Supplying Composite Materials

The Composites division of DIATEX offers consumables and equipment for the following 4 processing systems: Vacuum Moulding of Composites, Vacuum Infusion of Composites, RTM Injection (resin transfer molding) and Light RTM Injection.


Multilayer Systems for Vacuum Infusion


Diatex offers two ranges of multilayer systems for vacuum infusion : INFUPLEX (2 layers) and INFUPEEL (3 layers).

INFUPLEX and INFUPEEL are multilayer systems used in manufacturing processes for vacuum infusion of composite materials. Products include:





Vacuum infusion multilayer systems

INFUPLEX® are multilayer systems found in manufacturing processes for vacuum infusion of composite materials. The systems combine two vacuum consumables into a two-layer unit (a performed film and a net bleeder on top). There are 7 INFUPLEX® versions with 7 different infusion medias.

INFUPLEX® is also a very simple solution to lay up the bagging materials.


Infusion Medias


In order to meet an increasing demand for high temperature vacuum infusion solutions, Diatex has developed a specific range of infusion medias withstanding temperature up to 200°C. Based on polyamide, these net bleeders are heat-setted for the purpose of avoiding the rolling up of the flanges.



Vacuum Infusion Ancillaries


CFI’s range of products from Diatex is home to a number of fittings, valves, adapters and consumable hoses for vacuum infusion. This range of fittings and valves is available in several diameters to cover all needs, and ranges across products such as plugs, vacuum channel and infusion line, plugs and connectors, as well as assembly adhesive spray.

Products within this range include Infusion Plugs Eco, Spiral Plugs Eco, SPIRALPLEX, Plugs and Connectors, Spiral Tubing, MEGATAC, DIADRAIN PA80, Infusion Plugs, Spiral Plugs, DIADRAIN, DIABREAKER and Spiral MP.


Multilayer Systems for Vacuum Moulding


Diatex has designed a specific range of bagging materials for pre-pregs and hand lay-up composite materials with vacuum polymerization. The success of Diatex is based on the manufacturing of innovative products, such as Vacuopeel, Vacuoplex and Vacuolease. The purpose of these products are to facilitate the application of environmental products by users during drape moulding operations.


Bagging Films


CFI is home to Diatex’s wide range of bagging films for vacuum moulding and vacuum infusion.

PA205 HF is a carved bagging film for the vacuum moulding of composite parts. Its 3D structure provides a suitable vacuum compacting and allows to take out the bleeder for compaction or vacuum moulding combined to the Microporous peel ply. PA205 HF is an environmentally friendly bagging film as it enables using less peripheral device.


Copolymer Films

Bagging films advantages expected by professionals in the composite industries:

  • Flexibility
  • Mechanical and temperature resistance
  • Airtight


Polyamide Films

Used in high temperature applications, polyamide films offer great mechanical strength and are compatible with autoclave processes.


Technical Films

Diatex offers a range of very high elongation films to save time during vacuum moulding processes, as well as very high temperature-resistant films.


Release Films


Diatex offers a range of perforated and non perforated release films for high temperature applications that are available through Composite Fibreglass International. Polyolefin films release with the majority of resins. Fluoropolymer films release with all types of resins.


Peel Piles


Diatex developed a complete range of peel plies: from 50 to 185 gr/m², dyed or undyed, with stripes, polyamide or polyester, bands or full width.

PA85 is the standard quality, taffetas weave, white with stripes. These fabrics are used to impart a textured surface to the moulded component to improve adhesion in secondary painting or bonding. Diatex have the ability to manufacture custom peel ply with specific characteristics for all clients.

All of Diatex’s peel plies are treated in order to avoid bringing any pollutant (such as silicones) into the finished product. They use processes that allow for the control of the products’ porosity to guarantee the repetitiveness of the infusion process.

To respond to the requirements of the EN9100 standard, Diatex secure client’s productions with their unique automatic FOD (foreign object debris) tracking system. Diatex inspects all of its technical peel plies made for composite structural bonding with this new machine. Using AI (artificial intelligence), they have the ability to scan fabric, detect and classify FODs. A full report of this scan (cartography) including pictures of accepted and non-accepted FODs is also available to clients once this process is complete.



Release Agents


Diatex holds a long-standing partnership with Chem-Trend

Minimising the environmental impact of Chem-Trend’s products has been a priority from the beginning. Notably the use of VOCs in solvent-based mould release agents. Today, Chem-Trend is the industry pioneer in the development of innovative solutions.

With the Zyvax® product range, manufacturers of moulds for composite materials for the aerospace industry benefit from advanced technology, incredibly simple application, outstanding quality, process efficiency and value for money.

Many Zyvax® products are water-based, thus complying with environmental and legal requirements. Zyvax® has been exclusively distributed by Diatex since 1994 and is the most powerful range of water-based release agents on the market.
