Under the designation WACOSIT® we supply fibre-reinforced pultrusion and filament profiles with many advantages given by these:

• WACOSIT® has good mechanical, thermal and electrical properties and is resistant to corrosion, moisture, as well as to many chemicals.

• WACOSIT® is characterised by a very smooth surface and repro-ducible dimensional accuracy. Generally there is no further mechanical processing or finishing necessary.

• WACOSIT® makes tailored solutions possible from the diversity of the types which are available. For a particular application, this might be a version e.g. for high resistance to weathering, with an electrically conductive surface, as the flame-retardant version, or in a non-standard colour.

• WACOSIT® can be produced in any arbitrary length – the length is only limited by the requirements for trans-portation. This constitutes a considerable advantage over profiles made from sheet material reinforced with glass fibres.

• WACOSIT® can be processed further without any difficulty. This is because the profiles are washed, trovalised and, if requested, processed for ready-to-use by the customer. The product is thus completely dust-free. Parts to be adhesive-bonded can be supplied with an additional “peel-off fabric” – this cuts out the work of having to grind down or roughen the surfaces to be bonded.

Tools are available for selection from more than 5000 pultruded WACOSIT® profiles, the exact dimensions for which can be taken from the applicable WACOSIT® profile list. We will of course customise a profile to your specifications. Winding mandrels are available for more than 500 WACOSIT® wound components. These mandrels are high-precision items from our own machining shop. Thus we are best equipped to fulfil your requirements.

WACOSIT®-Profile profiles are realised by the “Pultrusion method”. Reinforcing fibres are impregnated with synthetic resins and cured continuously in a heated mould. Besides glass fibres, WACOSIT® profiles can be strengthened by carbon fibres or by aramide fibres. Variants of these are also available to best meet the differing requirements.

Thus for example, there are also the R, S and T types of glass fibres available. These are characterised by better mechanical properties over the more commonly used E type of glass fibre. Alongside rovings, there are also other fabric structures such as tapes and warp-knit complexes which are also used in engineering WACOSIT® profiles. As matrix systems we process polyester,vinyl ester and epoxy resins.

In the fibre composite, the mechanical strength and the modulus of elasticity are determined by the reinforcing fibre used whereas the thermal behaviour, abrasion resistance and resistance to chemical attack are all dependent in the first instance on the matrix. Additional fabric tape and glass matting can be used to give WACOSIT® profiles a better compressive strength and sheering resistance properties. WACOSIT® profiles can also be taped with rovings in a criss-cross pattern to improve the mechanical properties even further.

WACOSIT® profiles can be sawn, machined, turned, drilled, groundand, up to a certain thickness, be punched as well. Subsequent processing of dimensionally accurate produced parts is not normally necessary. Processing requires the use of hard-metal or diamond- tipped tools.

WACOSIT® profiles, wound components and guying elements have asserted themselves in many areas of applications as dependable constructional parts.

WACOSIT® has its permanent place in electrical engineering, mechanical and plant construction, sports and leisure, automotive and transport applications, structural and civil engineering as well as in the cable industry.
