is suitable for the production of GRP parts with open and closed mould technologies such as injection moulding, RTM, pressing, vacuum forming and continuous lamination moulding. With this type of production technologies, it gives several characteristics to the moulded part due to its very good deformability, homogeneous impact strength of the core and thin laminate capability. This product meets the main demands of customers in terms of part stiffness, labour savings and good surface

Lavesan is constantly investing in new technology and updated equipment so as to increase production output and sales. Profits are re-invested to improve equipment or enlarge and renovate buildings and warehouses, so as to improve worker health and safety and to maintain the company’s organization and production at its best.

aspect. This does not exclude that several advantages could also be valid for Lavecore built up with several fabrics.

the counter-mould (facilitating the development of the film or latex), excellent slipping of gelcoat against the mould and easy inclusion of any inserts or reinforcements. It also facilitates filling in the corners, thus reducing the risk of bubbles or cracking in these areas, and limits part twist. Lavecore eliminates layer overlapping problems, thus limiting the risk of layer displacement within the mould. When injected, it favours a good seal at the junction of the plan. The tissue allows sharps cuts without imperfections, resulting in raw-material savings (waste is reduced to a minimum), production time savings and minimized impurities in the working. n

Main advantages
This material can be moulded directly, without heating. Its structure allows for cold forming without any alteration of its chemical and physical properties. It offers good stretching properties in both directions, good adaptability to the undulations of the mould, good integrity and no need for adhesive retention. The time required to position it in the mould is also reduced. The material’s softness is an interesting property, combined with low odour, optimized descent times for
