Fabrications
Saw Cutting| Description | Correx® is an extruded board made from polypropylene co-polymer granules along with additional components to confer specific characteristics to the product. |
|---|---|
| Nominal Weight | Board weight and thickness can be engineered to cater for specific requirements such as enhanced compression characteristics. |
| Thickness | Correx® board is available in 2mm, 3mm, 4mm, 6mm and 10mm thickness. |
| Dimensions | Correx® utilises standard board conventions when specifying length and width, i.e. the first dimension (f) is the flute length and the second dimension is the width across the flutes. |
| Mullen Bursting Strength | Correx® does not burst in the Mullen Tester. |
| Combustibility | Polypropylene is a combustible thermoplastic material. The products of combustion are carbon dioxide, carbon monoxide, smoke and low concentrations of breakdown and oxidation products such as formaldehyde. Fire precautions consistent with regulatory codes and standards for comparable materials should be observed. |
| Toxicity | Correx® is chemically unreactive and is generally regarded as being biologically inert. However, coloured grades docontain additives that could be harmful, and ingestion is not recommended. Direct skin contact with Correx® does not normally lead to skin irritation. |
| Inflammability | (Data on resin used in extruding Correx®) Minimum self-ignition temperature ca 375 deg C (ASTM D 1929) Minimum flash-ignition temperature ca 310 deg C (ASTM D 1929) UL flame class 94HB. Oxygen index 17.4% – 18% (ASTM D 635) Softening temperature ca 144 deg C. Crystalline melting point ca 160 deg C. Flame retardant grade to BS 2782 Method 508A (1970 Rate of burning) and LPS1207 : Issue 1 : 1994 |
| Resistance | Correx® is inert to most mineral and organic acids, oils, greases and alcohols. It causes very little abrasion and is resilient and shatter proof. It is totally impervious to water. |
| Flexing | A property of Correx® is its outstanding resistance to flex fatigue. |
| Durability | Correx® does not rip or tear and is virtually indestructible. It is photodegradable. |
| Light Transmission | Translucent grade 75%. |
| Cutting | Correx® can be cut with a Stanley Knife, electric saw, guillotine or platen. |
| Joining | Stapling, ultra-sonic welding and silicone glues. |
| Colours | Correx® is available in primary colours from stock or special colours to order including colour matching systems. Colours are not designed for outdoors light fastness. |
| Insulation | Correx® is a good acoustic and thermal insulator. Typical U-value 3.8 w/m2 deg C. Correx® is a CFC free product. |
| Quality Assurance | We work to a quality management system commensurate to BS 5750 Part 2 (ISO9002). |
| Four Colour | Use ink manufacturers recommended inks. To minimise expansion it is advisable to run Correx® through the drier prior to printing the first colour to warm the board to its printing temperature. Run the drier at a low temperature and put all colours down in quick succession to ensure the board temperature stays as constant as possible. These precautions are necessary if register is to be maintained. Correx® will expand by 1mm per 1000mm length of board through 10 deg C rise in temperature. |
