COMPOSCIENCE GMBH

CTRA studies and proposes technical solutions for the transfer of all fluids over long distances, combining chemical compatibility with mechanical and abrasive resistance to ensure a long service life without routine maintenance. The reference project carried out by CTRA in 2006 on behalf of OCP Morocco, which involved the construction of two Ø1800 phosphogypsum discharge lines with a total length of 8km, is a perfect illustration of this. These pipes combine chemical, abrasive and mechanical resistance, and were buried at a depth of more than 12m to ensure a gravity flow rate for a charged fluid. This project required the processing of 3400 tonnes of GRP vinylester over 24 months and was the subject of a case history.

Windstrand® 2000 features a powerful combination of optimized design and reliability for longer, lighter blades. Windstrand® 2000 delivers high weaving efficiencies. The product allows blades to operate in extreme environments at reduced operating costs. We’re happy to offer Windstrand® 2000 in all regions. Packaging (Standard Reference) Rovings are available in a singleend internalpull package. Each pallet weighs approximately 1 ton. Pallets are stretch wrapped for load stability. All doffs are wrapped with TackPak™ for protection and to aid package runout and transfer. Full doffs are approximately 2021 kg (45 lb.) and they can be packaged in bulk or CreelPak™ format. Standard Package Cylindrical bobbin without tube, Outside Diameter (OD) ±270mm, height 260300mm. Partial bobbins have smaller diameter. Max bobbin weight approximately 21kg. 600 Tex and greater. Bobbin covered by a TackPack™ film. Pallet Size 1150x1150mm, 4 ways entry.

PulStrand® 4100 is specifically designed for fast wetout, good processing, high glass loading and excellent laminate properties, to maximize customers’ processing and minimize their processing costs in pultrusion applications. OUTSTANDING MECHANICAL PROPERTIES Excellent shear and flexural properties in major resin systems, provide maximum part strength and long part service life. REDUCED COST Fast, uniform strand wetout leads to higher glass loading, reducing resin demand; fast wetout also increases production speed and productivity resulting in reduced manufacturing cost. MULTIRESIN COMPATIBILITY Excellent glass/resin bonding in polyester, vinyl ester, polyurethane, acrylic, and epoxy resins, providing the processor maximum flexibility with one input glass. This reduces cost with less inventory to carry and eliminates the need for costly downtime and labor to change input glass during job changes. Suitable for LFTP PA compounding applications

PipeStrand® S2300 is made for fabricators that want to reduce material cost, while increasing the performance of their filament wound products. Designed to increase production efficiency, while providing excellent hydrothermal stability under pressurized conditions. OUTSTANDING MECHANICAL PROPERTIES Excellent properties in both amine and anhydride curing systems; improved axial tensile strength, interlaminate shear strength and burst stress for high performance filament wound epoxy applications. REDUCE COST Designed for use in filament winding, in both epoxy amine and anhydride curing systems — giving flexibility with one glass input and higher glass loading. GREAT STRAND WETOUT Excellent processing range, fast wetting and smooth pipe surface. LONG SERVICE LIFE Excellent hydrothermo stability and strength retention under pressurized conditions, leading to long service life for installed pipe.
