 N (160 / 150 lbf) — ASTM D5035, 1-inch strip
Fabric: elongation, warp / fill: 7.8 / 7.1% — ASTM D5035, 1-inch strip
Fabric: tape count, warp / fill: 11 / 11 tapes per inch — ASTM D3775
Tape yarn: tensile modulus: 14.0 GPa — ISO 527
Tape yarn: shrinkage at 130 °C: Less than 5.5% — ASTM D4974
Tape yarn: sealing temperature: 120 °C — Milliken method; not a complete forming cycle for a multilayer sheet.
Tape yarn: linear density: 1020 denier — ASTM D1577
Family weave options: Plain, twill and herringbone, with custom options. Confirm the weave of the specific article against a sample.
Family colours in the supplied PDF: Silver, white and black/graphite; a general source palette, not variants of this grey item.
Family colours in the current Milliken PDF: Coyote and Grey/Silver. Confirm other colours and articles separately.
Standard family sheet formats: 48-inch width (approximately 122 cm), lengths up to 120 inches (approximately 305 cm). This item has its own 121 × 182 cm format.

Applications and compatibility

Rigid inserts and stiffeners for equipment, luggage, cases and moulded components, subject to design and sample validation.
Check sheet fit, bend radii, holes, fasteners and adhesive compatibility with PP. Assess the finished assembly separately from typical raw-material properties.
