The company 3B the fibreglass company expands his range of thermoplastic products of long fibre/fiber (LFT)

The company 3B the fibreglass company show his paper of leader in the field of the supply of solutions of reinforcements of fibre/fiber of glass with the presentation of the 4535, a roving direct for compounds of thermoplastic polyamide of long fibre/fiber (PA LFT). This roving complements to the 4220, allocated to compound PP LFT (polipropileno), and confirms the commitment of 3B to have a majority paper in the field of the reinforcements of LFT. This market has experienced a very strong growth in the last years, until the 85 percent only in the sector of automotion. Although the resin of polipropileno dominates the range of materials used at present, the alternative polymers like the polyamide have clear opportunities in the most demanding applications.

Eric Martin, director of Development of Businesses for Termoplasticos of 3B, says: "The replacement of metals has gone in in a new phase, that forces still more the limits of provision of the thermoplastic materials. Although the key incentives keep on being the reduction of the cost of the systems, the increase of the flexibility of design and the saving of weight, also is working in the requirements of provision to make possible a functional integration more complex, an absorption of energy higher for a wide range of temperatures and an alabeo very small". Nowadays, the thermoplastic reinforced with fibre/fiber of long glass are the ideal materials for designs of light weight, especially for components semiestructurales big or components of high load of applications of automotion, appliances or machines tools.

The fibre/fiber of glass constitutes a structural element critic of the compounds reinforced with LFT place that creates a three-dimensional skeleton complicated in the interior of the piece moldeada final. This skeleton provides characteristic and physical properties, like dimensional stability and resistance to the distortion, inhibition of the propagation of cracks and better resistance to the impact to temperatures so much high like drops. Paul Cazes, director of Thermoplastic Products of 3B, adds: "The roving of 3B 4535 nourishes of the long innovative experience of this company in the field of the reinforcements for polyamide. The chemical scoop of ensimaje (sizing) is specifically designed to provide excellent wet-out and an optimum adhesion and transfer of the load between the fibre/fiber and the resin to offer exceptional mechanical properties".

"His excellent impregnación and his high speed of processed does that this product was adapted for all the processes of LFT (G-LFT, D-LFT, etc.). The wallet of reinforcements LFT of 3B will follow expanding in the future with seen to satisfy the new requirements of this emergent market", it concludes Cazes. The roving 4535 of 3B is available in 17 µm with 1200 tex (4535 17 1200) and 2400 tex (4535 17 2400) and is of fibre/fiber of glass Advantex, that combines the electrical properties and mechanics of the glass And traditional with the resistance to the corrosion and the durability of the glass And-CR (ASTM D578). 3B has launched today the new roving 4535 in the fair Composites Europe, where is present in the Pavilion 4 (Stand 17).
